*1. The applicable load current depends on the ambient temperature. For details, refer to Load Current vs. Ambient Temperature in Engineering
Data on page 1235.
*2. Applicable Load
Use the following formula to calculate the maximum total capacity of a heater load for a three-phase balanced load with delta connections.
Maximum load capacity = Load current × Load voltage × √3
Example: 15 A × 200 V × √3 = 5,196 W ≅ 5.1 kW
Example: 15 A × 400 V × √3 = 10,392 W ≅ 10.3 kW

Note: The heat sink area is the combined
area of all surfaces of the heat sink
that radiate heat.
For the G3PE-525B-3H, when a
current of 18 A flows through the SSR
at 40°C, the graph shows that a heat
sink area of about 2,500 cm2 would
be required. Therefore, if the heat
sink is square, one side of an
aluminum plate in the heat sink must
be 36 cm or longer (√2,500 (cm2)/2 =
36 cm (rounded to a whole number)).

Safety Precautions for All G3PE Models
For common precautions, refer to Safety Precautions for All Solid-state Relays on page 1191.
CAUTION
Minor electrical shock may occasionally occur.
Do not touch the G3PE terminal section (i.e., currentcarrying parts) while the power is being supplied.
Also, always attach the cover terminal.
The G3PE may rupture if short-circuit current flows.
As protection against accidents due to shortcircuiting, be sure to install protective devices, such
as fuses and no-fuse breakers, on the power supply
side.
Minor electrical shock may occasionally occur.
Do not touch the main circuit terminals on the G3PE
immediately after the power supply has been turned
OFF. Shock may result due to the electrical charge
stored in the built-in snubber circuit.
Minor burns may occasionally occur.
Do not touch the G3PE or the heat sink while the
power is being supplied or immediately after the
power supply has been turned OFF. The G3PE and
heat sink become extremely hot.
Precautions for Safe Use
OMRON constantly strives to improve quality and reliability.
SSRs, however, use semiconductors, and semiconductors may
commonly malfunction or fail. In particular, it may not be possible to
ensure safety if the SSRs are used outside the rated ranges.
Therefore, always use the SSRs within the ratings. When using an
SSR, always design the system to ensure safety and prevent human
accidents, fires, and social harm in the event of SSR failure. System
design must include measures such as system redundancy,
measures to prevent fires from spreading, and designs to prevent
malfunction.
Transport
Do not transport the G3PE under the following conditions.
Doing so may result in damage, malfunction, or deterioration of
performance characteristics.
• Conditions in which the G3PE may be subject to water.
• Conditions in which the G3PE may be subject to high temperature
or high humidity.
• Conditions in which the G3PE is not packaged.
Operating and Storage Environments
Do not use or store the G3PE in the following locations. Doing so may
result in damage, malfunction, or deterioration of performance
characteristics.
• Locations subject to rainwater or water splashes.
• Locations subject to exposure to water, oil, or chemicals.
• Locations subject to high temperature or high humidity.
• Do not store in locations subject to ambient storage temperatures
outside the range −30 to 100°C.
• Do not use in locations subject to relative humidity outside the
range 45% to 85%.
• Locations subject to corrosive gases.
• Locations subject to dust (especially iron dust) or salts.
• Locations subject to direct sunlight.
• Locations subject to shock or vibration.
Installation and Handling
• Do not block the movement of the air surrounding the G3PE or heat
sink. Abnormal heating of the G3PE may result in shorting failures
of the output elements or burn damage.
• Do not use the G3PE if the heat radiation fins have been bent by
being dropped. Doing so may result in malfunction due to a
reduction in the heat radiation performance.
• Do not handle the G3PE with oily or dusty (especially iron dust)
hands. Doing so may result in malfunction.
• Attach a heat sink or radiator when using an SSR. Not doing so
may result in malfunction due to a reduction in the heat radiation
performance.
Installation and Mounting
• Mount the G3PE in the specified direction. Otherwise excessive
heat generated by the G3PE may cause short-circuit failures of the
output elements or burn damage.
• Make sure that there is no excess ambient temperature rise due to
the heat generation of the G3PE. If the G3PE is mounted inside a
panel, install a fan so that the interior of the panel is fully ventilated.
• Make sure the DIN track is securely mounted. Otherwise, the
G3PE may fall.
• When mounting the heat sink, do not allow any foreign matter
between the heat sink and the mounting surface. Foreign matter
may cause malfunction due to a reduction in the heat radiation
performance.
• If the G3PE is mounted directly in a control panel, use aluminum,
steel plating, or similar material with a low heat resistance as a
substitute for a heat sink. Using the G3PE mounted in wood or
other material with a high heat resistance may result in fire or
burning due to heat generated by the G3PE.
Installation and Wiring
• Use wires that are suited to the load current. Otherwise, excessive
heat generated by the wires may cause burning.
• Do not use wires with a damaged outer covering.
Otherwise, it may result in electric shock or ground leakage.
• Do not wire any wiring in the same duct or conduit as power or
high-tension lines. Otherwise, inductive noise may damage the
G3PE or cause it to malfunction.
• When tightening terminal screws, prevent any non-conducting
material from becoming caught between the screws and the
tightening surface. Otherwise, excessive heat generated by the
terminal may cause burning.
• Do not use the G3PE with loose terminal screws. Otherwise,
excessive heat generated by the wire may cause burning.
• For the G3PE models with a carry current of 35 A or larger, use M5
crimp terminals that are an appropriate size for the diameter of the
wire.
• Always turn OFF the power supply before performing wiring. Not
doing so may cause electrical shock.
Installation and Usage
• Select a load within the rated values. Not doing so may result in
malfunction, failure, or burning.
• Select a power supply within the rated frequencies. Not doing so
may result in malfunction, failure, or burning.
• If a surge voltage is applied to the load of the Contactor, a surge
bypass(*) will function to trigger the output element. The G3PE
therefore cannot be used for motor loads. Doing so may result in
load motor malfunction.
* Surge Bypass
This circuit protects the output circuit from being destroyed. This
suppresses the surge energy applied inside the SSR in comparison
with a varistor for the main circuit protection. By alleviating electrical
stress on the electronic components of the SSR's output circuit,
failure and destruction due to surge voltage are suppressed.
Reference value: Surge dielectric strength of 30 kV min.
(Test conditions: 1.2 ✕ 50 μs standard voltage waveform, peak voltage
of 30 kV, repeated 50 times according to JIS C5442)

