Method of executing a self-test of an alternating current circuit breaker, with a plurality of functional blocks. A processing unit is connected to first and second galvanic separation switches (SW2, SW3), a bypass switch (SW1) and a semiconductor switch element (IGBT), and is arranged to execute a self-test of the circuit breaker for each of the plurality of functional blocks, wherein the sequence and timing of the test of each of the plurality of functional blocks is programmed in and executed under control of the processing unit. Entering a failure mode of the circuit breaker is done upon detection of a failure status in any one of the functional blocks. |
