Abstract (en)
[origin: WO0203411A1] A low-voltage circuit breaker (1) has an arc-extinguishing chamber (2) and a switching gas damper (4) which consists of two partial bodies (6, 7) that are displaceable in relation to each other. One (6) of the partial bodies (6, 7) is fixed to the circuit-breaker (1), while the other (7) is pre-stressed against the first partial body (6) with an elastic restoring force (spring 12). The switching gases that are discharged from the arc-extinguishing chamber (2) are contained inside (8) the switching gas damper (4) until the relative displacement of the partial bodies (6, 7) forms a flow outlet through which the switching gases can escape.
