Circuit breaker with interlock for welded contacts. |
摘要 |
<p>A circuit breaker includes an interlock which prevents movement of the handle to the off position when the contacts are welded closed. The interlock includes a pair of floating links which jam between slots in arms of the yoke of a spring powered operating mechanism which carries the handle, and recesses in the rotatable cross-bar carrying the movable contact arms. The recesses are offset from the rotational axis of cross-bar so that an attempt to move the switch to the off position generates a moment which will break open lightly welded contacts. <IMAGE></p> |
