Abstract
A circuit breaker protects an electrical low-voltage circuit. The circuit breaker has a housing with first and second connections on the mains side and first and second connections on the load side, and an isolating contact unit connected to an electronic interrupting unit. The isolating contact unit can be switched by opening contacts to prevent current flow or by closing contacts for current flow in the low-voltage circuit. The electronic interrupting unit is switched by semiconductor-based switching elements into a high-impedance state for preventing the current flow or into a low-impedance state of the switching elements for the current flow in the low-voltage circuit. A current sensor determines the level of the current of the low-voltage circuit. A controller is connected to the current sensor, the isolating contact unit and the electronic interrupt unit, such that a first measuring impedance is provided between the first and the second load-side connection.
