A rear panel for a draw-out circuit breaker includes a metal plate having a pair of rectangular cutouts. Two bushing blocks are joined together and at least partially extend through the cutouts. Each molded bushing block includes three bushings, each of which carry an electrical conductor that is over-molded therein.

Bushing assembly for draw-out circuit breaker

A permanently installed manual trip mechanism is mounted internally to a circuit breaker with a user operated handle extending to the outside of the enclosure. The mechanism converts a relatively small operator input to larger spring charge. Upon triggering, the mechanism provides the required operating velocity of the circuit breaker during the opening stroke for load break operation.
