摘要： An electrical switching device is provided for interrupting an electrical connection. The device has a switching chamber and two contact pieces being arranged directly in the switching chamber or in an encapsulated housing arranged in the switching chamber and configured to be gas-tight in relation to the switching chamber. The contact pieces are movable relative to each other to bring about a switching action. A fluid insulation medium is also provided, which is arranged in the switching chamber or in a storage volume which can be connected to the switching chamber. The switching chamber or the storage volume has an outlet for letting out the fluid insulation medium. A filter is provided at or adjacent to the outlet, the filter configured to filter gaseous components of the insulation medium, or the reaction products thereof, conducted through the outlet.
