Coupling Relays

Siemens - Koppelschütz

The SIRIUS coupling relays to switch motors and auxiliary and control circuits have been especially designed to operate with electronic control systems.

The contactors distinguish themselves as a result of their low power drain and the wide operating range of the solenoids.The high contact reliability of the auxiliary contacts guarantees that there are no fault signals – even at low switching powers.

Sensitive output stages are protected against switching overvoltages of the coil using an interated sure suppressor.
