Abstract: An interlock structure is coupled between actuating structure and a travel adjuster of a circuit breaker. The interlock structure includes a body having a bore therein. An engaging member has a portion sized to be received by the bore and the engaging member is coupled with the travel adjuster for movement therewith. A slide member is movable with respect to the body between operative and inoperative positions. Linkage structure is coupled to the slide member for moving the slide member and is also coupled to the actuating structure such that upon movement of the actuating structure, the linkage structure moves the slide member to the operative position so that the slide member blocks at least a portion of the bore to prevent the engaging member from entering the bore and thus prevents the travel adjuster from moving in a certain direction to allow the closure of the circuit breaker contacts.
