Abstract
Un mecanismo protector eléctrico para el arranque de motores en general, incluyendo un disyuntor multipolar y un contactor multipolar electromagnético, conectado en series eléctricas con dicho interruptor automático (disyuntor), una caja incluyendo una base conteniendo dicho disyuntor y dicho contactor montado en ella en la que el mencionado contactor está en un extremo del disyuntor; la caja mencionada incluye una tapa delantera que se abre para dicho, disyuntor y dicho contactor. El interruptor automático comprende un sistema electromagnético sensible de máxima, que incluye una bobina que opera individualmente para cada polo de dichos disyuntores; este sistema protector está caracterizado porque cada una de esas bobinas es accesible para ser retirada y colocada desde la parte anterior de dicha caja abriendo su tapa.