G3PE
Precautions for Correct Use
The SSR in operation may cause an unexpected accident.
Therefore it is necessary to test the SSR under the variety of
conditions that are possible. As for the characteristics of the SSR, it is
necessary to consider differences in characteristics between
individual SSRs.
The ratings in this catalog are tested values in a temperature range
between 15°C and 30°C, a relative humidity range between 25% and
85%, and an atmospheric pressure range between 86 and 106 kPa.
It will be necessary to provide the above conditions as well as the load
conditions if the user wants to confirm the ratings of specific SSRs.
Causes of Failure
• Do not drop the G3PE or subject it to abnormal vibration or shock
during transportation or mounting. Doing so may result in
deterioration of performance, malfunction, or failure.
• Tighten each terminal to the torque specified below. Improper
tightening may result in abnormal heat generation at the terminal,
which may cause burning.

• Do not use or store the G3PE in the following conditions. Doing so
may result in deterioration of performance.
• Locations subject to static electricity or noise
• Locations subject to strong electric or magnetic fields
• Locations subject to radioactivity

• Make sure that all lead wires are thick enough for the current.
• For three-element and two-element models, the output terminal will
be charged even when the Relay is OFF. Touching the terminal
may result in electric shock. To isolate the Relay from the power
supply, install an appropriate circuit breaker between the power
supply and the Relay.
Always turn OFF the power supply before wiring the Unit.
• Terminal L2 and terminal T2 of a 2-element model are internally
connected to each other. Connect terminal L2 to the ground
terminal of the power supply.
If terminal L2 is connected to a terminal other than the ground
terminal, cover all the charged terminals, such as heater terminals,
to prevent electric shock and ground faults.

EMC Ditective Compliance
Mounting to Control Panel
EMC direcives can be complied with under the following conditions.
The G3PE is heavy. Firmly mount the DIN track and secure both ends
with End Plates for DIN-track-mounting models. When mounting the
G3PE directly to a panel, firmly secure it to the panel.
If the panel is airtight, heat from the SSR will build up inside, which
may reduce the current carry ability of the SSR or adversely affect
other electrical devices. Be sure to install ventilation holes on the top
and bottom of the panel.

