Abstract
A molded case circuit breaker includes a highly integrated operating mechanism having an over-center toggle mechanism for opening and closing a pair of separable electrical contacts. A pivotable, one-piece cradle coupled to the breaker handle includes a cradle latch surface for latching with a trip arm of a trip mechanism, a contact stop surface for limiting the movement of one of said electrical contacts and an arcuate cam surface for engaging a cradle cam pin during a reset operation. The arcuate cam surface of the cradle is contoured to enable the resetting of the operating mechanism after a trip operation by applying a relatively low, substantially constant reset force to the breaker handle.
