Overview
Functional density/space savings
The 3RM1 motor starters combine the functions direct/reversing
starting and overload protection and safety-related shutdown in
a single device, without changing the 22.5mm width.
For simple applications (such as starting and reversing threephase loads with overload protection), motor starter combinations of power contactors and a solid-state overload relay, for
example, can be replaced by a single 3RM1 starter. The more
functions are required, the more devices can be replaced. The
footprint area required for each motor starter in the control cabinet is reduced by values of 64 to 82%.
In the case of assemblies and grouped starter units there are
further advantages.
Wiring overhead
3RM12 motor starter with reversing functionality and electronic overload
protection
SIRIUS 3RM1 motor starters are compact devices with a width of
22.5 mm, combining a large number of functions in a single enclosure. They consist of combinations of relay contacts, power
semiconductors (hybrid technology), and a solid-state overload
relay for operational switching of three-phase motors up to 3 HP
(at 480 V).

By combining various functions in a single device, wiring overhead is reduced. The greater the number of starters, the greater
the saving in wiring. Savings can be made in:
• mains wiring and space reduction with the use of the 3RM19
three phase infeed system
• wiring of the reversing contactor assembly thanks to the
integrated design
• reduction of control cables for the coils in group applications
with the 3ZY12 device connectors
8
These savings reduce the time required for the wiring itself, while
at the same time reducing both the risk of wiring errors and the
amount of testing required after control cabinets have been
completed.
Configuration and inventory
The wide setting range of the electronic overload release (up to
1:5) reduces the cost of inventory and the considerations involved in configuration where the actual motor current to be expected is concerned. Compared with protection equipment with

reversing starters and as versions with safety-related shutdown.
Connection methods
Hybrid technology
The 3RM1 motor starters combine the benefits of semiconductor
technology and relay technology. This combination is also
known as hybrid technology. The hybrid technology in the motor
starter is characterized by the following features:
• The inrush current is is conducted briefly via the semiconductors.
Advantage: protection of relay contacts, long service life due
to low wear
• The continuous current is conducted via relay contacts.
Advantage: lower heat losses compared with the semiconductor.
• Shutdown is implemented again via the semiconductor.
Advantage: the contacts are only slightly exposed to arcs, and
this results in a longer service life.
The 3RM1 is available with screw terminal, push-in terminals or
a combination of both..
Push-in terminals are a form of spring-type connection allowing
fast wiring without tools for rigid conductors or conductors
equipped with end sleeves.
Fine-stranded or stranded conductors with no end finishing are
wired using a screwdriver (with a 3.0 x 0.5 mm blade).
As with other spring-type terminals, a screwdriver is also required to release the conductor. The same tool as above can be
used for this purpose.
The advantages of the push-in terminals are found, as with all
spring-type terminals, in speed of assembly and disassembly
and vibration-proof connection. There is no need for the
checking and tightening required with screw terminals.

Safety-related shutdown/safety integration
Feedback to the control system
Thanks to the redundant design of the main circuit and internal
monitoring, safety-related shutdown in accordance with SIL 3 / PLe
is possible by shutting down the control supply voltage with
3RM11 Failsafe and 3RM13 Failsafe motor starters. Additional
safety relays are not required in the main circuit.
The electronic output in the 24 V DC control voltage version of
the 3RM10 and 3RM12 motor starters allows the status of the
connected motor to be reported to the higher-level control
system. If the motor starter is controlled via inputs IN1 to 2, once
the motor has been switched on and has started up correctly the
output "OUT" is set.
3RM1 motor starter
Infeed system for the main circuit
The 3RM19 infeed system available as an accessory for the
main circuit with three-phase busbars allows fast, virtually errorfree wiring of motor starters on the mains connection side and
may reduce the number of short-circuit protective devices.
IC01_00178
3SK1 safety relay
Motor
Combination of four SIRIUS 3RM1 Failsafe motor starters with SIRIUS
3SK1 safety relay to allow safety-related collective disconnection of
connected motors
3RM1 motor starters are ideal for combining with the 3SK1 safety
relay (see Chapter 13 "Safety Technology" "SIRIUS 3SK1 Safety
Relays"). They can be combined by means of:
• conventional wiring
• a special device connector
8
This makes it very simple to shut down connected motors collectively. The wiring, and ultimately the shutting down of the control
supply voltage in Emergency Stop situations, is performed via
the device connector. There is no further need for complex looping of the connecting cables.

