SIRIUS 3RA2 Motor Starters
General data
■ Overview
3RA2 motor starters
Tripping times
The 3RA2 fuseless motor starters consist of the 3RV2 motor
starter protector and the 3RT2 electromechanical contactor. The
devices are electrically and mechanically connected using preassembled assembly kits (link modules, wiring kits and standard
mounting rail or busbar adapters).
All 3RA2 motor starters described here are designed for normal
starting, in other words for overload tripping times of less than
10 s (CLASS 10). At rated-load operating temperature the tripping times are shorter, depending on the particular equipment
and the setting range. The exact values can be derived from the
tripping characteristics of the motor starter protectors.
Around 500 preassembled 3RA2 combinations of these innovative 3RT2 controls and 3RV2 protection equipment can be
ordered for direct-on-line and reversing starting of standard induction motors up to 32 A (approx. 20 HP/460 V).
In the 3RA2 motor starter, the 3RV2 motor starter protector is
responsible for overload and short-circuit protection. Back-up
protective devices, such as melting fuses or limiters, are superfluous here, as the motor starter protector is capable of withstanding short-circuits up to 65 kA at 480 V and 30 kA at 600 V.
See the the actual SCCR ratings by device listed on the selection
pages of this chapter.
For all 3RA2 starters up to 32 A, spring-type connection is available as well as screw connection. To connect two devices with
spring-type connection there are plug-in connection modules for
sizes S00 and S0 which enable very quick mounting of the starters and a vibration-resistant assembly.
To connect a motor starter protector with screw connection to a
contactor with spring-type connection there are special hybrid
connection modules for S00 and S0.
The 3RT2 contactor is particularly suitable for extremely
complex switching tasks requiring the greatest endurance.
Screw terminals

Operating conditions
3RA2 motor starters are climate-proof. They are intended for use
in enclosed rooms in which no severe operating conditions
(such as dust, caustic vapors, hazardous gases) prevail. Suitable covers must be provided for installation in dusty and damp
locations.

These terminals are indicated in the corresponding
tables by the symbols shown on orange
backgrounds.
While starters can be assembled with either spring-type or
screw connection, the pre-assembled versions offered in this
chapter are with screw terminals only. For spring-type versions,
simply order the components listed on the spring-type terminal
pages and assemble these starters quickly and efficiently without the use of any tools.

SIRIUS 3RA2 Motor Starters
General data
The 3RA2 fuseless motor starters can be ordered as preassembled complete units for direct-on-line starting (3RA21) or for
reversing duty (3RA22) with screw connection.
The fuseless motor starters can also be assembled easily by the
customer. It is simply necessary to assemble the standard 3RV2
motor starter protector, the 3RT2 contactor and the appropriate
assembly kit.
Control supply voltages of AC 50/60 Hz 110/120 V and 24 V DC
are available to choose from.
For single devices and assembly kits see "Selection and ordering data" for 3RA21 direct-on-line starters and 3RA22 reversing
starters.
A distinction is also drawn between whether the starter is
mounted on a 35 mm standard mounting rail, on a flat surface
using screws, or on a 60 mm busbar system.
For assembly kits for direct-on-line starting or reversing duty for
mounting on standard mounting rails or busbars see "Selection
and ordering data" for "Accessories".
Accessories
For reversing starters size S0 it is imperative to use a standard
mounting rail adapter in order to ensure the necessary mechanical strength. A standard mounting rail adapter is not necessary
if a busbar adapter is used.
As the 3RA2 fuseless motor starters are constructed from 3RV2
motor starter protectors and 3RT2 contactors, the same accessories - such as auxiliary switches, undervoltage releases or
door-coupling rotary operating mechanisms - can be used for
the 3RA2 fuseless motor starters as for these motor starter protectors and contactors.
In particular, certain accessories have been optimized for the
fuseless motor starters. They include the top-connected, transverse auxiliary switch on the motor starter protector, which is
available with 1 CO contact or 1 NO contact + 1 NC contact.
Special auxiliary switch blocks that can be snapped on from
below are available for the contactor. These two accessories
enable the fuseless motor starters to be wired simply without
having to route cables through the device.
Incoming energy supply
On the whole four different infeed possibilities are available (see
"3RV29 Infeed System for Motor Starters" on page 6/31).
Customer assembly of fuseless motor starters
While the preassembled 3RA2 can be ordered up to 32 A, combinations in customer assembly without link modules are also
possible up to 40 A (approx. 25 HP/460 V).
Thanks to the SIRIUS modular system, the standard devices can
be optimally combined in terms of both technical specifications
and dimensions.
The 3RA1 fuseless motor starters can be used for the fuseless
motor starters between 32 A and 100 A.
The SENTRON 3VL circuit breakers and the SIRIUS 3RT contactors are available for rated currents >100 A.
Special equipment for customer assembly can be ordered if
other rated control supply voltages are required. Assembly kits
can be used to facilitate assembly.
Customers can also assemble tested combinations of motor
starter protectors with solid-state controls (soft starters, solidstate contactors) and motor starters with additional monitoring
and control devices (3RR monitoring relays, SIMOCODE 3UF).
For the electrical and mechanical connection of protection
equipment and controls there are preassambled assembly kits
(link modules, wiring kits and standard mounting rail or busbar
adapters).
The following types of configuration are possible:
• Direct-on-line/reversing starting (see preassembled 3RA2
combinations)
• Wye-delta starting (only customer assembly with link module)
• Solid-state/soft starting (only customer assembly with link
module)

