ABSTRACT:
A circuit breaker comprises a puffer volume (9) and at least one overpressure valve (16) for discharging gas from the puffer volume (9), if the pressure therein exceeds a given threshold. The overpressure valve (16) is formed by a piston (17) and a spring (19) as well as by a cavity (18) in the stationary support body (10) of the moveable contact assembly (2). The overpressure valve (16) is of compact and simple design, has low hysteresis and large cross-section.
