ABSTRACT:
A manually operated trip operator is inserted within a recess formed in a molded case circuit breaker cover, and extends down within the breaker case to interact with the circuit breaker trip bar. The trip operator is formed from a unitary thermoplastic configuration which integrally includes means for interacting with the circuit breaker trip bar and for biasing the trip operator back to its initial position. The unitary manual trip operator is down-loaded into the circuit breaker cover in an automated circuit breaker assembly process.
