PERFECCIONAMIENTOS INTRODUCIDOS EN UNA DISPOSICION DE CIR- CUITO DE POLOS MULTIPLES.

摘要

A multi-pole circuit breaker system includes a plurality of individual circuit breakers and at least one tripping action transfer device disposed between adjacent circuit breakers. The tripping action transfer device includes a lever pivotally supported at one end and carrying a rod shaped transfer member at its other end. The transfer member extends into the interior of the housings of adjacent circuit breakers and cooperates with their tripping mechanisms. A tripping operation of one circuit breaker engages the transfer member and causes actuation of the tripping mechanism of the adjacent breaker to initiate simultaneous tripping thereof.
