Abstract

A molded case circuit breaker and current suppressing unit protects an electric motor without tripping during motor current reversal. Upon the occurrence of a short circuit within the protected circuit, the current suppressing feature rapidly suppresses the let-through current until the circuit breaker responds to isolate the protected equipment. Power is restored to the protected equipment without the need to replace any of the current suppressing unit components.
