Abstract
La presente invención se refiere a mejoras en una unidad térmica ajustable de disparo para interruptores de circuito, con el interruptor de circuito comprendiendo contactos principales separables, barra de disparo rotatoria con una porción de superficie, mecanismos operables interconectados mecánicamente entre los contactos y la barra de disparo, caracterizadas porque la barra de disparo tiene un movimiento angular con relación a la porción de superficie para hacer que los contactos se abran ante un determinado valor de corriente eléctrica, dicha unidad de disparo incluye un ajustador térmico de disparo, separable de la barra de disparo de manera que se pueda ajustar la disposición de translación de la barra de disparo con relación a la unidad de disparo, provista de una manija rotatoria con la cual se ajusta la unidad de disparo, y que coopera con un tornillo de detención ajustable que influye en la manija para ajustar el calibre de la unidad de disparo, causando que los contactos principales se abran ante valores diferentes de corriente eléctrica.
