Abstract

958,707. Automatic circuit breakers. DORMAN & SMITH Ltd. Feb. 13, 1963 [March 8, 1962], No. 8919/62. Heading H2B. In a circuit-breaker generally of the type described in Specification 784,006, the bimetal tripping means 13 comprises two bimetal strips 14, 14a disposed front to back in parallel planes so as to act in unison. The two bimetals are of slightly different lengths and are clamped at one end to a support 15 and are connected at the other through separate braided leads 17, 17a to the contact member 18.
