Abstract (en)
[origin: EP1148528A1] The electrical circuit breaker has a first arc contact (1) in a self extinguishing chamber with gas under pressure and a second contact arc (5) following an axial direction with respect to the first arc. There is an interior enclosure (4) with orifice input (6) to the arc area, and a second enclosure with orifice input (7). The orifice and volume enclosures are connected by extinction channels (12,13). The second contact is placed between the end of the contact arc and the permanent current contact. There is an interconnection channel (9) connected by a valve (10) allowing gas in both directions.