This is a Class A product (for industrial environments). In a domestic
environment, the G3PE may cause radio interference, in which case
the user may be required to take appropriate measures.
Noise and Surge Effects
If noise or an electrical surge occurs that exceeds the malfunction
withstand limit for the G3PE output circuit, the output will turn ON for
a maximum of one half cycle to absorb the noise or surge. Confirm
that turning the output ON for a half cycle will not cause a problem for
the device or system in which the G3PE is being used prior to actual
use. The G3PE malfunction withstand limit is shown below.
• Malfunction withstand limit (reference value): 500 V
Note: This value was measured under the following conditions.
Noise duration: 100 ns and 1 μs
Repetition period: 100 Hz
Noise application time: 3 min
Mounting Models with Externally Attached Heat Sinks
• Before attaching an external Heat Sink or Radiator to the Unit,
always apply silicone grease, such as Momentive Performance
Material’s YG6260 or Shin-Etsu Chemical’s G747, to the mounting
surface to enable proper heat radiation.
• Tighten the screws to the following torque to secure the Unit and
external Heat Sink or Radiator to enable proper heat dissipation.

Note: 1. If the air inlet or air outlet has a filter, clean the filter regularly
to prevent it from clogging to ensure an efficient flow of air.
2. Do not locate any objects around the air inlet or air outlet,
otherwise the objects may obstruct the proper ventilation of
the control panel.
3. A heat exchanger, if used, should be located in front of the
G3PE to ensure the efficiency of the heat exchanger.
G3PE Ambient Temperature
The rated current of the G3PE is measured at an ambient
temperature of 40°C.
The G3PE uses a semiconductor to switch the load. This causes the
temperature inside the control panel to increase due to heating
resulting from the flow of electrical current through the load. The
G3PE reliability can be increased by adding a ventilation fan to the
control panel to dispel this heat, thus lowering the ambient
temperature of the G3PE.
(Arrhenius's law suggests that life expectancy is doubled by each
10°C reduction in ambient temperature.)

Solid State Relays Common Precautions
●For precautions on individual products, refer to "■Precautions" in individual product information.
CAUTION
Touching the charged section is likely to cause
electric shock. Do not touch the SSR terminal
section (the charged section) when the power
supply is ON. For SSRs with terminal covers, be
sure to attach the cover before use.
The SSR and heat sink will be hot and are likely to
cause burns. Do not touch the SSR or the heat sink
either while the power supply is ON, or
immediately after the power is turned OFF.
The internal snubber circuit is charged and will
cause electric shock. Do not touch the SSR load
terminal immediately after the power is turned OFF.
Electric shock is likely to result. Be sure to
conduct wiring with the power supply turned OFF.
SSRs may occasionally explode. Do not apply a
short-circuit current to the load side of an SSR.
To protect against short-circuit accidents, be sure
to install a protective device, such as a
quick-break fuse etc. on the power supply line.
Safety Cautions
OMRON constantly strives to improve quality and reliability. SSRs,
however, use semiconductors, and semiconductors may commonly
malfunction or fail. Short-circuit failures represent the main failure
mode and can result in an inability to shut OFF the load. Therefore,
for fail-safe operation of control circuits that use SSRs, do not use
circuits that shut OFF the load power supply only with an SSR, but
rather also use circuits with a contactor or breaker that shuts off the
load when the SSR fails. In particular, it may not be possible to
ensure safety if the SSRs are used outside the rated ranges.
Therefore, always use the SSRs within the ratings.
When using an SSR, always design the system to ensure safety
and prevent human accidents, fires, and social harm in the event
of SSR failure. System design must include measures such as
system redundancy, measures to prevent fires from spreading,
and designs to prevent malfunction.
1. Do not apply voltage or current in excess of the ratings to the
terminals of the SSR. Doing so may result in failure or burn
damage.
2. Heat Radiation
x Be careful with the increase in ambient temperature caused
by self-heating. Mount a fan etc. to provide a sufficient air
ventilation especially in case of internal mounting.
x Mount the SSR following the specified mounting orientation.
The abnormal heat generation from the body may cause
output elements to short or may cause burning.
3. Perform correct wiring following the precautions below.
Improper wiring may lead to abnormal heating resulting in burn
damage to the SSR once the power is supplied.
x Use a suitable wire according to the load current. Otherwise
the abnormal heating of the wire may cause burning.
4. Operating Conditions
x Designate the load within the rated range. Otherwise it may
result in faulty operation, malfunction, or burning.
x Use a power supply within the rated frequency range.
Otherwise it may result in faulty operation, malfunction, or
burning.
5. Do not transport the SSR under the following conditions.
Failure, malfunction, or deterioration of performance
characteristics may occur.
x Conditions under which the SSR will be exposed to water
x High temperatures or high humidity
x Without proper packing
6. Operating and Storage Environment
Do not use or store the SSR in the following environments.
Doing so may result in damage, malfunction, or deterioration
of performance characteristics.
x Do not use or store in environments subject to exposure
to sunlight.
x Do not use in environments subject to temperatures
outside the range specified individually.
x Do not use in environments subject to relative humidity
outside the range of 45% to 85% RH, or in locations
subject to condensation as the result of severe changes
in temperature.
x Do not store in environments subject to temperatures
outside the range specified individually.
x Do not use or store in environments subject to corrosive
or flammable gases.
x Do not use or store in environments subject to dust, salt,
or iron dust, or in locations subject to salt damage.
x Do not use or store in environments subject to shock or
vibration.
x Do not use or store in environments subject to exposure
to water, oil, or chemicals, or in environments subject to
exposure to rain and water splashes.
x Do not use or store in environments subject to high
temperature or high humidity.

