Abstract (en)
[origin: WO0108186A1] The invention relates to a vacuum interrupter for circuit-breakers. The aim of the invention is to reduce the contact pressure force. To this end, the contacts (1, 2) of the vacuum interrupter are configured in such a way that an inner contact area (9) is situated inside an outer, arc-extinguishing contact area (7). Said inner contact area consists of several spring contact studs (11) that are situated adjacently to each other on a divided circle.
