SIRIUS 3RM1 motor starters are compact devices 22.5 mm wide, combining a large number of functions in a single enclosure. They consist of combinations of relay contacts, power semiconductors (hybrid technology), and an electronic overload relay for switching induction motors up to 3 kW (at 400 V) and resistive loads up to 10 A (at AC voltages to 500 V) under normal operating conditions.
The 3RM1 motor starters with overload protection with wide setting range are offered as direct-on-line starters and reversing starters and as versions with safety-related shutdown up to SIL3 / PL e.