SIRIUS 3RA2 Motor Starters
General data
Communications integration using IO-Link
Motor starters can also be assembled with IO-Link for connection to the higher-level control system. For each starter this
requires a communication-capable contactor onto which a
3RA27 11 function module is plugged (various versions for
direct-on-line, reversing and wye-delta starts). The design of the
SIRIUS motor starters permits a group of up to 4 SIRIUS controls
to be conveniently connected through a standardized IO-Link to
a control system, reducing wiring time considerably compared
to the conventional parallel wiring method. The electrical connection is made using only a single cable with three conductors.
The function modules perform not only the communication (contactor operation and feedback, ready signal) but also the electrical interlocking (for reversing and wye-delta starters) and the
timing relay function (wye-delta reversing time).
Communication information and control supply voltages are
passed on through ribbon cables so that the complete control
current wiring on the starter is no longer needed.
6
The monitoring and maintenance of a plant is made considerably easier by transmitting diverse diagnostics data from the
function modules (e. g. missing main and auxiliary voltage, local
disconnection…) through IO-Link to the higher-level control system. Also, starters equipped for IO-Link can be conveniently
controlled from the control cabinet door using the optional operator panel.
This results in a significant reduction of wiring compared to the
conventional parallel wiring method. The electrical connection is
made using standard cables.
The function modules perform not only the communication (contactor operation and feedback, ready signal) but also the electrical interlocking (for reversing and wye-delta starters) and the
timing relay function (wye-delta reversing time).
Communication information and control supply voltages are
passed on through ribbon cables so that the complete control
current wiring on the starter is no longer needed.
More information:
• For AS-Interface see Chapter 2 "Industrial Communication"
• For 3RA27 function modules see Chapter 3 "Controls –
Contactors and Contactor Assemblies" --> "Function
Modules".
Contactors with communication interface
For assembling motor starters with communications integration
(AS-i/IO-Link) you need contactors with a communications interface. These contactors are not included as standard in the
preassembled 3RA2 motor starters. A motor starter with communications interface must be assembled by the customer from
individual devices.
Complete integration in the automation landscape
More information:
• For IO-Link see Chapter 2 "Industrial Communication"
• For 3RA27 function modules see Chapter 3 "Controls –
Contactors and Contactor Assemblies" --> "Function
Modules".
As the result of the communication connection through IO-Link
or AS-i, the SIRIUS motor starters are fully integrated in the automation landscape and can draw on all the advantages of TIA
(e. g. integration in the TIA Maintenance Station).
Communications integration through AS-Interface
3RA2 fuseless motor starters are available:
• For mounting onto standard mounting rails TH 35 according
to EN 60715 (depth 15 mm)
• For mounting onto busbar adapters (busbar center-to-center
clearance 60 mm, bar thickness 5 to 10 mm)
Connection of the motor starters to the higher-level control system is possible not only through IO-Link but also through
AS-Interface. The AS-Interface connection is recommended
wherever motor starters are used in distributed applications.
This solution also requires a communication-capable contactor
and a corresponding 3RA27 12 function module (various versions for direct-on-line, reversing and wye-delta starts). The
devices are implemented in A/B technology, making it easy to
connect up to 62 starters to an AS-i master (regardless of
whether they are direct-on-line, reversing or wye-delta starters).
Mounting
The fuseless motor starters are also suitable for screw fixing using two 3RV29 28-0B push-in lugs.
The 3RA2 fuseless motor starters can also be configured with
the 3RV29 infeed system (see Chapter 5 "Protection Equipment"
--> "SIRIUS 3RV2 Motor Starter Protectors up to 40 A"
■ Benefits
The 3RA2 fuseless motor starters offer a number of advantages:
• Minimum planning and assembly work and far less wiring with
the preassembled complete units (only one order number
3RA2)
• Plug-in connectors from the motor starter protector to all types
of SIRIUS controls, for quicker and error-free assembly of
starters with screw and spring-type connection
• High planning reliability through consistent combination tests
for fuseless (400 V according to IEC) and fused configuration
(400 V, 500 V and 690 V according to IEC)
• Comprehensive approvals for use world-wide
(please ask for details of availability)
6/4
SIRIUS Innovations Supplement 2011
• Uniform accessories for the two sizes S00 and S0
• Spring-type connection possible throughout: Enhanced
operational reliability (vibration-resistant wiring) and less
wiring work thanks to plug-in connections
• Power loss 5 to 10 % smaller than for legacy 3RA1 devices,
hence lower power consumption
• Connection of starters to the control system through standardized system connection (IO-Link and AS-i), for fast integration
in TIA and less wiring work. Requires communication contactor versions which are not offered in pre-assembled 3RA2
starters.

