Abstract

13,428. Michaelsen, P. June 7. Automatic circuit-breakers, outwardly resembling fuse-plugs, are constructed with a sliding contact c set by a push m into position to bridge spring contacts f, f<1>, and retained set by a spring latch i adapted to be tripped by a lever h which carries the armature of an electro-magnet b. The parts are mounted on a frame a fitted inside a porcelain plug p, from which the end of the resetting button protrudes to indicate that the circuit is broken.
