Abstract:
1. A device for measuring the electric current flowing in an electrical equipment unit, said device being housed in a case for fitting on a mounting support, said case having a plurality of holes therethrough, the device comprising: a plurality of conductors, one of which passes through each of said holes, respectively, thereby comprising terminals of the device; wherein at least one of the terminals of the device comprises a magnetic core at least partially surrounding said device terminal and a secondary measuring coil wound between two adjacent end portions of said magnetic core thereby defining at least two air gaps each of which is surrounded by a secondary measuring coil and said magnetic core, each said coil for generating a signal representative of the current flowing in an electrical equipment unit; wherein said device is fitted inside a first case for being removably fixed in a second case of the equipment unit; and wherein the first case comprises two pins salient from an outer surface of said first case, for voltage tapping on contact strips of terminals of the equipment unit via first ends of said pins, and for securing the first case with respect to the second case, said pins being electrically connected via their opposite ends to voltage measuring means.
