Original Abstract Submitted

Some embodiments are directed to a hybrid circuit breaker, including a mechanical bypass switch and a voltage source arrangement disposed in an outer conductor path. A first semiconductor circuit arrangement can be connected in parallel to the mechanical bypass switch and the voltage source arrangement. The hybrid circuit breaker can include an electronic control unit and a current measuring arrangement, and a first snubber arrangement connected parallel to the first semiconductor circuit arrangement. The first snubber arrangement can be connected to the neutral conductor path, the hybrid circuit breaker being embodied to limit an electric current at the first outer conductor terminal to a predefined current level, and the control and driver unit being embodied to switch-off the mechanical bypass switch and activate the first semiconductor circuit arrangement to limit the electric current at the first outer conductor terminal.
