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.
