Abstract

A circuit breaker having a positive-off stop feature includes an operating lever rotatably coupled to a side frame, a tension lever coupled to the side frame, and an upper toggle linkage and a stop link each rotatably coupled to the tension lever. The upper toggle linkage may be configured to rotate the stop link. The operating lever may be configured to move rotatably to and from an ON position and an OFF position provided the main contacts of the circuit breaker are not welded or otherwise stuck together. Should the main contacts become welded or otherwise stuck together, the upper toggle linkage may be configured to rotate the stop link to a position wherein the stop link may be configured to prevent the operating lever from moving into the OFF position. Methods of assembling a circuit breaker positive-off stop feature are also provided, as are other aspects.