SIRIUS 3RA2 Motor Starters
3RV29 infeed system for motor starters
■ Overview
Types of infeed for 3RA2 motor starters
8US busbar adapters for 60 mm systems
On the whole, four different power infeed possibilities are
available:
• Parallel wiring
• Use of insulated three-phase busbars (combination with
SIRIUS motor starter protectors and contactors possible)
• 8US busbar adapters for 60 mm systems
• SIRIUS 3RV29 infeed systems
The motor starters are mounted directly with the aid of busbar
adapters on busbar systems with 60 mm center-to-center clearance in order to save space and to reduce infeed times and
costs.
Insulated three-phase busbar systems
Three-phase busbar systems provide an easy, time-saving and
clearly arranged means of feeding 3RA2 motor starters with
screw terminals. Different versions are available for sizes S00
and S0 and can also be used for the various different types of
motor starter protectors.
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.
The starters are snapped onto the adapter and connected on
the line side. This prepared unit is then plugged directly onto the
busbar system, and is connected both mechanically and electrically at the same time.
For "Selection and ordering data" see page 6/27.
The busbars are suitable for between 2 and 5 starters. 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.
A combination of starters of different sizes is possible with sizes
S00 and S0. Connecting pieces are available for this purpose.
The motor starter protectors are supplied by appropriate starter
terminals.

