Abstract

The invention relates to a thermal relay having bimetal triggers mounted in a housing and a multi-part transmission device which transmits the bimetal deflection from a bridge system via a trigger lever and further parts to an auxiliary switch and which is equipped with a bimetal rod, which cooperates with the trigger lever, for compensating the ambient temperature and a device for matching to the nominal current, said device being equipped, as a compensation and control unit, with a compensation bimetal rod (300) which is uniformly mechanically preformed in the shape of a circular arc. <IMAGE>