Solid State Relays Common Precautions
Precautions for Correct use
●Before Using SSR
1. The SSR in operation may cause an unexpected accident.
Therefore it is necessary to test the SSR under the variety of
conditions that are possible.
For example, as for the characteristics of the SSR, it is
necessary to consider differences in characteristics between
individual SSRs.
2. The ratings in this catalog are tested values in a temperature
range between 15°C and 30°C, a relative humidity range
between 25% and 85%, and an atmospheric pressure range
between 88 and 106 kPa. It will be necessary to provide the
above conditions as well as the load conditions if the user
wants to confirm the ratings of specific SSRs.
2. Inductive Noise
Do not wire power lines alongside the input lines. Inductive
noise may cause the SSR to malfunction. If inductive noise is
imposed on the input terminals of the SSR, use the following
cables according to the type of inductive noise, and reduce the
noise level to less than the must release voltage of the SSR.
Twisted-pair wire: For electromagnetic noise
Shielded cable: For static noise
A filter consisting of a combination of capacitor and resistor will
effectively reduce noise generated from high-frequency
equipment.
■Input Circuit
There is variation in the input impedance of SSRs. Therefore, do
not connect multiple inputs in series. Otherwise malfunction may
occur.
Load
●Connecting to the Input Side
Filter

device
●Input Noise
SSRs need only a small amount of power to operate. This is why
the input terminals must shut out electrical noise as much as
possible. Noise applied to the input terminals may result in
malfunction. The following describes measures to be taken
against pulse noise and inductive noise.
1. Pulse Noise
A combination of capacitor and resistor can absorb pulse
noise effectively. The following is an example of a noise
absorption circuit with capacitor C and resistor R connected to
an SSR incorporating a photocoupler.
Pulse width
R
C
Note: R: 20 to 100 Ω
C: 0.01 to 1 μF
●Input Conditions
1. Input Voltage Ripples
When there is a ripple in the input voltage, set the input
voltage so that the peak voltage is lower than the maximum
operating voltage and the root voltage is above the minimum
operating voltage.
Peak voltage
Root voltage
0V
2. Countermeasures for Leakage Current
When the SSR is powered by transistor output, the must
release voltage may be insufficient due to leakage current
while power is OFF. To counteract this, connect bleeder
resistance as shown in the diagram below and set the bleeder
resistance so that VR is half of the release voltage or less.
Pulse voltage
Pulse width (μs)
The value of R and C must be decided carefully. The value of
R must not be too large or the supply voltage (E) will not be
able to satisfy the required input voltage value. The larger the
value of C is, the longer the release time will be, due to the
time required for C to discharge electricity.

