Abstract

The apparatus, such as a trip or differential trip, comprises, in the region of a terminal (1), a conductive piece (8) comprising a part (9) for connecting to the terminal, a foot (12) carrying the bimetallic strip, at least one zone of preferential deformation (10) being provided in order to prevent deformation being transferred from the plate to the said feet, the said element being lengthened by a switching electrode (22). <IMAGE>
