Overview
3RM13 motor starter with reversing functionality, electronic overload
protection and safety-related shutdown
SIRIUS 3RM1 motor starters are compact devices, 22.5 mm
wide, combining a large number of functions in a single enclo-
sure. They consist of combinations of relay contacts, power
semiconductors (hybrid technology), and an electronic overload
relay for operational switching of three-phase motors up to 3 kW
(at 400 V) and resistive loads up to 10 A at AC voltages up to
500 V.
The 3RM1 motor starters with overload protection with wide
setting range are available as direct-on-line starters and revers-
ing starters and as versions with safety-related shutdown up to
SIL 3/PL e.
1)
Operation of resistive loads with maximum 10 A.
2)
Standard three-phase motor, basis 4-pole at 400 V AC; the actual startup
characteristics of the motor as well as its rated data are important factors
here.
The Article No. scheme shows an overview of product versions

Benefits
Product advantages
•
Less space required in the control cabinet (20 to 80 %) thanks
to high functional density, which also means reduced wiring
and testing
•
Greater endurance and reduced heat losses thanks to hybrid
technology;
see www.siemens.com/sirius/energysaving
•
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 spring-type terminals
(push-in)
•
Safety-related shutdown in accordance with SIL 3/PL e by
shutting down the control supply voltage without additional
devices in the main circuit
•
The motor starters can be ideally combined with 3SK safety
relays for safety-related shutdown
(see page 11/10)
•
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 infeed system
•
ATEX certification of the overload protection of the
3RM1 Failsafe motor starters: "Increased safety" type of
protection EEx e according to ATEX directive 94/9/EC
•
The 3RM1 motor starters can be used with highly energy-
efficient IE3/IE4 motors. In this regard, please observe the
information on dimensioning and configuring;
see
"Application Manual for SIRIUS Controls with IE3/IE4 Motors",
.
For more information on IE3/IE4,
see the Preface, page 7
