ABSTRACT:
A current switching device comprises, in a box, at least one polar current path, disposed between two connecting terminals. The at least one polar current path comprising, in series, a break pole formed by at least one stationary contact and at least one mobile contact, a protective thermal tripping device having a bi-metal strip surrounded by a heater element and a protective magnetic tripping device having a coil wound around a coil form in which a mobile core slides. A wire of the coil being connected by an intermediate conductor to an end of the heater element. A wire of the heater element comprising a lower end which is substantially straight and without curvature, the lower end of the wire of the heater element being soldered to the intermediate conductor. The intermediate conductor being soldered to a substantially straight lower end of the coil wire. The two tripping devices being carried by a support which is slidably removable from the box.
