Abstract (en)
The unit has two contact parts concentrically arranged with respect to a central axis, where one of the parts includes an insulation nozzle (4) for blowing out of arc. A holding device includes a clamping device with holder rings for fixing the nozzle to components e.g. buffer cylinder and insulating electrode, by clamping. The clamping device includes a washer (10) for thermal and mechanical protection of a spring (11). An independent claim is also included for an electrical switching device including a breaker unit in a power grid.
