Abstract: 1,196,797. Automatic circuit breakers. GENERAL ELECTRIC CO. 6 Nov., 1967 [23 Nov., 1966], No. 50249/67. Heading H1N. The contact rod 68 of an automatic circuit breaker is decoupled from an operating mechanism 33 by current responsive means so that the contacts 18 can move rapidly to open position independently of the operating mechanism, providing a current limiting action. An operating handle 52 is coupled by overcentre mechanism to a pair of plates 45 pivoted at 46 to a frame. A fixed pin 75 provides end stops for the pivotal movement of plates 45. A member 73 is pivotally and slidably mounted on pin 75 and has a hooked part 84 biased into latching engagement with a roller 85, mounted on plates 45, by a spring 79. The member 73 is pivotally coupled to contact rod 68 at 71. Movement of plates 45 by handle 52 normally moves rod 68 between open and closed positions. In the event of a short circuit a solenoid 22 surrounding rod 68 moves the latter sharply to the left rotating member 73 about pin 75 against spring 79 so that member 73 is released by roller 85 and allowed to move independently of plates 45 to open the contacts. Spring 79 assists this movement. In the event of lower overloads a bimetal 54 or electromagnet 62 releases a latched arm 36 to trip the toggle linkage 33 and open the contacts in the conventional manner.
