Abstract

Interruptor automático de circuito com dispositivo de disparo ativado por um contacto móvel. Onde a invenção refere-se a um interruptor (1) automático de circuito uni ou multipolar para uso em aplicações de baixa voltagem; o interruptor (1) de circuito inclui ao menos um primeiro contacto (10) fixo que é acoplado / desacoplado de um primeiro contacto (20) móvel; o contato móvel está conectado operativamente a um mecanismo (5) de operação que possibilita seu deslocamento; o interruptor (1) de circuito de acordo com a invenção inclui um dispositivo de disparo cinemático acionado por meio de um primeiro movimento de separação do contacto (20) móvel para fora do contato (10) fixo; o dispositivo de disparo cinemático inclui um membro operativo capaz de disparar o mecanismo (5) de operação o qual por sua vez age sobre o contacto (20) móvel assim determinando um segundo movimento de separação rápida até que a posição de disparo do interruptor de circuito seja atingida.
