Abstract
A circuit breaker protects an electric low-voltage circuit, and has: a) the function of ascertaining a level of a differential current of the low-voltage circuit, b) a mechanical separating contact unit so that an opening function of contacts is switched to prevent a current flow or a closing function of the contacts is switched for a current flow in the low-voltage circuit, and c) an electronic interruption unit which is connected to the mechanical separating contact unit in series and which, as a result of semiconductor-based switch elements, is switched to a high-ohmic state of the switch elements to prevent a current flow or a low-ohmic state of the switch elements for a current flow in the low-voltage circuit. The ascertained level of the differential current is compared with a differential current threshold and if the current threshold is exceeded, the current flow in the low-voltage circuit is prevented.
