Abstract
Improvements in thermal relays for control of electrical protection devices, of the type comprising a bimetallic sheet for each circuit to be controlled, with a heating resistance covered by the working current, and mounted so that one of its ends is displaceable for actuating, by means of a motion transmission which may comprise a tripping intensity adjusting device and means for compensating the ambient temperature, a safety element which maintains in the closed circuit position an electrical connection device that governs a contactor interposed in the work circuit, characterized essentially by the fact that the movement transmission comprises a rocker part articulated with a knife on a fixed fulcrum and provided with an arm that forms the securing organ, requested by one of its branches in the sense of retention and articulated by one of its ends to one of the extremities of a bimetallic plate compensating for the effect of the ambient temperature, whose plate is supported by an intermediate point and has its free end facing a stop of a displaceable organ and provided with stops facing the free ends of the bimetallic sheets heated by the currents of work.
