Abstract

Perfeccionamientos introducidos en un disyuntor multipolar que comprende un par de contactos cooperantes en cada polo, un mecanismo de accionamiento que incluye un brazo normalmente enganchado y liberable que, cuando es liberado, se mueve para efectuar la apertura simultanea de los contactos en todos los polos, un miembro de enganche cooperable con el brazo liberable para mantener al último enganchado mientras el miembro de engancha esta en una posición de enganche del mismo, y medios de disparo que incluyen en cada polo un elemento bimetálico para efectuar la liberación del brazo liberable por dicho miembro de enganche en respuesta a condiciones predeterminadas de corriente de sobrecarga.
