Abstract: A circuit breaker protecting an electrical low-voltage circuit includes a mechanical separating contact operable by a mechanical handle switching a contact opening function preventing current flow or a closing function for current flow. An electronic interruption unit connected to the mechanical separating contact unit in series on the circuit side, as a result of semiconductor-based switch elements, is switchable to a high-ohmic state of the switch elements preventing current flow or a low-ohmic state thereof for current flow. An ascertained current level is compared with current thresholds and, if exceeded, initiates prevention of current flow in the circuit. When contacts are closed and the interruption unit is in the low-ohmic state, the interruption unit switches to the high-ohmic state upon initiating a voltage-reduced state of the circuit. After discontinuing the voltage-reduced state, the interruption unit switches back to the low-ohmic state.
