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 Safety Systems -> Safety Relays -> SIRIUS 3SK Safety Relays)
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 2014/34/EU
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 "Configuration Manual for SIRIUS Controls with IE3 Motors", https://support.industry.siemens.com/cs/ww/en/view/94770820
