Abstract (en)

[origin: EP1148527A1] The circuit breaker construction has a first contact (1) moving longitudinally inside an arc breaking chamber (2) with gas compressed by a piston (8). Piston movement is by a telescopic connection (11). The length of displacement of the piston in the compression phase is equal to the length of movement of the first contact in the first compression phase.
