Abstract: The gas-insulated HV switching device comprises a contact arrangement with two arcing contacts, one of which being designed as a contact tulip (21), an auxiliary nozzle (40) enclosing at least partially the contact tulip (21) and a tubular electrostatic shield (42), which protrudes along an axis (A) beyond a free end of the contact tulip (21). In order improve the switching performance of the switching device the tubular electrostatic shield (42) is electrically connected to the contact tulip (21) and is integrated in an electrical circuit comprising a current limiter (resistors 43, 44) and extending from the shield (42) through the current limiter to an end of the contact tulip (21) which is arranged opposite its free end.
