Coupling Relays

Coupling Relays 3RT20

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 over voltages of the coil using an integrated sure suppressor.
