Abstract: The invention relates to a medium voltage switching apparatus. The medium voltage switching apparatus includes one or more electric poles, each electrically coupleable with a corresponding electric line; for each electric pole, a fixed contact and a movable contact, the movable contact being reversibly movable between a decoupled position from the fixed contact and a coupled position with the fixed contact, the movable contact moving from the decoupled position to the coupled position during an closing manoeuvre of the switching apparatus and moving from the coupled position to the decoupled position during an opening manoeuvre of the switching apparatus; and actuating means adapted to actuate the movable contacts of the one or more electric poles. A control unit is adapted to select and carry out a selectable control routine in response to receiving an input signal at an input arrangement corresponding to the selectable routine.

Abstract: A switching device for low or medium voltage electric power distribution networks, the switching device comprising: at least an electric pole comprising a movable contact and a fixed contact, which are coupleable/decoupleable one to another; a circuit assembly, which comprises a chain of semiconductor devices adapted to switch in an ON state or in an OFF state depending on the voltage applied thereto, the semiconductor devices being electrically connected in series one to another in such a way that a current can flow according to a predefined conduction direction (CD) when the semiconductor devices are in an ON state. The circuit assembly comprises an input terminal, an output terminal and at least an intermediate terminal electrically connected with at least an intermediate electric node positioned between two subsequent semiconductor devices. The input terminal is electrically connected with the fixed contact: the input terminal, the output terminal and the at least an intermediate terminal are electrically coupleable/decoupleable with/from the movable contact when the movable contact reaches different positions during a movement towards/away from the fixed contact in such a way that different groups of semiconductor devices switch in an ON state or in an OFF state at different instants during the movement of the movable contact, depending on the position reached by the movable contact.
