3.2 Applications
The 3RM1 motor starters can be used wherever combinations of contactors and overload
relays were previously used.
Thanks to the additional functionality of safety-related shutdown, the 3RM11 Failsafe and
3RM13 Failsafe motor starter variants are ideally suited to safety-related applications up to
SILCL 3 in accordance with EN 62061 and PL e/Cat. 4 in accordance with EN ISO 13849-1.
Short-circuit protection in a load feeder designed in this way must be implemented by
appropriate upstream short-circuit protection devices. These can be, for example, circuit
breakers or appropriate fuses.
You achieve maximum space-savings benefits by means of a group configuration of the
3RM1 motor starters. This enables several 3RM1 motor starters to be protected by one
short-circuit protection device.
The 3RM1 motor starters are used in the following areas, for example:
● Conveyor technology
● Logistics systems
● Production machines
● Machine tools
● Small elevators
