Abstract

A molded case circuit breaker crossbar assembly allows the movable contact carrier, contact spring and contact carrier operating cam to be preassembled prior to insertion within the circuit breaker case. The crossbar is fabricated from a plastic molding composition having means thereon for supporting the movable contact carrier and for retaining the charged contact operating spring. The contact carrier operating cam engages a roller carried by the operating mechanism link to couple the crossbar assembly to the circuit breaker operating mechanism.
