Abstract
A circuit breaker having a crank for coupling a switching mechanism to the contact pole structure is presented. The crank has a pair of cam surfaces which cooperate with a blocking lever to restrict movement of the operating handle when the contacts of the circuit breaker are welded. The blocking lever is arranged such that it does not interfere with the handle under normal operating conditions.