Three-phase insulated 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" of size S0 or S2 according to UL/CSA. Special
type E terminals must be used for this purpose however.
SIRIUS 3RV29 infeed systems
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 spring-type connection up to size S0.
The system is based on a basic module complete with a lateral
incoming unit (three-phase busbar with infeed) which has two
slots.
Expansion modules are available for extending the system
(three-phase busbars for system expansion).
For 3RV29 infeed system see Chapter 5 "Protection Equipment"
--> "SIRIUS 3RV2 Motor Starter Protectors up to 40 A"
--> "Accessories" --> "3RV29 Infeed System".
For selection and ordering data see Chapter 5 "Protection

SIRIUS 3RA6 Compact Starters
General data
■ Overview
3RA6 compact starters and infeed system for 3RA6
Communications integration using IO-Link
Up to 4 IO-Link compact starters (reversing and direct-on-line
starters) can be connected together and conveniently linked to
the IO-Link master through a standardized IO-Link connection.
The SIRIUS 4SI solid-state module is used for example as an
IO-Link master for connection to the SIMATIC ET 200S distributed I/O system.
The IO-Link connection enables a high density of information to
be passed from device to PLC.
For details on the communications integration using IO-Link see
Chapter 2 "Industrial Communication" --> "IO-Link".
The diagnostics data of the process collected by the 3RA6 compact starter, e. g. short-circuit, end of service life, limit position
etc., are not only indicated on the compact starter itself, but also
transmitted to the higher-level control system through IO-Link.
An optional operator panel, which can be installed in the control
cabinet door, allows for easy control of the 3RA6 IO-Link compact starter from the control cabinet door.
Permanent wiring / easy replacement
3RA62 reversing starter
Integrated functionality
The SIRIUS 3RA6 compact starters are a generation of innovative motor starters with the integrated functionality of a motor
starter protector, contactor and solid-state overload relay. In
addition, various functions of optional mountable accessories
(e. g. auxiliary switches, surge suppressors) come standard
with the SIRIUS compact starter.
Application
6
The SIRIUS compact starters can be used wherever standard
induction motors up to 32 A (approx. 20 HP/460 V) are directly
started.
The compact starters are not suitable for the protection of singlephase AC or DC loads.
The Compact Starter carries IEC, UL, and CSA approvals.
Low equipment variance
Thanks to wide setting ranges for the rated current and wide
voltage ranges, the equipment variance is greatly reduced
compared to conventional motor starters.
Using the SIRIUS infeed system for 3RA6 (see page 6/52) it is
possible to carry out the wiring in advance without a compact
starter needing to be connected.
A compact starter can be very easily replaced simply by pulling
it out of the infeed system without disconnecting the wiring.
Regardless of whether the infeed system is mounted to a flat surface, or on a DIN rail, there is no need to disconnect any wiring
(on account of the removable main and control circuit terminals)
in order to replace a compact starter.
Consistent solution from the infeed to the motor starter
The SIRIUS infeed system for 3RA6 (with integrated PE bar) is
offered as a user-friendly possibility of supplying up to 100 A to
attached starters with a maximum wire cross section of 2/0 AWG
while connecting the motor cable directly without additional
intermediate terminals.
Screw and spring-type connections
The SIRIUS compact starters and the infeed system for 3RA6 are
available with screw and spring-type connections.
Screw terminals
Very high operational reliability
Thanks to the high short-circuit breaking capacity and weld-free
capability when the end of service life is reached, the SIRIUS
compact starter achieves a very high level of operational reliability that would otherwise have only been possible with considerable additional overhead. This sets it apart from devices with
similar functionality.
Safe disconnection
The auxiliary switches of the 3RA6 compact starters are designed as mirror contacts. It is thus possible to use the devices
for safe disconnection, e. g. emergency-stops, up to Category 2
(EN 954-1) and together with other redundancy switching devices up to Category 3 or 4.
Communications integration with AS-Interface
To enable communications integration through AS-Interface
there is an AS-i add-on module available in several versions
which can be mounted on the SIRIUS compact starter in place
of its control circuit terminals.
The design of the AS-i add-on module permits a group of up to
62 starters to be connected to the control system using just 4
cables. This reduces wiring work considerably compared to the
conventional wiring method.

