Power contactors for motors

Power contactors for switching motors



Switching of electric drives or motors: a classic product with a decades-old functional principle interpreted in a modern and future-oriented way: these are our contactors, a generalist for switching motors.

 

Whether switching normal motors or high-efficiency motors (IE3), whether reversing or star-delta starting from the smallest to the largest power range, whether classic screwing or connecting using spring-cage technology or direct digital control. Our motor contactors can do all this and much more. No drive is too small or no motor start-up too heavy.