Note. For low-voltage models, sufficient voltage may not be applied to the
SSR because of the relationship between C, R, and the internal
impedance. When deciding on a value for R, check the input
impedance for the SSR.

below.

Solid State Relays Common Precautions
3. ON/OFF Frequency
An SSR has delay times called the operating time and release
time. Loads, such as inductive loads, also have delay times
called the operating time and release time. These delays must
all be considered when determining the switching frequency.
4. Input impedance
In SSRs which have wide input voltages (such as G3CN and
G3TB), the input impedance varies according to the input
voltage and changes in the input current.
For semiconductor-driven SSRs, changes in voltage can
cause malfunction of the semiconductor, so be sure to check
by the actual device before usage.
See the following examples.

●DC Switching SSR Output Noise Surges
When an L load, such as a solenoid or electromagnetic valve, is
connected, a diode that prevents counter-electromotive force. If
the counter-electromotive force exceeds the withstand voltage of
the SSR output element, it could result in damage to the SSR
output element. To prevent this, insert the element parallel to the
load, as shown in the following diagram and table.
Load
SSR
INPUT
As an absorption element, the diode is the most effective at
suppressing the counter-electromotive force. The release time
for the solenoid or electromagnetic valve will, however, increase.
Be sure to check the circuit before use. To shorten the time,
connect a Zener diode and a regular diode in series. The release
time will be shortened at the same rate that the Zener voltage
(Vz) of the Zener diode is increased.

●AC Switching SSR Output Noise and Surges
x In case there is a large voltage surge in the AC current being
used by the SSR, the RC snubber circuit built into the SSR
between the SSR load terminals will not be sufficient to
suppress the surge, and the SSR transient peak element
voltage will be exceeded, causing overvoltage damage to the
SSR.
x Only the following models have a built-in surge absorbing
varistor: G3NA, G3S, G3PA, G3NE, G3PH, G3DZ (some
models), G3RZ, and G3FM. When switching an inductive load
with any other models, be sure to take countermeasures
against surge, such as adding a surge absorbing element.
x In the following example, a surge voltage absorbing element
has been added.

Self-holding circuits must use mechanical relays. (SSRs cannot
be used to design self-holding circuits.)

4. Transformer Load
When the SSR is switched ON, an energizing current of 10 to
20 times the rated current flows through the SSR for 10 to 500
ms. If there is no load in load side circuit, the energizing
current will reach the maximum value. Select an SSR so that
the energizing current does not exceed half the inrush current
resistance of the SSR.
5. Half-wave Rectifying Circuit
AC electromagnetic counters or solenoids have built-in diodes,
which act as half-wave rectifiers. For these types of loads, a
halfwave AC voltage does not reach the SSR output. For
SSRs with the zero cross function, this can cause them not to
turn ON. Two methods for counteracting this problem are
described below.
1. Connect a bleeder resistance with approximately 20% of the
SSR load current.
Bleeder resistance
Load
1. Heater Load (Resistive Load)
A resistive load has no inrush current. The SSR is generally
used together with a pulse-voltage-output in temperature
controller for heater ON/OFF switching. When using an SSR
with the zero cross function, most generated noise is
suppressed. This type of load does not, however, include
all-metal and ceramic heaters. Since the resistance values at
normal temperatures of all-metal and ceramic heaters are low,
an overcurrent will occur in the SSR, causing damage. For
switching of all-metal and ceramic heaters, select a Power
Controller (G3PW, consult your OMRON representative) with a
long soft-start time, or a constant-current switch.
2. Use SSRs without the zero cross function.
6. Full-wave Rectified Loads
AC electromagnetic counters and solenoids have built-in
diodes, which act as full-wave rectifiers. The load current for
these types of loads has a rectangular wave pattern, as shown
in the following diagram.
Heater load
Temperature

200
Accordingly, AC SSRs use a triac (which turns OFF the
element only when the circuit current is 0 A) in the output
element. If the load current waveform is rectangular, it will
result in an SSR release error.
When switching ON and OFF a load whose waves are all
rectified, use Power MOS FET Relay.
-V-model SSRs: G3F-203SL-V, G3H-203SL-V

3. Motor Load
When a motor is started, an inrush current of 5 to 10 times the
rated current flows and the inrush current flows for a longer
time than for a lamp or transformer. In addition to measuring
the startup time of the motor or the inrush current during use,
ensure that the peak value of the inrush current is less than
half the inrush current resistance when selecting an SSR. The
SSR may be damaged by counterelectromotive force from the
motor. Be sure to install overcurrent protection for when the
SSR is turned OFF.
7. Small-capacity Loads
Even when there is no input signal to the SSR, there is a small
leakage current (IL) from the SSR output (LOAD). If this
leakage current is larger than the load release current, the
SSR may fail to release. Connect a bleeder resistance R in
parallel to increase the SSR switching current.