Spring-type terminals
These terminals are indicated in the corresponding
tables by the symbols shown on orange backgrounds.
System configurator for engineering
A free system configurator is available to further reduce the
amount of engineering work for selecting the required compact
starters and matching infeed.
Types of infeed for the 3RA6 compact starters
In total, four different infeed possibilities are available:
• Conventional wiring
• Use of three-phase busbars (combination with SIRIUS motor
starter protectors and SIRIUS contactors possible)
• 8US Fast Bus busbar adapters
• SIRIUS infeed system for 3RA6 (see page 6/52)

The overload tripping time can be set on the device to less than
10 s (CLASS 10) and less than 20 s (CLASS 20 for heavy starting). As the breaker mechanism still remains closed after an
overload, resetting is possible by either local manual reset or autoreset after 3 minutes cooling time.
With autoreset there is no need to open the control cabinet.
The SIRIUS 3RA6 compact starters are universal motor starters
according to IEC/EN 60947-6-2. As control and protective
switching devices (CPS) they can connect, convey and disconnect the thermal, dynamic and electrical loads from short-circuit
currents up to Iq = 30 kA, i.e. they are essentially weld-free. They
combine the functions of a motor starter protectors, a contactor
and a solid-state overload relay in a single enclosure and can be
used wherever standard induction motors up to 32 A (up to approx. 20 HP at 480 V AC) are started directly. Available versions
are the direct-on-line starters with 45 mm width and the reversing starters with 90 mm width.

The SENTRON 3VL circuit breakers and the SIRIUS 3RT
contactors can be used for motor starters >100 A.
Diagnostics options
The compact starter provides the following diagnostics options
on site:
• With LEDs
- Connection to the control voltage
- Position of the main contacts
• With mechanical indication
- Tripping due to overload
- Tripping due to short-circuit
- Tripping due to malfunction (end of service life reached
because of worn switching contacts or a worn switching
mechanism or faults in the control electronics)
These states can also be evaluated in the higher-level control
system:
• With conventional wiring using the integrated auxiliary and
signaling switches of the compact starter
• With AS-Interface or IO-Link in even greater detail using the
respective communication interface
Four complement variants for 3RA6 compact starters
• For standard mounting rail or screw mounting:
basic version including 1 pair of main circuit terminals and
1 pair of control circuit terminals
• For standard mounting rail or screw mounting when using the
AS-i add-on module:
comes without control circuit terminals because the AS-i addon module is attached in lieu of them
• For use with the infeed system for 3RA6:
without main circuit terminals because they are supplied with
the infeed system and the expansion modules
• For use with the infeed system for 3RA6 and AS-i add-on
module:
without main or control circuit terminals as they are not needed
• The control circuit terminals are always required by the compact starters for IO-Link; the main circuit terminals depend on
the use of the infeed system.
Additional components of the 3RA6
The two control circuit terminals on the 3RA61/3RA62 allow
access to signalling contacts for overload (1 CO) and shortcircuit / malfunction (1 NO). Furthermore, the 3RA61 has two
auxiliary contacts (1 NO + 1 NC) for indicating the position of the
main contacts, while the 3RA62 has one auxiliary contact (1 NO)
per direction of rotation per main contact.
Operating conditions
The SIRIUS 3RA6 compact starters are suitable for use in nearly
all climates. They are intended for use in enclosed rooms in
which no severe operating conditions (such as dust, caustic vapors, hazardous gases) prevail. Suitable covers must be provided for installation in dusty and damp locations.
The SIRIUS compact starters are generally designed to degree
of protection IP20. The permissible ambient temperature during
operation is -20 to +60 °C.
The maximum short-circuit current based on UL testing is 30 kA
up to 12 A and 15 kA for the 8 ... 32 A versions at 480 V.

To maintain maximum interference immunity in a harsh electromagnetic
environment, additional overvoltage protection should be provided in the
control supply current circuit. A suitable choice is for example the Dehn
Blitzductor BVT AD 24 V, Art. No. 918 402 or an equivalent protective
element.

