    Abstract: Because part users poorly understood the universal circuit breaker, there existed abnormal conditions in actual use procedure. Combining with the practical cases, this paper carried out analysis and process for the use malfunction of universal circuit breaker from the aspects of irregular design of power distribution switchgear cabinet, irregular site operation, misoperation of site service and maintenance personnel and improper model selection of circuit breaker etc. It is pointed out that the design should be thoughtful. The site operation should accord with the corresponding electrical code requirement and the circuit breaker shouldn’t be changed and took down under the conditions of unfamiliar products.
