Abstract

La presente invención se refiere a mejoras en un interruptor de circuito, caracterizadas en que el interruptor incluye una cubierta; una estructura de interruptor de circuito soportada en la cubierta; la estructura de interruptor de circuito tiene un par de contactos que funcionan para abrir y cerrar un circuito eléctrico; un mecanismo liberable, primer mecanismo manual que funciona cuando el mecanismo liberable está en posición para abrir y cerrar el mecanismo de disparo de los contactos en respuesta a sobrecargas de corriente superiores a un valor predeterminado para liberar el mecanismo liberable, con lo cual éste se mueve desde la posición enclavada hasta la posición disparada para abrir los contactos; el primer mecanismo manual funciona para mover al mecanismo liberable después de liberarlo, desde la posición disparada hasta la posición enclavada, un pestillo que funciona entre posiciones enclavada y desenclavada para enclavar el mecanismo liberable, un mecanismo de disparo que incluye un ajustador de capacidad externo, reemplazable, montado en forma desmontable en la cubierta; una interconexión que mantiene el mecanismo liberable en la posición disparada cuando se desmonta el ajustador de capacidad de la cubierta; una barra de disparo que se extiende entre el ajustador y el pestillo y que está bajo carga de resorte en la posición no disparada; la interconexión incluye un segundo dispositivo de accionamiento manual que funciona entre posiciones retraída y extendida para mover la barra de disparo a la posición disparada; la interconexión incluye tercer dispositivo de accionamiento manual que funciona entre posiciones de fijación y liberación de la barra de disparo, de modo que el pestillo no funcione en la posición de fijación.
