3RV Motor Starter Protectors up to 100 A
General data
■ Overview
■ Application
Operating conditions
3RV1 motor starter protectors are suitable for use in any climate.
They are intended for use in enclosed rooms in which no severe
conditions (such as dust, caustic vapors, hazardous gases)
prevail. When installed in dusty and damp areas, suitable
enclosures must be provided.
3RV motor starter protectors can optionally be fed from the top
or from below.
The permissible ambient temperatures, the maximum switching
capacities, the tripping currents and other boundary conditions
can be found in the technical specifications and tripping
characteristics.
3RV1 motor starter protectors are suitable for use in IT systems
(IT networks). In this case, the different short-circuit breaking
capacity in the IT system must be taken into account.
S0 motor starter protectors

3RV1 motor starter protectors are compact, current limiting
motor starter protectors which are optimized for load feeders.
The motor starter protectors are used for switching and
protecting three-phase induction motors of up to 45 kW at
400 V AC and for other loads with rated currents of up to 100 A.
Type of construction
The motor starter protectors are available in four sizes:
• Size S00 – overall width 45 mm,
max. rated current 12 A,
at 400 V AC suitable for 3-phase induction motors
up to 5.5 kW.
• Size S0 – overall width 45 mm,
max. rated current 25 A,
at 400 V AC suitable for 3-phase induction motors
up to 11 kW.
• Size S2 – overall width 55 mm,
max. rated current 50 A,
at 400 V AC suitable for 3-phase induction motors
up to 22 kW.
• Size S3 – overall width 70 mm,
max. rated current 100 A,
at 400 V AC suitable for 3-phase induction motors
up to 45 kW.

Siemens LV 1 · 2006
Since operational currents, starting currents and current peaks
are different even for motors with identical power ratings due to
the inrush current, the motor ratings in the selection tables are
only guide values. The specific rated and start-up data of the
motor to be protected is always paramount to the choice of the
most suitable motor starter protector. This also applies to motor
starter protectors for transformer protection.
Possible uses
The 3RV1 motor starter protectors can be used:
• For short-circuit protection
• For motor protection (also with overload relay function)
• For plant protection
• For short-circuit protection for starter combinations
• For transformer protection
• As main control and EMERGENCY-STOP switches
• For fuse monitoring
• For use in IT systems (IT networks)
• For switching of DC currents
• As voltage transformer circuit-breakers
More information is available under "Configuration".

