Abstract (en)
[origin: WO0034969A1] The invention relates to an electric circuit breaker, notably for high or medium voltages. According to the invention, a damping unit (13, 21) comprising a space which is only partly filled with damping elements (18, 24) is arranged in the quenching gas stream. The damping elements move in a dissipative manner and thus cool and slow down the quenching gas stream.
