Abstract
The invention provides a magneto-thermal device for overcurrent relays. The end of a core, whose axial position may be adjusted with respect to a mobile plate, placed opposite and pivoting about one end of the yoke, is secured against movement by a wedge which is guided in a groove belonging to a flange of the coil shell. This device may be used in any thermal relay where a stable and precise adjustment of the tripping current threshold is desired.
