"Increased safety" type of protection EEx e according to
ATEX directive 94/9/EC
The 3RV20 motor starter protectors are suitable for the overload
protection of explosion-proof motors with "increased safety" type
of protection EEx e; see Chapter 9 "Appendix" --> "Standards
and Approvals" --> "Type Overview of Approved Devices for
Explosion-Protected Areas (ATEX Explosion Protection)".
SIRIUS 3RV2 Motor Starter Protectors/Circuit Breakers up to 40 A
General data
■ Application
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.
Operating conditions
3RV2 motor starter protectors are suitable for use in any climate.
They are intended for use in enclosed rooms in which no severe
operating conditions (such as dust, caustic vapors, hazardous
gases) prevail. When installed in dusty and damp areas, suitable
enclosures must be provided.
Possible uses
The 3RV2 motor starter protectors can be used:
• For short-circuit protection
• For motor protection (also with overload relay function)
• For system protection
• For short-circuit protection for starter combinations
• For transformer protection
• As main and EMERGENCY-STOP switches
• For operation in IT systems (IT networks)
• For switching of DC currents
• In areas subject to explosion hazard (ATEX)
3RV2 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, see note on Technical Information on page 5/1.
3RV2 motor starter protectors are suitable for operation in IT
systems (IT networks). In this case, the different short-circuit
breaking capacity in the IT system must be taken into account.
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
For more information see the note on Technical Information on
page 5/1.

SIRIUS Innovations Supplement 2012Overview
Mounting location and function
The 3RV2 motor starter protectors have three main contact
elements. In order to achieve maximum flexibility, auxiliary
switches, signaling switches, auxiliary releases, and isolator
modules can be supplied separately.
These components can be fitted on the motor starter protectors
without using tools.
Front side
An auxiliary switch block can be inserted transversely on the front. The
overall width of the motor starter protectors remains unchanged.
A maximum of 4 auxiliary contacts with
auxiliary switches can be attached per
motor starter protector.

(4 contacts)
The signaling switch cannot be used for the
3RV27 and 3RV28 motor starter protectors/ 2 NO + 2 NC
circuit breakers.
Signaling switch
Tripping 1 NO + 1 NC
Short-circuit 1 NO + 1 NC
One of the three lateral auxiliary switches can be mounted on the left side
per 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 lateral auxiliary switch with four contacts can be mounted on the left
side per 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.
One signaling switch can be mounted on the left side of each motor starter
protector.
The signaling 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 signaling switch must be reset manually after the error
cause has been eliminated.
The overall width of the signaling switch is 18 mm.
Right-hand side
Auxiliary releases
Notes:
Shunt releases
One auxiliary release can be mounted
per motor starter protector.
Accessories cannot be mounted
at the right-hand side of the 3RV21 motor
starter protectors
for motor protection with overload relay
function.
For remote-controlled tripping of the motor starter protector. The release coil
should only be energized for short periods (see schematics).
or
Undervoltage releases
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 remote-controlled tripping of the motor starter protector.
Particularly suitable for EMERGENCY-STOP disconnection by way of the
corresponding EMERGENCY-STOP pushbutton according to
EN 60204-1 (VDE 0113).
or
Undervoltage releases with
leading auxiliary contacts 2 NO
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 energy consumption. In the "tripped" position,
these auxiliary contacts are not guaranteed to open. The leading contacts
permit the motor starter protector to reclose.
The overall width of the auxiliary release is 18 mm.
Top
Isolator modules
Notes:
The isolator module cannot be used
for the 3RV27 and 3RV28 motor starter
protectors/circuit breakers.
The isolator module covers the 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.
Isolator modules can be mounted to the upper terminal end of the motor
starter protectors.
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.
For a complete overview of which accessories can be used
for the various motor starter protectors see page 5/2.

SIRIUS 3RV2 Motor Starter Protectors/Circuit Breakers up to 40 A
Accessories
Busbar accessories
Insulated three-phase busbar systems
8US Fast Bus busbar adapters for 60 mm systems
Three-phase busbar systems provide an easy, time-saving and
clearly arranged means of feeding 3RV2 motor starter protectors
with screw terminals. They can be used for the different types of
motor starter protector up to 32 A. The 3RV19 15 three-phase
busbar systems are generally unsuitable for the 3RV21 motor
starter protectors for motor protection with overload relay function and for the 3RV27 and 3RV28 circuit breakers according to
UL 489 / CSA C22.2 No.5-02.
The motor starter protectors are mounted directly with the aid of
busbar adapters on busbar systems with 60 mm center-tocenter clearance in order to save space and to reduce infeed
times and costs.
The busbars are suitable for between 2 and 5 circuit breakers/
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.
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.
A combination of motor starter protectors of sizes S00 and S0 is
possible. The motor starter protectors are supplied by
appropriate feeder terminals.
The busbar adapters for busbar systems with 60 mm center-tocenter clearance are suitable for copper busbars with a width of
12 to 30 mm. The busbars can be 5 mm or 10 mm thick.
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, flat copper profile,
etc., can be found in the Controls catalog, Chapter 5 "8US Fast
Bus Busbar Systems".

