Abstract (en)
[origin: EP0540971A1] The present invention relates to a circuit breaker comprising, in a casing (1) filled with dielectric gas, in particular SF6, a first arc contact (2) connected to a first current outlet (3), a second arc contact (4) connected to a second current outlet (5) and which can move in a fixed cylinder (6) where, together with a piston (7), it forms a compression chamber (8). The first arc contact (2) and the piston (7) can move, the circuit breaker including means of actuation of the first arc contact (2) in the direction opposite to that of the displacement of the second contact (4) and of the piston (7) in the direction opposite to that of the displacement of the second contact (4). <IMAGE>
