CVS400F VIGI MB TM400D 4P3D

The Schneider Electric CVS400F is a 400A frame molded case circuit breaker equipped with a Vigi MB earth leakage protection module and TM400D thermal-magnetic trip unit, configured as 4P3D (4 poles with 3 protected phases and a switched neutral). This integrated solution provides comprehensive protection against overloads, short circuits, and earth leakage faults in three-phase distribution systems.