■ Overview
Mounting location and function
The 3RV1 motor starter protectors have three main contact
elements. In order to achieve maximum flexibility, auxiliary
switches, alarm switches, auxiliary releases and isolator
modules can be supplied separately.
Front
Transverse auxiliary switches
Notes:
1 NO + 1 NC
These components can be fitted as required on the motor starter
protectors without using tools.
An auxiliary contact block can be inserted transversely on the front.
The overall width of the motor starter protectors remains unchanged.
• A maximum of 4 auxiliary
or
contacts with auxiliary switches 2 NO
can be attached to each motor
or 1 changeover contact
starter protector.
• Transverse auxiliary switches
must not be used for the 3RV17
motor starter protectors.
Left-hand side
Lateral auxiliary switches
(2 contacts)
1 NO + 1 NC
or
2 NO
or
2 NC
Lateral auxiliary switches
(4 contacts)
2 NO + 2 NC
One of the three auxiliary switches can be mounted laterally for each motor starter
protector. The contacts of the auxiliary switch close and open together with the main
contacts of the motor starter protector.
The overall width of the lateral auxiliary switch with 2 contacts is 9 mm.
One auxiliary switch can be mounted laterally for each motor starter protector. The
contacts of the auxiliary switch close and open together with the main contacts of the
motor starter protector.
The overall width of the lateral auxiliary switch with 4 contacts is 18 mm.
Alarm switches for sizes S0, S2, One alarm switch can be mounted at the side of each motor starter protector with a
and S3
rotary operating mechanism.
5
Notes:
• Auxiliary switches (2 contacts)
Trip 1 NO + 1 NC
and alarm switches can be
mounted separately or together. Short-circuit 1 NO + 1 NC
• A maximum of 4 auxiliary
contacts with auxiliary switches
can be attached to each motor
starter protector.
The alarm switch has two contact systems.
One contact system always signals tripping irrespective of whether this was caused by
a short-circuit, an overload or an auxiliary release. The other contact system only
switches in the event of a short-circuit. There is no signaling as a result of switching off
with the handle.
In order to be able to switch on the motor starter protector again after a short-circuit, the
alarm switch must be reset manually after the error cause has been eliminated.
The overall width of the alarm switch is 18 mm.
Right-hand side
Shunt release
For remote-controlled tripping of the motor starter protector. The release coil should
only be energized for short periods (see schematics).
or
Undervoltage release
Trips the motor starter protector when the voltage is interrupted and prevents the motor
from being restarted accidentally when the voltage is restored. Used for remotecontrolled tripping of the motor starter protector.
Particularly suitable for EMERGENCY-STOP disconnection by way of the corresponding
EMERGENCY-STOP button according to DIN VDE 0113.
or
Notes:
• One auxiliary release can be
mounted per motor starter
protector.
Undervoltage release with
leading auxiliary contacts
(2 NO)
• Accessories cannot be mounted
at the right-hand side of the
3RV11 motor starter protectors
with overload relay function.
Top
Note:
The overall width of the auxiliary release is 18 mm.
Isolator modules for
motor starter protectors
The isolator module covers the Size S0 and S2
terminal screws of the
transverse auxiliary switch. If
the isolator module is used, we
therefore recommend that
either the lateral auxiliary
switches be fitted or that the
isolator module not be mounted
until the auxiliary switch has
been wired.
5/14
Function and use as for the undervoltage release without leading auxiliary contacts, but
with the following additional function: the auxiliary contacts will open in switch position
OFF to deenergize the coil of the undervoltage release, thus interrupting power
consumption. In the "tripped" position, these auxiliary contacts are not guaranteed to
open. The leading contacts permit the motor starter protector to reclose.
Siemens LV 1 · 2006
Isolator modules can be mounted to the upper terminal end of motor starter protectors
of sizes S0 and S2.
The supply cable is connected to the motor starter protector through the isolator
module.
The plug can only be unplugged when the motor starter protector is open and isolates
all 3 poles of the motor starter protector from the network. The shock-protected isolation
point is clearly visible and secured with a padlock to prevent reinsertion of the plug.

■ Overview
Insulated three-phase busbar systems
Three-phase busbar systems provide an easy, time-saving and
clearly arranged means of feeding 3RV1 motor starter protectors
with screw-type terminals. Different designs are available for
sizes S00, S0 and S2 and can be used for the various different
types of motor starter protectors. The only exceptions are the
3RV19 15 three-phase busbar systems, which are not suitable
for the 3RV11 motor starter protectors with overload relay
function.
The busbars are suitable for between 2 and 5 motor starter
protectors. However, any kind of extension is possible by
clamping the tags of an additional busbar (rotated by 180°)
underneath the terminals of the respective last motor starter
protector.
Busbars with larger modular spacing can be used for motor
starter protectors with laterally mounted accessories.
The motor starter protectors are supplied by appropriate lineside terminals.
3-phase busbar system, with example for combining sizes S00 and S0
Busbar adapters
The motor starter protectors are mounted directly with the aid of
busbar adapters on busbar systems with 40 mm and 60 mm
center-line spacing in order to save space and to reduce infeed
times and costs.
The three-phase busbar systems are finger-safe. They are
designed for any short-circuit stress which can occur at the load
side of connected motor starter protectors.
Busbar adapters for busbar systems with 40 mm center-line
spacing are suitable for copper busbars with a width of 12 mm
to 15 mm, while those with 60 mm center-line spacing are
suitable for copper busbars with a width of 12 mm to 30 mm.
The busbars can be 4 to 5 mm or 10 mm thick.
The three-phase busbar systems can also be used to construct
"Type E Starters" of size S0 or S2 according to UL/CSA. Special
feeder terminals must be used for this purpose, however (see
Selection and Ordering Data).
The motor starter protectors are snapped onto the adapter and
connected on the line side. This prepared unit is then plugged
directly onto the busbar system, and is thus connected both
mechanically and electrically at the same time.
3RV19 35-5A
Further busbar adapters for snap-mounting direct-on-line
starters and reversing starters as well as additional accessories
such as line terminals and outgoing terminals, busbar copper,
etc., can be found under "Distribution/Busbar Systems and
Controlgear".

