Abstract

Perfeccionamientos introducidos en los dispositivos eléctricos monobloque de tres funciones: es decir, corte general, protección contra la tensión de contacto y protección contra las sobretensiones, aptos para alimentar, por lo menos, dos líneas de salida y que comprenden un interruptor general en la línea de entrada, un diferencial y dos o más interruptores magneto-térmicos, uno para cada línea, caracterizados porque el aparato diferencial en caso de dispersiones de corriente hacia tierra acciona un disparador que hace saltar simultáneamente todos los interruptores magneto-térmicos, comprendiendo el aparato diferencial una palanca o pulsador para volver a montar el disparador, estando dotados los interruptores magneto-térmicos cada uno de una palanca o pulsador para la conexión de las líneas de salida.
