ABSTRACT:
A bimetal in a circuit breaker can deflect in a first direction or a second direction depending upon conditions. If the bimetal deflects in the second direction it can increase the force necessary to operate a trip mechanism of the circuit breaker. A yoke stop helps to control bimetal deflection forces and thus, the amount of force necessary to operate the trip mechanism. This allows better control, size, and selection of operating parts for the circuit breaker.