Rotary operating mechanisms
■ Overview
Door-coupling rotary operating mechanisms
Motor starter protectors with a rotary operating mechanism can
be mounted in a control cabinet and operated externally by
means of a door-coupling rotary operating mechanism. When
the cabinet door with motor starter protector is closed, the
operating mechanism is coupled. When the motor starter
protector closes, the coupling is locked which prevents the door
from being opened unintentionally. This lock can be defeated by
the maintenance personnel. In the Open position, the rotary
operating mechanism can be secured against reclosing with up
to 3 padlocks. Inadvertent opening of the door is not possible in
this case either.
Remote motorized operating mechanisms
3RV1 motor starter protectors are manually operated controls.
They automatically trip in case of an overload or short-circuit.
Intentional remote-controlled tripping is possible by means of a
shunt release or an undervoltage release. Reclosing is only
possible directly at the motor starter protector.
The remote motorized operating mechanism allows the motor
starter protectors to be opened and closed by electrical
commands. This enables a load or an installation to be isolated
from the power system or reconnected to it from an operator
panel.
NSB01078
If the motor starter protector is tripped as a result of overload or
short-circuit, it will be in tripped position. For reclosing, the
remote motorized operating mechanism must first be set
manually or electrically to the 0 position (electrically by means of
the Open command). Then it can be reclosed.
The remote motorized operating mechanism is available for
motor starter protectors of size S2 (Inmax = 50 A) and S3
(Inmax = 100 A) that are designed for control voltages of
230 V AC and 24 V DC. The motor starter protector is fitted into
the remote motorized operating mechanism as shown in the
drawing.
5
In the "MANUAL" position, the motor starter protector in the
remote motorized operating mechanism can continue to be
switched manually on site. In the "AUTOMATIC" position, the
motor starter protector is switched by means of electrical
commands. The switching command must be applied for a
minimum of 100 ms. The remote motorized operating
mechanism closes the motor starter protector after a maximum
of 1 second. On voltage failure during the switching operation it
is ensured that the motor starter protector remains in the Open
or Closed position.

Door-coupling rotary operating mechanisms
The door-coupling rotary operating mechanisms consist of a knob, a coupling driver and an extension shaft of 130/330 mm in
length (5 x 5 mm). The door-coupling rotary operating mechanisms are designed to the degree of protection IP65. The door
locking device prevents accidental opening of the control cabinet door in the ON position of the motor starter protector. The OFF
position can be locked with up to 3 padlocks.

The door-coupling rotary operating mechanisms consist of a knob, a coupling driver, an extension shaft of 300 mm in length
(8 x 8 mm), a spacer and two metal brackets, into which the motor starter protector is inserted. The door-coupling rotary operating
mechanisms are designed to degree of protection IP65. The door locking device reliably prevents opening of the control cabinet
door in the ON position of the circuit-breaker. The OFF position can be locked with up to 3 padlocks. Laterally mountable auxiliary
releases and two-pole auxiliary switches can be used. The door-coupling rotary operating mechanism thus meets the
requirements for isolating functions to IEC 60947-2.

■ Overview
Enclosures
For installing motor starter protectors of sizes S00 (Inmax = 12 A),
S0 (Inmax = 25 A) and S2 (Inmax = 50 A) as a single unit, moldedplastic enclosures for surface mounting and molded-plastic
enclosures for flush mounting are available in various
dimensions.
When installed in a molded-plastic enclosure the motor starter
protectors have a rated operational voltage Ue of 500 V
The enclosures for surface mounting have the degree of
protection IP55; the enclosures for flush mounting also comply
with the degree of protection IP55 at the front (the flush-mounted
section complies with IP20).
by using a special key. The motor starter protector can
subsequently be switched on again.
The molded-plastic enclosures of S0 and S2 motor starter
protectors with rotary operating mechanism are fitted with a
rotary operating mechanism as well.
The enclosures can be supplied with a black rotary operating
mechanism or with an EMERGENCY-STOP rotary operating
mechanism with a red/yellow knob.
All rotary operating mechanisms can be locked in the Open
position with up to 3 padlocks.
Front plates
The front plates for size S00 have a retaining frame into which the
motor starter protectors can be snapped. A retaining frame for
size S0 motor starter protectors is available for front plate sizes
S0 to S3.

