Abstract
A circuit breaker protects an electric low-voltage circuit. The circuit breaker has a housing with grid-side connections and load-side connections for conductors of the low-voltage circuit and a series circuit containing a mechanical separating contact unit and an electronic interruption unit. The separating contact unit is paired with the grid-side connections, and the interruption unit is paired with the load-side connections. The mechanical separating contact unit has a handle for closing and opening contacts. A current sensor is arranged in a conductor path between the separating contact unit and the interruption unit, for ascertaining the level of the current of the low-voltage circuit. The circuit breaker is configured such that when current thresholds and/or current/time thresholds are exceeded, a process for preventing current flow in the low-voltage circuit is initiated. A power supply is connected to conductors of the low-voltage circuit between the grid-side connection and the separating contact unit.
