Abstract

1461814 Automatic circuit-breakers WESTINGHOUSE ELECTRIC CORP 18 March 1974 [27 March 1973] 11963/74 Heading H1N An automatic circuit-breaker similar to that of Specifications 1,461,491 and 1,461,813 has a releasable member which is part of its operating mechanism and is held by being urged against a latch lever 155 which is pivoted at 161 and normally held by its rolling friction engagement at 175 with a trip lever 153 pivoted at 168 and held by its engagement at 165 with a trip bar 83 which may be tripped on overload as in Specification 1,461,813.
