A cut-off arrangement is also provided in the output current path and has a first electrode and a second electrode. The second electrode has a recess in which at least part of a gas generator is arranged. The recess is covered by a cover. When the cut-off arrangement responds, an additional volume for accommodation of expanded gas is provided upon demand, in addition to an arcing area provided in the interior of the cut-off arrangement.