NSB01080
Motor starter protectors are frequently required to be actuated in
any enclosure. Front plates equipped with an actuating
diaphragm for size S00 motor starter protectors, or rotary
operating mechanism for S0 to S3 motor starter protectors are
available for this purpose.
NSB01081
Enclosure for surface mounting
Front plate for size S00
Accessories for enclosures and front plates
Enclosure for flush mounting
All enclosures are equipped with N and PE/ground terminals.
There are two knock-out cable entries for cable glands at the top
and two at the bottom; also on the rear corresponding cable
entries are scored. There is a knock-out on the top of the
enclosure for indicator lights that are available as accessories.
The narrow enclosure can accommodate a motor starter
protector without accessories, with transverse and lateral
auxiliary switch, whereas wide enclosures and enclosures for S2
motor starter protectors also provide space for a laterally
mounted auxiliary release. There is no provision for installing a
motor starter protector with an alarm switch.
With S00 motor starter protectors, the switch rocker is operated
by means of the actuator diaphragm of the enclosure. A locking
device, capable of holding up to three padlocks, can be fitted
onto the actuator diaphragm to prevent the motor starter
protector from closing during maintenance work, for example.
A mushroom-shaped EMERGENCY-STOP knob can be fitted in
place of the locking device. If it is actuated abruptly, the motor
starter protector opens and the mushroom-shaped knob
latches. The knob can be unlatched again either by turning it or

Overload Relays
3RB2 Solid-State Overload Relays
3RB20, 3RB21 for standard applications
■ Overview
The 3RB20 and 3RB21 solid-state overload relays up to 630 A
with internal power supply have been designed for currentdependent protection of loads with normal and heavy starting
(see LV 1 T, Function) against excessive temperature rises due
to overload, phase unbalance or phase failure. An overload,
phase unbalance or phase failure result in an increase of the
motor current beyond the set motor rated current. This current
rise is detected by the current transformers integrated into the
devices and evaluated by corresponding solid-state circuits
which then output a pulse to the auxiliary contacts. The auxiliary
contacts then switch off the load by means of a contactor. The
break time depends on the ratio between the tripping current
and set current Ie and is stored in the form of a long-term stable
tripping characteristic (see LV 1 T, Characteristic Curves).
The "tripped" status is signaled by means of a switch position
indicator (see LV 1 T, Function). Resetting takes place either
manually or automatically after the recovery time has elapsed
(see LV 1 T, Function).
The devices are manufactured in accordance with
environmental guidelines and contain environmentally friendly
and reusable materials. They comply with all important
worldwide standards and approvals.
■ Benefits
The most important features and benefits of the 3RB20/3RB21
solid-state overload relays are listed in the overview table
(see Overload Relays, General Data).
Siemens LV 1 · 2006

(1) Connection for mounting onto contactors:
Optimally adapted in electrical, mechanical and design terms to the
contactors and soft starters, these connecting pins can be used for
direct mounting of the overload relays. Stand-alone installation is
possible as an alternative (in some cases in conjunction with a standalone installation module).
(2) Selector switch for manual/automatic RESET and RESET button:
With the slide switch you can choose between manual and automatic
RESET. A device set to manual RESET can be reset locally by pressing
the RESET button. On the 3RB21 a solid-state remote RESET is
integrated.
(3) Switch position indicator and TEST function of the wiring:
Indicates a trip and enables the wiring test.
(4) Solid-state test:
Enables a test of all important device components and functions.
(5) Motor current setting:
Setting the device to the rated motor current is easy with the large
rotary knob.
(6) Trip class setting/internal ground-fault detection (only 3RB21):
Using the rotary switch you can set the required trip class and activate
the internal ground-fault detection dependent on the starting
conditions.
(7) Connecting terminals (removable terminal block for auxiliary circuits):
The generously sized terminals permit connection of two conductors
with different cross-sections for the main and auxiliary circuits. The
auxiliary circuit can be connected with screw-type terminals and
alternatively with spring-loaded terminals.
In addition to current-dependent protection of loads against
excessive temperature rises due to overload, phase unbalance
and phase failure, the 3RB21 solid-state overload relays also
allow internal ground-fault detection (not possible in conjunction
with wye-delta assemblies). This provides protection of loads
against high-resistance short-circuits due to damage to the
insulation material, moisture, condensed water etc.
Overload Relays
3RB2 Solid-State Overload Relays
3RB20, 3RB21 for standard applications
■ Application
Industries
The 3RB20/3RB21 solid-state overload relays are suitable for
customers from all industries who want to guarantee optimum
inverse-time delayed protection of their electrical loads
(e.g. motors) under normal and heavy starting conditions
(CLASS 5 to CLASS 30), minimize project completion times,
inventories and power consumption, and optimize plant
availability and maintenance management.
Application
The 3RB20/3RB21 solid-state overload relays have been
designed for the protection of three-phase motors in sinusoidal
50/60 Hz voltage networks. The relays are not suitable for the
protection of single-phase AC or DC loads.
The 3RU11 thermal overload relay or the 3RB22/3RB23 solidstate overload relay can be used for single-phase AC loads.
For DC loads we recommend the 3RU11 thermal overload relay.
Ambient conditions
The devices are insensitive to external influences such as
shocks, corrosive environments, ageing and temperature
changes.
5
For the temperature range from –25 C to +60 °C, the
3RB20/3RB21 solid-state overload relays compensate the
temperature according to IEC 60947-4-1.
Configuration notes for use of the devices below –25 °C or above
+60 °C on request.

