Abstract

1350888 Automatic circuit-breakers J R McCAUGHNA 19 April 1971 [6 Dec 1969] 28700/69 Heading H1N A multi-unit circuit-breaker comprises a plurality of circuit-breaker units of the kind disclosed in either of Specifications 1,306,221 and 1,309,384, with an element spanning all the units and effective to cause opening of all the units in response to the actuation of any one tripping device. This element may interconnect the operating handles, the armatures or the latches.
