  • Arrangement and method for switching high currents in high-, medium- and/or low-voltage engineering
    Patent number: 11417479
    Abstract: An arrangement and a method for switching high currents include at least one vacuum switching path and at least one rated-current contact switching path. The at least two switching paths are electrically connected in parallel. One current path for a rated current is routed over at least one rated-current contact of said rated-current contact switching path, and a parallel current path for a short-circuit current is routed over at least one contact of a vacuum tube of the vacuum switching path.
    Type: Grant
