Abstract
A control module with interrupt function for an electric circuit breaker has a voltage input for a control voltage, an output carrying the control voltage to which output an interrupter for the circuit breaker can be connected, an input for the control voltage fed back from the interrupter, a terminal for the circuit breaker, said terminal being connected to the input, and a measuring unit for measuring current and/or voltage at the input and at the output. An electric protection system has an electric circuit breaker, an interrupter and a control module. In a method for operating a control module, the circuit breaker is supplied during its operation with voltage and current via the terminal, the measuring unit determines currents and/or voltages at the input and the output, the control module transmits currents and/or voltages to an evaluating unit for determining a characteristic value which correlates to the quality of the interrupter, the evaluating unit determines, from currents and/or voltages, a characteristic value which correlates to the quality of the interrupter.
