ABSTRACT:
A molded case circuit breaker movable contact arm or carrier electrically connects with the circuit breaker trip unit or load terminal without requiring a flexible electrical conducting braid. The contact carrier is pivotally arranged within a contact carrier support to which the trip unit or load terminal lug is attached. The contact carrier pivot pin is supported on a pair of parallel posts extending from the contact carrier and a spring clip is positioned around the parallel posts and the pivoting end of the contact carrier to promote good electric transport without interfering with the rotational movement of the contact carrier.