supply type 3RB22 (with monostable auxiliary contacts) and
type 3RB23 (with bistable auxiliary contacts) up to 630 A (up to
820 A possible with a series transformer) have been designed
for inverse-time delayed protection of loads with normal and
heavy starting (see LV 1 T, Function) against excessive
temperature rises due to overload, phase unbalance or phase
failure. An overload, phase unbalance or phase failure result in
an increase of the motor current beyond the set motor rated
current. This current rise is detected by means of a current
measuring module and electronically evaluated by a special
evaluation module which is connected to it. The evaluation
electronics sends a signal to the auxiliary contacts. The auxiliary
contacts then switch off the load by means of a contactor. The
break time depends on the ratio between the tripping current
and set current Ie and is stored in the form of a long-term stable
tripping characteristic (see LV 1 T, Characteristic Curves). The
"tripped" status is signaled by means of a continuous red
"Overload" LED.
3RB22/3RB23 evaluation module
(1) Green "Ready" LED
A continuous green light signals that the device is working correctly.
(2) Red "Ground fault" LED:
A continuous red light signals a ground fault.
(3) Red "Thermistor" LED:
A continuous red light signals an active thermistor trip.
(4) Red "Overload" LED:
A continuous red light signals an active overload trip; a flickering red
light signals an imminent trip (overload warning).
(5) Motor current and trip class adjustment:
Setting the device to the motor current and to the required trip class
dependent on the starting conditions is easy with the two rotary knobs.
(6) Selector switch for manual/automatic RESET:
With this switch you can choose between manual and automatic
RESET.
(7) Test/RESET button:
Enables testing of all important device components and functions,
plus resetting of the device after a trip when manual RESET is
selected.
(8) Connecting terminals (removable terminal block):
The generously sized terminals permit connection of two conductors
with different cross-sections for the auxiliary, control and sensor
circuits. Connection is possible with screw-type terminals and
alternatively with spring-loaded terminals.
(9) 3RB29 85 function expansion module:
Enables more functions to be added, e.g. internal ground fault
detection and/or an analog output with corresponding signals.
The LED indicates imminent tripping of the relay due to overload,
phase unbalance or phase failure by flickering when the limit
current has been violated. This warning can also issued as a
signal through auxiliary contacts.
In addition to the described inverse-time delayed protection of
loads against excessive temperature rises, the 3RB22/3RB23
solid-state overload relays also allow direct temperature monitoring of the motor windings (full motor protection) by failsafe
connection of a PTC sensor circuit. With this temperature-dependent protection, the loads can be protected against overheating
caused indirectly by reduced coolant flow, for example, which
cannot be detected by means of the current alone. In the event
of overheating, the devices switch off the contactor, and thus the
load, by means of the auxiliary contacts. The "tripped" status is
signaled by means of a continuously illuminated "Overload" LED.
To also protect the loads against high-resistance short-circuits
due to damage to the insulation, humidity, condensed water,
etc., the 3RB22/3RB23 solid-state overload relays offer the
possibility of internal ground fault monitoring in conjunction with
a function expansion module (for details see Selection and
Ordering Data; not possible in conjunction with contactor
assembly for Wye-Delta starting). In the event of a ground fault
the 3RB22/3RB23 relays trip instantaneously. The "tripped"
status is signaled by means of a red "Ground Fault" LED.
Signaling through auxiliary contacts is also possible.
After tripping due to overload, phase unbalance, phase failure,
thermistor tripping or ground fault, the relay is reset manually or
automatically after the recovery time has elapsed (see LV 1 T,
Function).
In conjunction with a function expansion module the motor
current measured by the microprocessor can be output in the
form of an analog signal 4 ... 20 mA DC for operating rotary coil
instruments or for feeding into analog inputs of programmable
logic controllers. With an additional AS-Interface analog module
the current values can also be transferred over the
AS-i bus system.
The devices are manufactured in accordance with environmental guidelines and contain environmentally friendly and reusable
materials.
They comply with all important worldwide standards and
approvals.

