Abstract (en)
[origin: EP0146424A1] 1. Self blow-out electric circuit breaker with arc rotation depending on a magnetic field, comprising insides a sealed housing (10), filled with sulphur hexafluoride, an arc formation chamber, in which is arranged a pair of separating contacts (16, 18) and an arc extinguishing chamber in which is arranged a pair of ring-shaped electrodes situated face to face in order to constitute annular tracks (28, 32) for the migration of the arc to be extinguished, and a magnetic blow-out device (34, 56) by rotation of the arc on said annular tracks (28, 32), characterized in that the movable contact of said pair of contacts is extended without discontinuity by an arcing horn (24) extending between the arc formation chamber and the extinguishing chamber and joining with one (28) of said annular tracks, the other annular track (32) being associated with the stationary contact (16), a current supply conductor (23) constituting a blow-out loop of the arc in the direction of the annular tracks (28).
