摘要:
Compound hook apparatus for intercepting and holding circuit breaker contacts in a hooked open position against the closing force of charged operating mechanism springs includes a primary hook releasably latching an intermediate hook in a hooking position to fixedly dispose a pin in intercepting relation with a hook cam carried by a breaker movable contact assembly. The primary hook is articulated to unlatch the intermediate hook, freeing the latter to thereby release the movable contacts from their hooked open position.
