    Abstract: The invention relates to a high-voltage circuit breaker having an interrupter unit which is surrounded at a distance by a gas-tight housing (16) filled with a smothering gas. The interrupter unit comprises two arcing contacts (1, 2) between which an arc produced when a current is interrupted is blown at by a blowing device (5) emitting a smothering gas. Thereafter said gas flows at least partly in the axial direction of the arcing contacts (1, 2). According to the invention a flow deflection device (9, 10, 11) which is different from the blowing device (5) is provided for in the flow area of the smothering gas which deflects the smothering gas flow radially outwards by more than 90 DEG .
