3RM13 motor starter with reversing functionality, electronic overload protection and safety-related shutdown

SIRIUS 3RM1 motor starters are compact devices 22.5В 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 3В kW (at 400В V) and resistive loads up to 10В A (at AC voltages to 500В V) under normal operating conditions.

The 3RM1 motor starters with overload protection with wide settingВ range are offered as direct-on-line starters and reversing starters and as versions with safety-related shutdown up to SILВ 3/PLВ e.

Seamlessly integrated safety right through to the main circuit

Problem-free integration of functional safety into the main circuit through the simple combination of 3RM1 and 3SK devices

Functional safety in the main circuit needs to be both simple and flexible.

The unique compatibility of hybrid 3RM1 fail-safe motor starters and 3SK safety relays means that integrated functional safety right through to the main circuit is no longer a problem.

Their compact design allows the motor starters to be installed to the right of the safety relay in a simple manner, just like an output expansion. The wiring of the safety-related signals to the relay can be performed simply, quickly and in an error-free manner using the device connector.

The ergonomically designed enclosure with removable terminals and terminal labeling in the hinged cover allows for the cables to be conveniently diagonally mounted from the front. Either screw-type or spring-loaded terminals with push-in technology are available.

Highlights

• Fail-safe disconnection of motors up to 3В kW
• Problem-free combination of fail-safe motor starters and safety relays
• End-to-end system, simple setup using device connectors
• Ergonomic enclosure
