The Circuit Breaker is a mechanical switching device, carrying and breaking currents under normal circuit conditions and also making, carrying for a specified time and breaking currents under specified abnormal circuit conditions such as those of short-circuit. In this study, we carried out the dynamic movement characteristic analysis for the spring operating mechanism of circuit breaker using MSC.visualNastran Desktop, and acquired relative response load time histories for the links and the levers of spring operating mechanism. In the future, we will perform the structural analysis of the links and the levers using MSC.Nastran, and the durability analysis using MSC.Fatigue. This study is the course for the structural and the durability analysis with spring operating mechanism of the circuit breaker
