The contactors can be directly plugged into the manual motor protector PKZ2/ZM-... to form a magnetic motor protector combination. Contactors that are individually mounted can also be mechanically interlocked using the MV-PKZ2 mechanical interlock, e.g. for reversing applications. The DC operated contactor comes standard with 1 N.O. contact and built-in surge suppression. Coil exchange and different auxiliary contact configurations are not possible.