SIRIUS 3RA6 Compact Starters
Accessories
■ Overview
Accessories for SIRIUS 3RA6 compact starters
8US Fast Bus busbar adapters for 60 mm systems
The following accessories are available for the 3RA6 compact
starters:
• AS-i add-on module: see AS-Interface Add-On Modules for
3RA6, page 6/50
• External auxiliary switch blocks: Snap-on auxiliary switch as
versions 2 NO, 2 NC and 1 NO +1 NC with screw or springtype connections; the contacts of the auxiliary switch block
open and close jointly with the main contacts of the compact
starter. The NC contacts are designed as mirror contacts.
• Control kit: aid for manually closing the main contacts in order
to evaluate the wiring and motor direction under conditions of
short-circuit protection
• Adapter for screw mounting the compact starter, including
push-in lugs
• Main circuit terminals: Available in screw and spring-type terminals
• Main circuit terminals for mixed connection method:
With the main circuit terminal for the mixed connection method
it is also possible in the main circuit to change over from the
screw connection method on the incoming side to the springtype connection method on the outgoing side.
This enables for example the side-by-side mounting of several
compact starters and their cost-effective connection using the
three-phase busbars on the infeed side. The motors are then
directly connected by the quick and reliably contacting
spring-type connection method.
The compact starters are mounted directly with the aid of busbar
adapters on the Fast Bus busbar systems with 60 mm center-tocenter clearance in order to save space and to reduce infeed
times and costs. These starters are suitable for copper busbars
with a width from 12 to 30 mm. The busbars can be 5 mm or
10 mm thick.
Accessories for UL applications
The terminal block for "Self-Protected Combination Motor
Controller", type E is available for complying with the clearance
and creepage distances according to UL 508.

Accessories for infeed using three-phase busbar systems
The three-phase busbars can be used as an easy, time-saving
and clearly arranged means of feeding SIRIUS 3RA6 compact
starters with screw connection. Motor starter protectors size S00
and S0 can also be integrated.
The busbars are suitable for between 2 and 5 devices. However,
any kind of extension up to a maximum summation current of
63 A is possible by clamping the terminals of an additional busbar (rotated by 180°) underneath the terminals of the respective
last motor circuit protector.
A connecting piece is required for the combination with motor
starter protector size S00. S00 and S0 motor starter protectors of
the 3RV2 series do not require the additional connecting piece.
The motor starter protectors are supplied by appropriate feeder
terminals. Special feeder terminals are required for constructing
"Type E Starters" according to UL/CSA.
The three-phase busbar systems are finger-safe but empty
connection terminals must be fitted with covers. They are designed for any short-circuit stress which can occur at the output
side of connected SIRIUS 3RA6 compact starters or motor
starter protectors.
6/44
SIRIUS Innovations Supplement 2011
The 8US Fast Bus busbar system can be loaded with a maximum summation current of 630 A.
The "reversing starter" version requires a device holder along
side the busbar adapter for lateral mounting.
The compact starters 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.
For more accessories such as incoming and outgoing terminals,
flat copper profiles etc., see the Controls 2010 Catalog,
Section 5 "8US Busbar Systems".
Accessories for operation with closed control cabinet doors
Door-coupling rotary operating mechanisms for standard and
emergency-stop applications are available for operating the
compact starter with closed control cabinet doors.
Accessories for SIRIUS 3RA6 compact starters in IO-Link
version
The following accessories are available specifically for the
3RA64, 3RA65 compact starters:
• The 4SI SIRIUS solid-state module as IO-Link master allows
for the simple and economical connection of SIRIUS controls
with IO-Link (e.g up to four groups of 4 compact starters) to
the multifunctional SIMATIC ET 200S distributed I/O system.
• Additional connection cables for side-by-side mounting of up
to 4 compact starters
• Operator panel for local control and diagnostics of up to
4 compact starters coupled to each other

