Abstract
The present invention relates to a medium- or high-tension circuit breaking having abutting arcing contacts and comprising a casing filled with a gas having good dielectric properties and containing a stationary first abutting contact and moving equipment including a first tube capable of being displaced by a drive rod and a semi-moving tubular second abutting contact. The annular end of the first tube carries a ring of contact arms that slide on the first abutting contact and that carry respective arcing contact blocks at their ends and respective permanent contact swellings proximate to the arcing contact blocks. A circuit breaker is thus provided which withstands the effects of arcing particularly well.
