ABSTRACT:
A circuit breaker includes a crank for coupling a rotary arm breaker mechanism to the cradle. The crank has a protrusion which cooperates with a handle yoke to restrict movement of the operating handle when the contacts of the circuit breaker are welded. The crank protrusion is arranged such that it does not interfere with the handle under normal operating conditions.
