- the Naturallass ⁇ Sonen between the hollow contact volume, the intermediate volume and optionally the additional volume are mutually offset on the circumference.
- the passage openings between the additional volume and the exhaust volume are arranged offset from each other on the circumference and / or in the axial direction. As a result, meandering as well as spiral exhaust paths are specified, the residence time of the exhaust gas in the exhaust area is increased and the heat output of the exhaust gas is improved. Further, the holes may be closed by means of perforated plate-like apertures to produce a plurality of radially directed gas jets or Gasj ets that bounce on the opposite wall, swirling at the impact points and thereby cool the hot gas intense.
- the cooling-improving intermediate volume is arranged in the exhaust area on the drive contact side. A second intermediate volume may additionally be present on the fixed contact side. Overall, in addition to the hollow contact volume, the exhaust volume and the switching chamber volume, at least one further intermediate volume is needed in the circuit breaker in order to achieve efficient exhaust gas cooling.

- the cooling device comprises a plurality of tubes arranged concentrically in the gas outflow channel, each of which has diametrically opposite outflow openings, so that the switching gases must rush through a labyrinthine path with numerous deflections during laminar outflow and have to coat large surfaces of the cooling tubes. With this arrangement, therefore, essentially the outflow path is lengthened and the cooling surface in the exhaust is enlarged.
- the outflow openings are wide, in order to keep the back pressure of the switching gas low.
- the flow channels between the cooling tubes are narrow to provide the switching gas much cooling surface available. Overall, the flow is kept in the laminar range and the cooling of the switching gas is carried out by laminar convective heat transfer into the cooling tubes.

- the perfused body serves primarily for jet formation and does not need to have any cooling effect on the switching gas itself.
- the improved exhaust gas cooling is achieved in that the heat energy is released by a turbulent heat transfer from the vortices in the baffle and that a highly efficient heat dissipation is made possible by the baffle as part of the switching chamber or as a mounting part on the switching chamber housing.
- the heat energy can be stored in the baffle or forwarded to a heat sink thermally connected to the baffle.

Even highly ionized, not yet solidified dielectrically switching gas can be cooled at the lying on potential baffle.
- the embodiment according to claim 2b has the advantage that the Sehaltkarmmergeophuse total or at least on a switch contact side is used as a large-volume heat sink for the thermal energy absorbed by the baffle wall.
