SIRIUS 3RM1 Motor Starter - Compact Motor Control

Why 3RM1 motor starter?

The SIRIUS 3RM1 motor starter switches and protects small motors up to 3 kW. It is available as a direct-on-line and reversing starter, including versions with safety functionality.

Address the challenge of limited space in control panels. This motor starter saves up to 75% of space with its compact 22.5 mm width. It features durable and energy-saving hybrid switching technology to optimize your panel layout.

Combine multiple functions like direct-on-line and reversing starting with overload protection in one device to reduce your component count. The hybrid switching technology uses low-wear semiconductors and energy-saving relay technology to improve durability. Simplify wiring for multiple motor starters using a special infeed system and a three-phase busbar to make installation easier.
