The crossbar is fabricated from a plastic molding composition having slots 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.
