Abstract This paper introduces the phenomenon of pilfering in the operation of a universal air circuit breaker for marine use. The action of the protective device, the middle relay of the control loop, the anti-interference of the control cable, and the insulation performance of the secondary terminal are checked. The reason for the trip is found through comprehensive analysis, and certain measures are taken to reform to avoid the occurrence of the switch jumping again.
