Abstract

262,342. Harbour, R. H., and Walton, J. R. Aug. 25, 1925. Automatic circuit-breakers; electric cut-out systems.-To protect a polyphase electric motor, no-volt magnets e, f, g in the respective phases of the supply trip a holding-on latch t of a line switch a<1>, b<1>, c<1> when the current fails in any or all of the phases. The device may be associated with an overload release as described in Specification 263,408.