SIRIUS 3RA6 Compact Starters
Infeed systems for 3RA6
■ Overview
The infeed system for 3RA6 compact starters enables far less
wiring in the main circuit and, thanks to the easy exchangeability
of the compact starters, reduces the usual downtimes for
maintenance work during the plant's operating phase.
The infeed system provides the possibility of completely
prewiring the main circuit without a compact starter needing to
be connected at the same time. As the result of the removable
terminals in the main circuit, compact starters can be integrated
in an infeed system in an easy manner (without the use of tools).
In addition, the integrated PE bar means it is optionally possible
to connect the motor cable directly to the infeed system without
additional intermediate terminals. The infeed system for 3RA6
compact starters is designed for summation currents up to
100 A with a conductor cross-section of max. 2/0 AWG on the
feeder terminal block.
The infeed system can be mounted on a standard mounting rail
or flat surfaces.

$ Infeed
. 45 mm adapters for SIRIUS 3RV1 motor starter protectors
The 3-phase infeed is available as an infeed with screw connection (4-2 AWG up to 63 A or 0-2/0 AWG up to 100 A) and a an
infeed with spring-type connection (4-2 AWG up to 63 A).
SIRIUS 3RV1 motor starter protectors size S0 with screw connection can be fitted to the adapter, enabling them to be plugged
into the infeed system.
The infeed with spring-type terminal can be attached to the left
side, as well as the right side, of an expansion module.
Terminal blocks
The screw terminal infeeds are permanently fitted to the left side
of a 3-socket expansion module.
Using the terminal block, three phase power can be fed out of
the infeed system; this means that single-phase, two-phase and
three-phase components can also be integrated in the system.
The infeeds with screw connection enable connection of the
main conductors (L1, L2, L3) either from above or from below.
If the end cover is removed, the terminal block can be inserted
into an expansion module.
The infeeds with screw connection come packaged with 1 end
cover, while the infeed with spring-type connection comes packaged with 2 end covers.
Expansion plug for SIRIUS 3RV19 infeed systems
The expansion module with 3 sockets for compact starters is
available with screw connection and with spring-type
connection.
Expansion modules enable the infeed system to be expanded
and can be connected to each other in any number up to a maximum length of 1.2 meters.
Two expansion modules are held together with the help of
2 connecting plates and 1 expansion plug. These assembly
parts are included in the scope of supply of the respective
expansion module.
When the infeed system for 3RA6 compact starters is used, the
compact starters (plug-in modules) are easily mounted and removed even when live.
Optional possibilities:
• PE connection on motor starter side
• Outfeed for external auxiliary devices
• Connection to 3RV19 or 3RV29 infeed system
• Integration of SIRIUS 3RV1 motor starter protectors size S0
(using 3RA68 90-0BA adapter)
& Two-socket expansion modules
If only 2 instead of 3 additional sockets are required, then the
2-socket expansion module is the right choice. It has the same
functionality as the 3-socket expansion module.
( Expansion plug
Two expansion modules can be connected together using the
expansion plug. Flexible expansion of the infeed system is thus
possible.
) PE infeeds
This module enables a PE cable to be connected.
Maximum rated operational current
The following maximum rated operational currents apply for the
components of the infeed system for 3RA6:
Component

Infeed with screw connection 4-2 AWG
63
Infeed with spring-type connection 4-2 AWG

When several expansion modules are mounted side by side, the
maximum rated operational current from the 2nd expansion
module to the end of the row is 63 A.

To prevent the possibility of short-circuits, the cables on the terminal block
must be installed so that they are short-circuit proof according to
EN 60439-1 Section 7.5.5.1.2.
On the last expansion module of a row, the slot provided for the
expansion plug can be covered by inserting the end cover.

% Three-socket expansion modules
If the end cover is removed, the expansion plug for the SIRIUS
3RV19 infeed system can be inserted into an expansion module.
It connects the infeed system for 3RA6 compact starters with the
SIRIUS 3RV19 infeed system.
