Abstract

1468568 Automatic circuit-breakers BROWN BOVERI & CIE AG 29 Aug 1974 [6 Sept 1973] 37812/74 Heading H1N In a circuit-breaker similar to that of Specification 1,468,567, in which the bimetallic thermal tripping means 4, the electromagnetic tripping means 5 and the arcing chamber 6 are adjacent the same wall 2 of the switch housing, an extension of the yoke 15, 19, 30 of the electromagnetic tripping means forms an arcing horn 17 and an end wall 18 of the chamber 6. The contact operating mechanism is as described in Specification 1,468,569.
