Abstract

An electrical circuit breaker device that includes an insulating box, an actuating member mounted in said insulator box, a support member mounted in said insulator box, said support member comprising an elongated strip of metallic material, said metal strip having an intermediate portion fixedly mounted on said insulating box and a first end part separated from said intermediate part, an elongate sheet of bimetallic material having one end thereof fixedly mounted on said first end portion of said metal strip and having its other end in application with said actuating member, characterized by means in said housing for adjustably locating said bimetallic sheet, provided with means for exerting a force on said first end of said metal strip to bend said metal strip at a point of bending between said first end portion and said part intermediate, said strip having a cross section network At said bending point, said metal strip is substantially bent only at said bending point during an adjusting movement of said first end, and means for heating said bimetallic sheet in accordance with the electric current passing through it. said device.
