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