Overload Relays
3RU1 Thermal Overload Relays
3RU11 for standard applications
■ Overview
■ Benefits
The most important features and benefits of the 3RU11 thermal
overload relays are listed in the overview table (see Overload
Relays, General Data).
■ Application
Industries
The 3RU11 thermal overload relays are suitable for customers
from all industries who want to guarantee optimum inverse-time
delayed protection of their electrical loads (e.g. motors) under
normal starting conditions (CLASS 10).
Application
The 3RU11 thermal overload relays have been designed for the
protection of three-phase and single-phase AC and DC motors.
The 3RU11 thermal overload relays up to 100 A have been
designed for current-dependent protection of loads with normal
starting (see LV 1 T, Function) against excessive temperature
rises due to overload or phase failure. An overload or phase
failure results in an increase of the motor current beyond the set
motor rated current. Via heating elements, this current rise heats
up the bimetal strips inside the device, which then bend and as
a result trigger the auxiliary contacts by means of a tripping
mechanism. The auxiliary contacts then switch off the load by
means of a contactor. The break time depends on the ratio
between the tripping current and set current Ie and is stored in
the form of a long-term stable tripping characteristic (see LV 1 T,
Characteristic Curves).
Ambient conditions
The 3RU11 thermal overload relays have temperature
compensation in accordance with IEC 60947-4-1 for the
temperature range of –20 to +60 °C. For temperatures from
+60 to +80 °C the upper setpoint value of the setting range must
be reduced by the factor listed in the table below.

"Increased safety" type of protection EEx e according to
ATEX guideline 94/9/EC
The 3RU11 thermal overload relays are suitable for the overload
protection of explosion-proof motors with "increased safety" type
of protection EEx e. The relays meet the requirements of
EN 60079-7 (Electrical apparatus for potentially explosive
atmospheres – Increased safety "e").
The basic safety and health requirements of ATEX guideline
94/9/EG are fulfilled by compliance with
• EN 60947-4-1
• EN 60947-5-1
• EN 60079-14: 1997-02
• EN 60079-17: 1996-12
EU type test certificate for Category (2) G/D exists. It has the
number DMT 98 ATEX 6001.
The "tripped" status is signaled by means of a switch position
indicator (see LV 1 T, Function). Resetting takes place either
manually or automatically after the recovery time has elapsed
(see LV 1 T, Function).
The devices are manufactured in accordance with
environmental guidelines and contain environmentally friendly
and reusable materials.
They comply with all important worldwide standards and
approvals.
Siemens LV 1 · 2006

(1) Connection for mounting onto contactors:
Optimally adapted in electrical, mechanical and design terms to the
contactors, these connecting pins can be used for direct mounting of
the overload relays. Stand-alone installation is possible as an
alternative (in some cases in conjunction with a stand-alone
installation module).
(2) Selector switch for manual/automatic RESET and RESET button:
With this switch you can choose between manual and automatic
RESET. A device set to manual RESET can be reset locally by pressing
the RESET button. A remote RESET is possible using the RESET
modules (accessories), which are independent of size.
(3) Switch position indicator and TEST function of the wiring:
Indicates a trip and enables the wiring test.
(4) Motor current setting:
Setting the device to the rated motor current is easy with the large
rotary knob.
(5) STOP button:
If the STOP button is pressed, the NC contact is opened. This switches
off the contactor downstream. The contactor is switched on again
when the STOP button is released.
(6) Transparent, sealable cover:
Secures the motor current setting, TEST function and the selector
switch for manual/automatic RESET against adjustment.
(7) Supply terminals:
The generously sized terminals permit connection of two conductors
with different cross-sections for the main and auxiliary circuits. The
auxiliary circuit can be connected with screw-type terminals and
alternatively with spring-loaded terminals.
If single-phase AC or DC loads are to be protected by the 3RU11
thermal overload relays, all three bimetal strips must be heated.
For this purpose, all main circuits of the relay must be connected
in series.