2. Lamp Load
A large inrush current flows through incandescent lamps,
halogen lamps, and similar devices (approx. 10 to 15 times
higher than the rated current). Select an SSR so that the peak
value of inrush current does not exceed half the inrush current
resistance of the SSR. Refer to “Repetitive” (indicated by the
dashed line) shown in the following figure. When a repetitive
inrush current of greater than half the inrush current resistance
is applied, the output element of the SSR may be damaged.

Solid State Relays Common Precautions
8. Inverter Load
Do not use an inverter-controlled power supply as the load
power supply for the SSR. Inverter-controlled waveforms
become rectangular, so the dV/dt ratio is extremely large and
the SSR may fail to release.
An inverter-controlled power supply may be used on the input
side provided the effective voltage is within the normal
operating voltage range of the SSR.
Trigger voltage
0
Trigger voltage

A and B: Loss time
ΔV/ΔT = dV/dt: voltage increase ratio
The dV/dt ratio tends to infinity,
so the SSR will not turn OFF.
Voltage waveform
9. Capacitive Load
The supply voltage plus the charge voltage of the capacitor is
applied to both ends of the SSR when it is OFF. Therefore, use
an SSR model with an input voltage rating twice the size of the
supply voltage. Limit the charge current of the capacitor to less
than half the peak inrush current value allowed for the SSR.
10. SSR for DC Switching
Connection
With the SSR for DC switching, the load can be connected to
either negative (-) or positive (+) output terminal of the SSR.
Protective Component
Since the SSR does not incorporate an overvoltage absorption
component, be sure to connect an overvoltage absorption
component when using the SSR under an inductive load.
■Load Power Supply
1. Rectified Currents
If a DC load power supply is used for full-wave or half-wave
rectified AC currents, make sure that the peak load current does
not exceed the maximum usage load power supply of the SSR.
Otherwise, overvoltage will cause damage to the output element
of the SSR.
Peak voltage
SSR operating
voltage maximum
value
Current waveform
An inductance (L) load
causes a current phase delay
as shown on the left.
Therefore, the loss is not as
great as that caused by a
resistive (R) load.
This is because a high
voltage is already imposed on
the SSR when the input
current to the SSR drops to
zero and the SSR is turned
OFF.
4. Phase-controlled AC Power Supplies
Phase-controlled power supply cannot be used.
■Operating and Storage Environments
1. Operating Ambient Temperature
The rated value for the ambient operating temperature of the
SSR is for when there is no heat build-up. For this reason, under
conditions where heat dissipation is not good due to poor
ventilation, and where heat may build up easily, the actual
temperature of the SSR may exceed the rated value resulting in
malfunction or burning.
When using the SSR, design the system to allow heat dissipation
sufficient to stay below the “●Load Current vs. Ambient
Temperature” characteristic curve. Note also that the ambient
temperature of the SSR may increase as a result of
environmental conditions (e.g., climate or air-conditioning) and
operating conditions (e.g., mounting in an airtight panel).
2. Transportation
2. Operating Frequency for AC Load Power Supply
The operating frequency range for an AC load power supply is 47
to 63 Hz.
When transporting the SSR, observe the following points. Not
doing so may result in damage, multifunction, or deterioration of
performance characteristics.
3. Low AC Voltage Loads
3. Vibration and Shock
If the load power supply is used under a voltage below the
minimum operating load voltage of the SSR, the loss time of the
voltage applied to the load will become longer than that of the
SSR operating voltage range. See the following load example.
(The loss time is A < B.)
Before operating the SSR, make sure that this loss time will not
cause problems.
If the load voltage falls below the trigger voltage, the SSR will not
turn ON, so be sure to set the load voltage to 75 VAC min.
Do not subject the SSR to excessive vibration or shock.
Otherwise the SSR may malfunction and internal components
may be damaged.
To prevent the SSR from abnormal vibration, do not install the
SSR in locations or by means that will subject it to vibration from
other devices, such as motors.
4. Solvents
Do not allow the SSR to come in contact with solvents, such as
thinners or gasoline. Doing so will dissolve the markings on the
SSR.
5. Oil
Do not allow the SSR terminal cover to come in contact with oil.
Doing so will cause the cover to crack and become cloudy.
26
Solid State Relays Common Precautions
■Actual Operation
■Safety Concept
1. Leakage Current
1. Error Mode
A leakage current flows through a snubber circuit in the SSR
even when there is no input. Therefore, always turn OFF the
input or load and check that it is safe before replacing or wiring
the SSR.
The SSR is an optimum relay for high-frequency switching and
highspeed switching, but misuse or mishandling of the SSR may
damage the elements and cause other problems. The SSR
consists of semiconductor elements, and will break down if these
elements are damaged by surge voltage or overcurrent. Most
faults associated with the elements are short-circuit
malfunctions, whereby the load cannot be turned OFF.
Therefore, to provide a safety feature for a control circuit using an
SSR, design a circuit in which a contactor or circuit breaker on
the load power supply side will turn OFF the load when the SSR
causes an error. Do not design a circuit that turns OFF the load
power supply only with the SSR. For example, if the SSR causes
a half-wave error in a circuit in which an AC motor is connected
as a load, DC energizing may cause overcurrent to flow through
the motor, thus burning the motor. To prevent this from occurring,
design a circuit in which a circuit breaker stops overcurrent to the
motor.
4. Hold-down Clips
Exercise care when pulling or inserting the hold-down clips so
that their form is not distorted. Do not use a clip that has already
been deformed. Otherwise excessive force will be applied to the
SSR, causing it not to perform to its specification, and also it will
not have enough holding power, causing the SSR to be loose,
and resulting in damage to the contacts.
5. PCB SSR Soldering
x SSRs must be soldered at 260°C within five seconds. For
models, however, that conform to separate conditions, perform
soldering according to the specified requirements.
x Use a rosin-based non-corrosive flux that is compatible with
the material of the SSR.
6. Ultrasonic Cleaning
Do not perform ultrasonic cleaning. Performing ultrasonic
cleaning after the SSR base has been installed will cause
ultrasonic waves to resonate throughout the SSR internal
structure, thereby damaging the internal components.

