31 ABSTRACT OF THE DISCLOSURE A molded case circuit breaker includes an elongated intermediate latch lever disposed between and in engagement with an intermediate latch plate and a trip bar. The intermediate latch lever is pivotable about a pivot axis and includes a first elongated portion between the latch plate and the pi- vot axis of a length substantially less than the length of a second elongated portion between the pivot axis and the trip bar. The intermediate latch lever so configured reduces the force required and the amount of travel of the trip bar required to ef- fect a trip operation.
