MOLDED CASE CIRCUIT BREAKER LOW FRICTION LATCH ASSEMBLY

摘要

MOLDED CASE CIRCUIT BREAKER LOW FRICTION LATCH ASSEMBLY A circuit breaker latch assembly eliminates the need for polishing the opposing latch surfaces to reduce static surface friction and lower the latching force. The end of the circuit breaker cradle operator is offset relative to the restraining surface of the armature-latch to reduce the static friction that must be overcome to move the armature-latch away from the cradle operator. Subsequent release of the cradle operator then allows the circuit breaker operating mechanism to separate the circuit breaker contacts upon the occurrence of predetermined overload current conditions.
