An exemplary breaker is disclosed with a gas drive for low-voltage, medium-voltage and high-voltage switching devices, in which disconnection can be generated via detonation capsules. To ensure that a low number of connection and disconnection operations in relation to the total operating duration of the circuit breaker is taken into consideration in design terms, without in the process reducing safety, exemplary embodiments include a piston/cylinder arrangement with a plurality of detonation capsules for generating a limited number of connection and disconnection operations in the cylinder in each of the two cylinder subareas which are separated by the piston.
