Note: The heat sink area refers to the combined area
of the sides of the heat sink that radiate heat.
For example, when a current of 18 A is allowed
to flow through the SSR at 40°C, the graph
shows that the heat sink area is about 450 cm2.
Therefore, if the heat sink is square, one side of
the heat sink must be 15 cm ( 450 (cm2)/2 ) or
longer.

Safety Precautions
!CAUTION
Touching the charged section may occasionally cause
minor electric shock. Do not touch the G3NA terminal
section (the charged section) when the power supply is
ON. Be sure to attach the cover before use.
The G3NA and heat sink will be hot and may occasionally
cause minor burns. Do not touch the G3NA 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 may
occasionally cause minor electric shock. Do not touch the
G3NA's main circuit terminals immediately after the
power is turned OFF.
• Abnormal heat generated by terminals may occasionally result
in fire damage. Do not operate if the screws on the output
terminal are loose.

• Abnormal heat generated by terminals may occasionally result
in fire damage. When tightening terminal screws, be sure that
no non-conductive foreign matter is caught in screw.
• For GN3A Relays of 40 A or higher, use crimp terminals of an
appropriate size for the wire diameter for M5 terminals.
Be sure to conduct wiring with the power supply turned
OFF, and always attach the terminal cover after
completing wiring. Touching the terminals when they are
charged may occasionally result in minor electric shock.
• Do not use any wires with damaged sheaths. These may cause
electric shock or leakage.
Do not apply a short-circuit to the load side of the G3NA.
The G3NA may rupture. To protect against short-circuit
accidents, install a protective device, such as a quickburning fuse, on the power supply line.
• Use wires of an appropriate length, otherwise malfunction and
damage may result due to induction.
■ Precautions for Safe Use
• Be sure that the G3NA clicks into place when mounting it to DIN
Track. The G3NA may fall if it is not mounted correctly.
Although OMRON continuously strives to improve the quality and
reliability of our relays, the G3NA contains semiconductors, which
are generally prone to occasional malfunction and failure.
Maintaining safety is particularly difficult if a relay is used outside of
its ratings. Always use the G3NA within the rated values. When using
the G3NA, always design the system to ensure safety and prevent
human accidents, fires, and social damage even in the event of
G3NA failure, including system redundancy, measures to prevent
fires from spreading, and designs to prevent malfunction.
1. G3NA malfunction or fire damage may occasionally occur. Do not
apply excessive voltage or current to the G3NA terminals.
2. Heat Dissipation
• Do not obstruct the airflow to the G3NA or heat sink. Heat
generated from an G3NA error may occasionally cause the
output element to short, or cause fire damage.
• Be sure to prevent the ambient temperature from rising due to
the heat radiation of the G3NA. If the G3NA is mounted inside a
panel, install a fan so that the interior of the panel is fully
ventilated.
• Mount the G3NA in the specified orientation. If the G3NA is
mounted in any other orientation, abnormal heat generation
may cause output elements to short or may cause burning.
• Do not use the G3NA if the heat sink fins are bent, e.g., as the
result of dropping the G3NA. Heat dissipation characteristics will
be reduced, possibly causing G3NA failure.
• Apply a thin layer of Momentive Performance Materials’s
YG6260 or Shin-Etsu Chemical’s G747, or a similar product to
the heat sink before mounting
• If a material with high thermal resistance, such as wood, is
used, heat generated by the G3NA may occasionally cause fire
or burning. When installing the G3NA directly into a control
panel so that the panel can be used as a heat sink, use a panel
material with low thermal resistance, such as aluminum or steel.
• Use the specified heat sink or one with equivalent or better
characteristics.
3. Wire the G3NA and tighten screws correctly, observing the
following precautions
Heat generated by a terminal error may occasionally result in fire
damage. Do not operate if the screws on the output terminal are
loose.
• Abnormal heat generated by wires may occasionally result in
fire damage. Use wires suitable for the load current.
12
Solid State Relays G3NA
• Do not place wiring in the same conduit or duct as high-voltage
lines. Induction may cause malfunction or damage.
• Mount the DIN Track securely. Otherwise, the DIN Track may
fall.
• Do not mount the G3NA when your hands are oily or dirty, e.g.,
with metal powder. These may cause G3NA failure.
• Tighten the G3NA screws securely.
Tightening torque: 0.78 to 0.98 Nºm
• Tighten the heat sink screws securely.
Tightening torque: 0.98 to 1.47 Nºm
4. Preventing Overheating
When using the High-capacity Heat Sink (Y92B-P250NF), always
use a thermostat or other method to protect from overheating in
the event that the fan stops.
5. Do Not Touch Fan Blades
When the fan is operating, do not touch the fan blades with any
part of your body or allow foreign matter to come into contact with
the blades. Always attach the enclosed finger guard when using
the G3NA.
6. Operating Conditions
• Only use the G3NA with loads that are within the rated values.
Using the G3NA with loads outside the rated values may result
in malfunction, damage, or burning.
• Use a power supply within the rated frequency range. Using a
power supply outside the rated frequency range may result in
malfunction, damage, or burning.
7. Do not transport the G3NA under the following conditions. Failure
or malfunction may occur.
• Conditions under which the G3NA will be exposed to water
• High temperatures or high humidity
• Without proper packing
Operating and Storage Locations

