    摘要： The invention relates to a two-stage shut-off device for a varistor (1), comprising a first switching unit (2), which is suitable to be switched in the event of a fault, wherein the first switching unit (2) is an opening contact which is connected in series to the varistor (1), a PTC thermistor (3) that is connected in parallel to the first switching unit (2), wherein the resistance of the PTC thermistor in the cold state is smaller than the comparable resistance that would form at the first switching unit (2) in the event of a switch arc, and a second switching unit (4), wherein the second switching unit (4) is an opening contact that is connected in series to the varistor (1), wherein the second switching unit is controlled by the PTC thermistor (3).

    摘要： The invention relates to a method for disconnecting an electrical connection of an overvoltage protection element (12), intermediately connected between two connecting points (16, 18), from one of these connecting points (16), having a first feed path (20) which electrically connects a connection of the overvoltage protection element (12) to one of the connecting points (16), wherein in the first feed path (20) a first opening switch (24) is arranged which is opened by being triggered by a change in pressure and/or a change in temperature of the overvoltage protection element (12). There is provision that when the first switch (24) opens, switching over occurs to a second feed path (22) connected in parallel with the first feed path (20), wherein in the second feed path (22) a second opening switch (26) is arranged for safely disconnecting a follow current, and wherein the opening of the second switch (26) takes place with a delay with respect to the opening of the first switch (24). The invention also relates to a corresponding circuit arrangement (12) and to a switching device (40) for use as a second switch (26) in the method.
