Abstract

1300203 Automatic circuit breaker WESTINGHOUSE ELECTRIC CORP 19 April 1971 [16 Feb 1970] 23213/71 Heading H1N A circuit interrupter has housing parts 9, 11 which are held together by screws 95 and have aligned holes 99, 97 to receive bolts (not shown) for securing the interrupter to a base (not shown). Extending tube parts 101 on the housing part 9 fit into wide parts of holes 97 to insulate the bolts. The interrupter has a bimetal 51 arranged to act on a trip bar 49 common to all poles of the interrupter. A magnetic member 81 attracts an armature 83 on heavy overload and the armature also acts on the bar 49 which releases a latch 47 to allow an overcentre spring 39 to rotate a trip member 33 clockwise moving the spring overcentre to collapse a toggle linkage 29, 31 and open the contacts.