Three-phase busbar system size S00/S0
The three-phase busbar systems are finger-safe. They are
designed for any short-circuit stress which can occur at the output side of connected motor starter protectors.
The three-phase busbar systems can also be used to construct
"Type E Starters" according to UL/CSA. Special feeder terminals
must be used for this purpose, however (see "Selection and
ordering data").

3RV29 infeed system
Overview
The 3RV29 infeed system is a convenient means of energy
supply and distribution for a group of several motor starter
protectors or complete motor starters with a screw or springtype connection in sizes S00 and S0 (exception: this system
cannot be used for the 3RV21, 3RV27 and 3RV28 motor starter
protectors/circuit breakers).
The electrical connection between the three-phase busbars and
the motor starter protectors is implemented through plug-in
connectors. The complete system can be mounted on a TH 35
standard mounting rail to EN 60715 and can be expanded as
required up to a maximum current carrying capacity of 63 A.
The system is mounted extremely quickly and easily thanks to
the simple plug-in technique. Thanks to the lateral infeed, the
system also saves space in the control cabinet. The additional
overall height required for the infeed unit is only 30 mm. The
alternative infeed possibilities on each side offer a high degree
of flexibility for configuring the control cabinet: Infeed on lefthand or right-hand side as well as infeed on one side and outfeed on the other side to supply further loads are all possible. A
terminal block with spring-type connections in combination with
a standard mounting rail enables the integration of not only
SIRIUS motor starter protectors but also single-phase, 2-phase
and 3-phase components such as 5SY miniature circuit breakers
or SIRIUS relay components.
The system is based on a basic module complete with a lateral
incoming unit (three-phase busbar with infeed). This infeed with
spring-type terminals is mounted on the right or left depending
on the version and can be supplied with a maximum conductor
cross-section of 25 mm2 (with end sleeve). A basic module has
two sockets onto each of which a motor starter protector can be
snapped.
Expansion modules are available for extending the system
(three-phase busbars for system expansion). The individual
modules are connected through an expansion plug.

$ Three-phase busbars with infeed
* Contactor base
A three-phase busbar with infeed unit is required for connecting
the energy supply. This module comprises one infeed module
and 2 sockets which each accept one motor starter protector. A
choice of two versions with infeed on the left or right is available.
The infeed is connected using spring-type terminals. The
spring-type terminals permit conductor cross-sections of up to
25 mm2 with end sleeves. An end cover is supplied with each
module.
Motor starters can be assembled in the system using the contactor base. The contactor bases are suitable for contactors sizes
S00 and S0 with spring-type and screw terminals and are simply
snapped onto the three-phase busbars. Direct-on-line starters
and reversing starters are possible. One contactor base is required for direct-on-line starters and two are required for reversing starters.
% Three-phase busbars for system expansion
The three-phase busbars for system expansion allow the system
to be expanded. There is a choice of modules with 2 or 3 sockets. The system can be expanded as required up to a maximum
current carrying capacity of 63 A. An expansion plug is supplied
with each module.
&a Expansion plug
The expansion plug is used for electrical connection of adjacent
three-phase busbars. The current carrying capacity of this plug
equals 63 A. One expansion plug is supplied with each threephase busbar for system expansion. Additional expansion plugs
are therefore only required as spare parts.
5
&b Extra-wide expansion plug
The wide expansion plug makes the electrical connection between two three-phase busbars, thus performing the same function as the 3RV29 17-5BA00 expansion plug; the electrical characteristics (e.g. a current carrying capacity of 63 A) are
identical.
The 3RV29 17-5E expansion plug is 10 mm wider than the
3RV29 17-5BA00 expansion plug, hence in the plugged state
there is a distance of 10 mm between the connected threephase busbars. This distance can be used to lay the auxiliary
current and control current wiring ("wiring duct"). The motor
starter protector and contactor can be wired from underneath,
which means that the complete cable duct above the system
can be omitted.
( End cover
The end cover is used to cover the three-phase busbar at the
open end of the system. This cover is therefore only required
once for each system. An end cover is supplied with each threephase busbar system with infeed. Further end covers are therefore only required as spare parts.
) Plug-in connector
The plug-in connector is used for the electrical connection between the three-phase busbar and the 3RV2 motor starter protector. These plug-in connectors are available in versions for
screw or spring-type terminals.
5/26
SIRIUS Innovations Supplement 2012
To assemble motor starters for reversing starters, the contactor
bases can be arranged alongside each other (90 mm overall
width). In this case the mechanical interlocking of the contactors
is possible. The contactor bases are also suitable for soft starters size S00 and S0 with screw connection.
The infeed system is designed for mounting on a 35 mm standard mounting rail with 7.5 mm overall depth. This standard
mounting rail gives the contactor base a stable mounting surface to sit on. If standard mounting rails with a depth of 15 mm
are used, the spacer connected to the bottom of the contactor
base must be knocked out and plugged into the mating piece
that is also on the underside. Then the contactor base also has
a stable mounting surface. When standard mounting rails with a
depth of 7.5 mm are used, the spacer has no function and can
be removed.
The link modules are used for direct start motor starters, in which
case the use of a contactor base is not absolutely necessary.
Motor starter protector and contactor assemblies can then be directly snapped onto the sockets of the three-phase busbars. For
starters of size S00 and S0, the corresponding 3RA19 21-1....,
3RA29 11-2...., 3RA29 21-1.... or 3RA29 21-2.... link modules
should generally be used.
+ Terminal block
The 3RV29 17-5D terminal block enables the integration of not
only SIRIUS motor starter protectors but also single-phase,
2-phase and 3-phase components. Using the terminal block the
3 phases can be fed out of the system; which means that singlephase loads can also be integrated in the system. The terminal
block is plugged into the slot of the expansion plug and thus enables outfeeding from the middle or end of the infeed system.
The terminal block can be rotated through 180° and be locked
to the support modules of the infeed system. The 3RV19 17-7B
45 mm standard mounting rail for screwing onto the support
plate is available in addition in order to be able to plug the single-phase, 2-phase and 3-phase components onto the infeed
system.

