Abstract

1,227,806. Automatic circuit breakers. GENERAL ELECTRIC CO. 6 Aug., 1968 [21 Sept., 1967], No. 37389/68. Heading H1N. The subject-matter is the same as that of Specification 1,227,805 but the claims relate to the thermal and magnetic tripping device. Another embodiment is described in which the bimetal strip acts on the magnetic member through a further bimetal to provide ambient temperature compensation.
