Abstract

Un mecanismo de desconexion (140), que incluye dos accionadores de desconexion, a saber un accionador de desconexion bimetal (144) y un accionador de desconexion magnética (142), que actuan sobre un émbolo (L60). Una guía de émbolo (162) guía el movimiento del émbolo a lo largo de una trayectoria de línea vertical de desplazamiento. Cada accionador de desconexion es capaz de mover el émbolo independientemente del otro accionador de desconexion para provocar que el interruptor se desplace en respuesta a la deteccion de una falla térmica o de una falla magnética.