2. Short-circuit Protection
A short-circuit current or an overcurrent flowing through the load
of the SSR will damage the output element of the SSR. Connect
a quick-break fuse in series with the load as a short-circuit
protection measure.
Design a circuit so that the protection coordination conditions for
the quick-break fuse satisfy the relationship between the SSR
surge resistance (IS), quick-break fuse current-limiting feature
(IF), and the load inrush current (IL), shown in the following chart.

3. Operation Indicator
The operation indicator turns ON when current flows through the
input circuit. It does not indicate that the output element is ON.

Do not attempt to repair or use a terminal that has been
deformed. Otherwise excessive force will be applied to the SSR,
and it will lose its original performance capabilities.

Solid State Relays Common Precautions
■HANDLING THE SSR
■PCB-mounting SSRs
●Do Not Drop
1. Suitable PCBs
The SSR is a high-precision component. Do not drop the SSR or
subject it to excessive vibration or shock regardless of whether
the SSR is mounted or not.
The maximum vibration and shock that an SSR can withstand
varies with the model. Refer to the relevant datasheet.
The SSR cannot maintain its full performance capability if the
SSR is dropped or subjected to excessive vibration or shock.
In addition, it may result in malfunction due to its damaged
internal components if the SSR is dropped or subjected to
excessive vibration or shock.
The impact of shock given to the SSR that is dropped varies
upon the case. For example, if a single SSR is dropped on a
plastic tile from a height of 10 cm, the SSR may receive a shock
of 1,000 m/s2 or more. (It depends on the floor material, the
angle of collision with the floor, and the dropping height.)
Handle the SSR models in stick packages with the same care
and keep them free from excessive vibration or shock.
1 PCB Material
PCBs are classified into epoxy PCBs and phenol PCBs. The
following table lists the characteristics of these PCBs. Select
one, taking into account the application and cost. Epoxy PCBs
are recommended for SSR mounting in order to prevent the

2 PCB Thickness
The PCB may warp due to the size, mounting method, or
ambient operating temperature of the PCB or the weight of
components mounted to the PCB. Should warping occur, the
internal mechanism of the SSR on the PCB will be deformed
and the SSR may not provide its full capability. Determine the
thickness of the PCB by taking the material of the PCB into
consideration.

