Method of fabricating a molded case circuit breaker |
摘要 |
An interchangeable operating mechanism assembly for molded case circuit breakers having a detachable movable contact arm and trip unit assembly allows the same mechanism assembly to be employed across a wide range of breaker ratings. A snap-on common trip bar attachment further allows multiple-pole facility off the common interrupter mechanism assembly. The mechanism assembly is designed to maintain the operating handle in the "on" position upon the occurrence of a welded contact and prevents the mechanism from being reset.
