    Abstract: A switching apparatus (1) for LV or MV electric systems.
    The switching apparatus, according to the invention, comprises one or more electric pole units, each comprising a fixed contact and a movable contact.
    Each electric pole unit comprises a motion transmission arrangement adapted to transmit mechanical forces to move reversibly the movable contact. Said motion transmission arrangement includes a conductive motion transmission member coupled to the movable contact.
    Each electric pole unit comprises a first pole terminal and a second pole terminal for coupling with a corresponding first line conductor and second line conductor, respectively.
    The first pole terminal is in electrical connection to the fixed contact while the second pole terminal comprises a first coupling region in electrical connection with a second coupling region of the conductive motion transmission member.
    According to the invention, each electric pole unit comprises a shielding element formed by a conductive hollow body and arranged in a relative fixed position with respect to the second pole terminal and the motion transmission member.
    The shielding element is arranged in such a way to surround, at least partially, the first coupling region of the second pole terminal and the second coupling region of the conductive motion transmission member. In this way, the first coupling region of the second pole terminal and the second coupling region of the conductive motion transmission member are positioned in an internal volume of the shielding element.
