Abstract
A vacuum interrupter includes a housing having at least one annular ceramic insulating element which forms a vacuum chamber. A contact system has two contacts which are movable relative to one another. A capacitive element has two electrodes and a dielectric material disposed between the electrodes. The capacitive element is form-lockingly mounted on the insulating element and has a capacitance between 400 pF and 4000 pF. A high-voltage switching assembly including the vacuum interrupter is also provided.