2. Mounting Space
The ambient temperature around the sections where the SSR is
mounted must be within the permissible ambient operating
temperature. If two or more SSRs are mounted closely together,
the SSRs may radiate excessive heat. Therefore, make sure that
the SSRs are separated from one another at the specified
distance provided in the datasheet. If there is no such
specification, maintain a space that is as wide as a single SSR.
Provide adequate ventilation to the SSRs as shown in the
following diagram.

Solid State Relays Common Precautions
3. Mounting SSR to PCB
Read the precautions for each model and fully
familiarize yourself with the following information
when mounting the SSR to the PCB.
Step 1
SSR mounting
Step 2
Flux coating
Flux
1. Do not bend the terminals to make the SSR
self-standing, otherwise the full
performance of the SSR may not be
possible.
2. Process the PCB properly according to the
mounting dimensions.
1. The flux must be a non-corrosive rosin flux,
which is suitable to the material of the SSR.
Apply alcohol solvent to dissolve the flux.
2. Make sure that all parts of the SSR other
than the terminals are free of the flux. The
insulation resistance of the SSR may be
degraded if there is flux on the bottom of
the SSR.
Step 5
Cooling
Step 6
Cleaning
1. After soldering the SSR, be sure to cool
down the SSR so that the soldering heat
will not deteriorate the SSR or any other
components.
2. Do not dip the SSR into cold liquid, such as
a detergent, immediately after soldering the
SSR.
1. Refer to the following table for the selection
of the cleaning method and detergent.
Detergent
Boiling or dip cleaning is possible for the SSR. Do
not perform ultrasonic cleaning or cut the
terminals, otherwise the internal parts of the SSR
may be damaged. Make sure that the temperature
of the detergent is within the permissible ambient
operating temperature of the SSR.
2. Applicability of Detergents

Note 1. Contact your OMRON representatives
before using any other detergent. Do not
apply Freon TMC, paint thinner, or gasoline
to any SSR.
Note 2. The space between the SSR and PCB may
be not be adequately cleaned with a
hydrocarbon or alcohol detergent.
●Automatic Soldering
1. Flow soldering is recommended for
maintaining a uniform soldering quality.
x Solder: JIS Z3282 or H63A
x Soldering temperature: Approx. 250°C
(Approx. 260°C for DWS)
x Soldering time: Approx. 5 s
(Approx. 2 s for first time and approx. 3 s for
second time for DWS)
x Perform solder level adjustments so that
the solder will not overflow on the PCB.
●Manual Soldering
1. After smoothing the tip of the soldering
iron, solder the SSR under the following
conditions.
x Solder: JIS Z3282,
1160A, or H63A with
rosin-flux-cored solder
Solder
Flux
x Soldering iron: 30 to 80 W
x Soldering temperature:
280°C to 350°C
x Soldering time: Approx. 3 s
2. As shown in the above illustration, solder
with a groove for preventing flux dispersion.
Actions are being taken worldwide to stop
the use of CFC-113 (chlorofluorocarbon)
and 1.1.1 trichloroethane. Your
understanding and cooperation are highly
appreciated.
Step 7
Coating
1. Do not fix the whole SSR with resin,
otherwise the characteristics of the SSR
may change.
2. The temperature of the coating material
must be within the permissible ambient
operating temperature range.

*
Note 1. The voltage between the load terminals of either SSR 1 or SSR
2 when turned OFF is approximately twice as high as the supply
voltage due to LC coupling. Be sure to use an SSR model with
a rated output voltage of at least twice the supply voltage.
For example, if the motor operates at a supply voltage of 100
VAC, the SSR must have an output voltage of 200 VAC or
higher.
Note 2. Make sure that there is a time lag of 30 ms or more to switch
over SW1 and SW2.
* Resistor to limit advanced phase capacitor discharge current.
To select a suitable resistor, consult with the manufacturer of the
motor.
