<p>A tripping device for a thermal protection relay, particularly a bimetal relay, has a pivoted U-shaped support bracket for a tripping lever, can be adjusted by means of an adjusting dog, and acts on a set of contacts. The U-shaped support bracket has a crosspiece which carries one end of U-shaped temperature compensation strip. The other end of the strip rests against the adjusting dog. The support bracket has support points for the support bracket and the tripping lever lying one behind another in the longitudinal direction of the bracket legs, starting at the crosspiece. This relay design results in reduced cost of assembly and in reduced overall relay size. Also, a heretofore required contact pressure spring for the temperature compensation strip is dispensed with.</p> |