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 interlock can be disengaged 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.

Door-coupling rotary operating mechanisms for arduous conditions
The door-coupling rotary operating mechanisms consist of a knob, a coupling driver, an extension shaft of 300 mm in length
(8 mm 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 interlocking reliably prevents
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.
Laterally mountable auxiliary releases and two-pole auxiliary switches can be used.
The door-coupling rotary operating mechanisms thus meet the requirements for isolating functions according to IEC 60947-2.

■ Overview
Accessories for "Self-Protected Combination Motor
Controllers (Type E)" according to UL 508
The 3RV20 motor starter protectors are approved according to
UL 508 as "Self-Protected Combination Motor Controllers
(Type E)".
This requires increased clearance and creepage distances
(1 inch and 2 inches respectively) at the input side of the device,
which are achieved by mounting terminal blocks. The
3RV29 28-1H terminal block is simply screwed onto the basic
unit.
Link modules
Starters can be easily assembled from single devices with the
help of the link modules. The following table shows the various
possible combinations for devices with screw connection or
spring-type terminals.

Another way to obtain the increased clearance and creepage
distances for Type E is to mount the 3RV29 28-1K phase barriers.
Special three-phase feeder terminals are required for constructing "Type E Starters" with an insulated three-phase busbar system
(see "Busbar Accessories").
Note:
According to CSA, the terminal blocks and the phase barriers
can be omitted when the device is used as a "Self-Protected

Overview
Enclosures 1)
For stand-alone installation of 3RV20 to 3RV24 motor starter
protectors size S00 (In max = 16 A) and S0 (In max = 32 A), cast
aluminum 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).
All enclosures are equipped with N and PE 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 knockout 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 auxiliary switch and with
lateral auxiliary switch. The installation of a motor starter protector with signalling switch is not intended.

Overload Relays
SIRIUS 3RU2 Thermal Overload Relays
General data
■ Overview
The 3RU21 thermal overload relays up to 40 A have been
designed for current-dependent protection of loads with
normal starting (for "Function" see note on Technical Information
on page 5/1) against excessive temperature rises due to
overload or phase failure.

1 Connection for mounting onto contactors:
Optimally adapted in electrical, mechanical and design terms to the
contactors. The overload relay can be connected directly to these
contactor using these pins. Stand-alone installation is possible as
an alternative (in conjunction with a terminal bracket for stand-alone
installation).
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 NC contact is closed
again when the button is released.
6 Supply terminals:
Depending on the device version, the terminals for screw,
spring-type or ring lug terminal connection are configured for the
main and auxiliary circuit.
An overload or phase failure results in an increase of the motor
current beyond the set rated motor 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
switch-off 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 (for "Characteristic Curves" see the note
on Technical Information on page 5/1).
The "tripped" status is signaled by means of a switch position
indicator. Resetting takes place either manually or automatically
after a recovery time has elapsed (for "Function" see note on
Technical Information on page 5/1).
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.
"Increased safety" type of protection EEx e according to
ATEX directive 94/9/EC
The 3RU21 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 areas subject to explosion
hazards – Increased safety "e"); see Chapter 9 "Appendix"
--> "Standards and approvals" --> "Type overview of approved
devices for explosion-protected areas (ATEX Explosion
Protection)".
EC type test certificate for Category (2) G/D has been
submitted. More details on request.
A sealable transparent cover can be optionally mounted
(accessory). It secures the motor current setting against
adjustment.

