ABSTRACT:
A circuit breaker design and process for high speed assembly utilizes a unique secondary latch arrangement to reduce frictional forces and increase the breaker calibration test yield. The design allows for interchangability of the trip unit by first pre-assembling the arc chute cavity and operating mechanism. Arrangement of the primary and secondary latch pivots reduces the trip force for further increase in the calibration yield.
