In this paper, the main function of a circuit breaker is to open up a circuit for a pre-defined time so as to prevent a sudden surge in current that could damage the equipment due to high heat is discussed. The equations of motion derived in this paper can predict the closing, opening of spring type operating mechanism in predefined time as well as be used to compute dynamic response of the moving contact. Using the optimized switch gear mechanism, the atlas of all feasible mechanisms for the spring-actuated controlling system of a circuit breaker has been synthesized.
