A method of executing a self-test of an alternating current circuit breaker involves executing a self-test of the circuit breaker for each of a plurality of functional blocks, wherein a sequence and timing of the executing a self-test for each of the plurality of functional blocks is programmed in and executed under control of a processing unit, and entering a failure mode of the circuit breaker upon detection of a failure status in any one of the functional blocks. The alternating current circuit breaker includes a live line between a live supply connecting terminal and a live load connecting terminal, and a neutral line between a neutral supply connecting terminal and a neutral load connecting terminal, the plurality of functional blocks, and the processing unit, which is connected to the first and second galvanic separation switch, the bypass switch and the semiconductor switch element. |
