Mechanical interlock for contactors MC1G 4p AC1 350-400A SE MFR3304 Systeme Electric

Mechanical interlocking for four-pole contactors of the SystemePact MC1G series with a rated current of 350-400 A according to application category AC1. The mechanical interlock is designed to connect two contactors and form a reversing assembly. A reversing contactor is used to switch between power circuits or change the direction of electric motor rotation. In this case, the mechanical interlock prevents the simultaneous switching on of both contactors, preventing a short circuit and increasing operational safety.
