MOLDED CASE CIRCUIT BREAKER OPERATING CRADLE CONFIGURATION

摘要

A molded case circuit breaker of the type containing an elec- tronic trip unit and a combined actuator-accessory unit to ar- ticulate the circuit breaker operating mechanism employs an op- timum cradle configuration within the circuit breaker operating mechanism. The optimized cradle interacts with the circuit breaker latch assembly to substantially reduce the tripping force required to articulate the operating mechanism.
