Abstract (en)

[origin: WO9944213A1] The invention relates to a high voltage power circuit breaker with two arcing contacts (1, 2) situated coaxially opposite each other and an insulation nozzle which is dammed by the first arcing contact (1) when switched on. The first arcing contact (1) has a shaft (8) with an enlarged diameter and an end piece (7) with a reduced diameter. Said shaft (8) dams a through channel (6) of the insulation body (3). The through channel (6) is cylindrical in form over a shorter length than the length of the end piece (7). The stream of arc extinguishing gas is therefore introduced when the end piece (7) is drawn back into the through channel (6).