■ Precautions for Correct Use
Please observe the following precautions to prevent failure to
operate, malfunction, or undesirable effect on product performance.
Before Actual Operation
1. The G3NA in operation may cause an unexpected accident.
Therefore it is necessary to test the G3NA under the variety of
conditions that are possible. As for the characteristics of the
G3NA, it is necessary to consider differences in characteristics
between individual SSRs.
2. Unless otherwise specified, the ratings in this catalog are tested
values in a temperature range between 15C and 30C, a relative
humidity range between 25% and 85%, and an atmospheric
pressure range between 88 and 106 kPa (standard test
conditions according to JIS C5442). 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 G3NAs.
Mounting Method
SSR Mounting Pitch (Panel Mounting)
Duct
60 mm min.
Air inlet
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.
Do not locate any objects around the air inlet or air outlet, otherwise
the objects may obstruct the proper ventilation of the control panel.
A heat exchanger, if used, should be located in front of the SSRs to
ensure the efficiency of the heat exchanger.
• Please reduce the ambient temperature of SSRs.
The rated load current of an SSR is measured at an ambient
temperature of 40C.
• An SSR uses a semiconductor in the output element. This causes
the temperature inside the control panel to increase due to heating
resulting from the passage of electrical current through the load. To
restrict heating, attach a fan to the ventilation outlet or air inlet of
the control panel to ventilate the panel. This will reduce the ambient
temperature of the SSRs and thus increase reliability. (Generally,
each 10 C reduction in temperature will double the expected life.)

■ Precautions on Operating and Storage Environments
1. Operating Ambient Temperature
3. Vibration and Shock
The rated value for the ambient operating temperature of the G3NA
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
G3NA may exceed the rated value resulting in malfunction or
burning.
Do not subject the G3NA to excessive vibration or shock. Otherwise
the G3NA may malfunction and internal components may be
deformed or damaged, resulting in failure of the G3NA to operate.
When using the G3NA, 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
G3NA may increase as a result of environmental conditions (e.g.,
climate or air-conditioning) and operating conditions (e.g., mounting
in an airtight panel).
To prevent the G3NA from abnormal vibration, do not install the
G3NA in locations or by means that will subject it to vibration from
other devices, such as motors.
4. Solvents
Do not allow the G3NA or the resin portion of the Fan’s thermostat to
come in contact with solvents, such as thinners or gasoline. Doing so
will dissolve the markings on the G3NA.
2. Transportation
5. Oil
When transporting the G3NA, observe the following points. Not doing
so may result in damage, malfunction, or deterioration of
performance characteristics.
Do not allow the G3NA terminal cover to come in contact with oil.
Doing so will cause the cover to crack and become cloudy.
•
•
•
•
Do not drop the G3NA or subject it to severe vibration or shock.
Do not transport the G3NA if it is wet.
Do not transport the G3NA under high temperatures or humidity.
Do not transport the G3NA without packing it properly.
■ Operation
1. Leakage Current
2. Screw Tightening Torque
A leakage current flows through a snubber circuit in the G3NA even
when there is no power input. Therefore, always turn OFF the power
to the input or load and check that it is safe before replacing or wiring
the G3NA.
Tighten the G3NA terminal screws properly. If the screws are not
tight, the G3NA will be damaged by heat generated when the power
is ON. Perform wiring using the specified tightening torque.
3. Handling Relays
Varistor
Trigger circuit
Input circuit
Switch element Snubber circuit
Do not mount the G3NA when your hands are oily or dirty, e.g., with
metal powder. These may cause G3NA failure.
Leakage current
4. Do Not Drop
Be careful not to drop a Relay or Heat Sink onto any part of your
body while working. Injury may result. This is particularly true for the
High-capacity Heat Sink (Y92B-P250NF), which weighs 2.5 kg.
