ABSTRACT:
A compact molded case circuit breaker operating mechanism crossbar assembly allows a unitary crossbar design to be used within a wide range of circuit breaker ampere ratings. A common phenolic crossbar and a metal staple are used for the higher ratings. An L-shaped filler in combination with the crossbar and staple are used to adapt the crossbar to the staple for the lower ratings.
