Production method of miniature circuit breaker

The invention provides a production method of a miniature circuit breaker, which is suitable for performing measurement precision verification, function testing and power-on aging during batch production of the miniature circuit breaker, and the measurement precision verification, the function testing and the power-on aging of a plurality of miniature circuit breakers are completed in the same box body capable of being sealed. After any miniature circuit breaker is fixed on the station where the miniature circuit breaker is located by using a fixing device, an electrifying device is connected with an incoming and outgoing line wiring terminal of the miniature circuit breaker, and the measurement precision verification, the function testing and the electrifying aging of the miniature circuit breaker are all completed on the station. The production method has the advantages that the measurement precision verification, the function testing and the power-on aging of the miniature circuit breaker are integrated an
