Abstract

1387990 Automatic circuit-breakers CMC CHARLES MAIER & CIE 20 Nov 1972 [22 Nov 1971] 53559/72 Heading H1N In a multiple circuit-breaker in which the parts of each pole are carried between two walls of insulating material and include an operating lever 3, 4, the levers are coupled together for actuation by a handle 27, which, on assembly, is slid in the direction of the common axis of the levers over axially grooved substantially semicylindrical ends 3 of the levers, the handle having a hollow semi-cylindrical part 5 with a rib 7 which engages in the grooves 6 and respective lips 8 on the straight edges of the part 5 engaging the edges of the levers.