Overview of the energy management process
We offer you a unique portfolio for efficient industrial energy
management, using an energy management system that helps
to optimally define your energy needs. We split up our industrial
energy management into three phases – identify, evaluate, and
realize – and we support you with the appropriate hardware and
software solutions in every process phase.
The innovative products of the SIRIUS Industrial Controls portfolio can also make a substantial contribution to a plant's energy
efficiency (see www.siemens.com/sirius/energysaving).
Product advantages
The SIRIUS 3RM1 motor starters offer a number of benefits:
• Greater endurance and reduced heat losses thanks to hybrid
technology
• Less space required in the control cabinet (64 to 82%) as a
result of higher functional density
• Less wiring and testing required as a result of integrating
several functions into a single device
• Lower costs for stock keeping and configuration as a result of
the wide setting range of the electronic overload release
(up to 1:5)
• Fast wiring without tools for rigid conductors or conductors
equipped with end sleeves thanks to push-in spring-type
connections
• Motor status feedback to the higher-level control system in the
case of 3RM10 and 3RM12 motor starters in the 24 V DC version
• Virtually error-free wiring on the mains connection side and
reduction in short-circuit protective devices by means of
3RM19 comb busbar and infeed system
With 3RM1 motor starters, control cabinets warm up less because power losses have been reduced by operation:
• Lower intrinsic power loss (than comparable motor starters
with thermal overload trips) thanks to electronic current
analysis
• Lower control circuit power losses (compared with conventional switching devices) as a result of electronic control of
switching points
• Thanks to the above advantages, additional energy savings
are possible because less cooling is required and a more
compact design is possible

Overview
Accessories for 3RM1 motor starters
The following accessories are available for the 3RM1 motor
starter:
• 3-phase infeed system for the main circuit
• Device connectors for the control circuit
• Spare terminals for main and control circuits
- With screw terminals
- With push-in spring-type terminals
• Push-in lugs for wall mounting the motor starters
• Sealable cover as protection against unauthorized access
Three-phase infeed system
(3RM19 three-phase busbar system)
These busbars are available in three lengths, thus allowing
2, 3 or 5 motor starters (arranged side-by-side) to be connected
at the same time. More than 5 devices can be connected by
clamping the connection tags of an additional busbar rotated by
180° (e.g. 6 devices using one 5-pole busbar and one 2-pole
busbar).
A single motor starter can be removed from the assembly without loosening the terminal screws of neighboring motor starters.
The maximum summation current must not exceed 25 A. Primary
infeed is connected via a three-phase infeed terminal.
The three-phase busbars are finger-safe but empty connection
tags must be fitted with covers.
Special three-phase busbar systems can be used to provide an
easy, time-saving and safe means of feeding two or more 3RM1
motor starters with screw terminals.

Device connectors for the control circuit
The outlay for cabling between the devices is reduced using
device connectors snapped onto a mounting rail, or screwed
onto a level mounting panel (one device connector per motor
starter).
By using device connectors, several motor starters can be jointly
supplied with a control supply voltage of 24 V DC. This requires
the control supply voltage to be applied to the A1 and A2 terminals of only one motor starter.
Up to ten motor starters can be connected with device connectors. The 24 V DC control supply voltage must be within the
operating range of 0.9 to 1.1 for this purpose. If the full operating
range of 0.8 to 1.25 is to be used, no more than five motor starters can be used.
IC01_00218
Using the device connectors only for feeding in the control
supply voltage
If the motor starters are not to be interconnected side-by-side,
device daisy chain connectors must be used for the gaps.
When removing a motor starter, the corresponding device connector must be replaced by a device daisy chain connector if the
control voltage is not to be interrupted for motor starters on the
right.
The last motor starter in a row can be placed on a device termination connector. Flush termination of the configuration is thus
possible.
Device connectors snapped onto a standard mounting rail to allow the
joint connection of the control supply voltage for 3RM1 motor starters or
connection to the 3SK1 safety relays
Using device connectors in conjunction with 3SK1 safety relays
Usage restrictions for accessories
• The 3RM19 3-phase infeed system for the main circuit can
only be used with 3RM1 motor starters with screw terminals.
• The device connectors are only suitable for 3RM1 motor
starters with a control supply voltage of 24 V DC.
Interconnection of several Standard or Failsafe version motor
starters into a group can also be used for joint disconnection by
a 3SK1 safety relay.
To provide for the simultaneous and safe shutdown of several
motor starters via a SIRIUS 3SK1 Safety Relay, you can simply
interconnect the devices without additional wiring using a device
connector.
The motors can then also be shut down safely according to
SIL 3 / PLe with the motor starters.
Up to five motor starters can be operated on one safety relay
with device connectors. If the motor starters are not to be interconnected side-by-side, device loop through connectors must be
used for the gaps.
The last motor starter in a row must be placed on a device termination connector. This closes the circuits that were built up with
the connectors.
