ABSTRACT:
A molded case circuit breaker and current suppressing unit protects an electric motor without tripping during motor current reversal. The circuit breaker trip unit provides long time, short time and instantaneous over current protection against abnormal overload and low-current short circuit currents within the protected circuit. The current suppressing unit rapidly suppresses high-current short circuit currents until the circuit breaker responds to isolate the protected equipment.
