Abstract (en)

A switching device (1) for medium voltage applications comprising:- one or more electric poles, each comprising a movable contact (11) and a fixed contact (12) adapted to be coupled or uncoupled during a switching operation of said switching device;- an electromagnetic actuator (13) comprising a magnetic core (131), a coil arrangement (132) wound around said magnetic core and a movable plunger (133) operatively coupled to the movable contacts of said electric poles;- a control unit (14) for controlling switching operations of said switching device.Said electromagnetic actuator (13) comprises a conditioning circuit (135) adapted to modify the electric behaviour of said coil arrangement (132) when said conditioning circuit is electrically connected with said coil arrangement.Said conditioning circuit is electrically connected with or disconnected from said coil arrangement, when said movable contact (11) reaches or overruns a reference position (P) during a switching operation of said switching device.