General data
■ Application
Industries
Ambient conditions
The 3RU21 thermal overload relays are suitable for customers
from all industries who want to guarantee optimum currentdependent protection of their electrical loads (e. g. motors)
under normal starting conditions (CLASS 10).
The 3RU21 thermal overload relays have temperature compensation in accordance with IEC 60947-4-1 for the temperature
range of -40 to +60 °C. For temperatures from +60 to +80 °C the
upper set value of the setting range must be reduced by the
factor listed in the table below.
Application
Ambient
temperature
The 3RU21 thermal overload relays have been designed for the
protection of three-phase and single-phase AC and DC motors.
If single-phase AC or DC loads are to be protected by the 3RU21
thermal overload relays, all three bimetal strips must be heated.
For this purpose, all main current paths of the relay must be
connected in series.

1 Connection for mounting onto contactors:
Optimally adapted in electrical, mechanical and design terms to the
contactors and soft starters. The overload relay can be connected
directly using these connection pins. Stand-alone installation is
possible as an alternative (in conjunction with a terminal bracket for
stand-alone installation).
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 3RB31 an electrical
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 (device 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 3RB31):
Using the rotary switch you can set the required trip class and
activate the internal ground-fault detection dependent on the
start-up conditions.
7 Connecting terminals (removable joint block for auxiliary circuits):
Depending on the device version, the terminals for screw and
spring-type connection are configured for the main and auxiliary circuit.
A sealable transparent cover can be optionally mounted
(accessory). It secures the motor current setting against adjustment.
The 3RB30 and 3RB31 solid-state overload relays up to 40 A
with internal power supply have been designed for inverse-time
delayed protection of loads with normal and heavy starting
(for "Function" see note on Technical Information on page 5/1)
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 rated motor 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 (for
"Characteristic Curves" see the note on Technical Information on
page 5/1).
In addition to inverse-time delayed protection of loads against
excessive temperature rises due to overload, phase unbalance
and phase failure, the 3RB31 solid-state overload relays also allow internal ground-fault detection (not possible in conjunction
with contactor assemblies for wye-delta starting). This provides
protection of loads against high-resistance short-circuits due to
damage to the insulation material, moisture, condensed water
etc.
The "tripped" status is signaled by means of a switch position
indicator. Resetting takes place either manually or automatically
after a recovery time has elapsed (for "Function" see note on
Technical Information on page 5/1).
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.
"Increased safety" type of protection EEx e according to
ATEX directive 94/9/EC
The 3RB30/3RB31 solid-state 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 areas subject to
explosion hazards – Increased safety "e"); see Chapter 9
"Appendix" --> "Standards and approvals" --> "Type overview of
approved devices for explosion-protected areas (ATEX
Explosion Protection)".
3RB31 23-4VE00 solid-state overload relays
■ Benefits
The most important features and benefits of the 3RB30/3RB31
solid-state overload relays are listed in the overview table (see
"General data" on page 5/36).

■ Overview
Overload Relays
SIRIUS 3RB3 Solid-State Overload Relays
General data
■ Application
The 3RU21 thermal overload relay or the 3RB22/3RB23 solidstate overload relay can be used for single-phase AC loads. For
DC loads we recommend the 3RU21 thermal overload relay.
Industries
The 3RB30/3RB31 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.
Ambient conditions
The devices are insensitive to external influences such as
shocks, corrosive environments, ageing and temperature
fluctuation.
For the temperature range from –25 to +60 °C, the 3RB30/3RB31
solid-state overload relays compensate the temperature
according to IEC 60947-4-1.
Application
The 3RB30/3RB31 solid-state overload relays have been
designed for the protection of induction motors in sinusoidal
50/60 Hz voltage networks. The relays are not suitable for the
protection of single-phase AC or DC loads.
■ Accessories
The following optional accessories are available for the
3RB30/3RB31 solid-state overload relays:
• Terminal bracket for stand-alone installation with screw or
spring-type terminals for all sizes
• Mechanical RESET for all sizes
• Cable release for resetting devices which are difficult to
access for all sizes
• Sealable cover for all sizes
