【 摘 要 】

On the base of accident investigation of metal parts failure in circuit breaker in recent years, reasons of material defects in metal parts, i.e. material composition, mechanical properties, microstructure and inclusion defects, were summarized in this paper. In the end, the corresponding control measures were proposed.
