Mechanical interlock for contactors MC1G 4p AC1 500-700A SE MFR5004 Systeme Electric

Mechanical interlock for four-pole contactors of the SystemePact MC1G series with a rated current of 500-700 A in application category AC1. Mechanical interlock is intended for connecting two contactors and forming 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 engagement of both contactors, preventing a short circuit and increasing operational safety.
