Recently, remote-controllable actuators for circuit breaker (CB) have attracted attention for the smart grid electric power system. In this study, diverse kinds of remote-controllable electromagnetic actuator for CB are precisely investigated to give a guideline for the selection of the effective actuator according to numerous voltage level of CB. In case of a low-voltage level of CB, the separated permanent-magnet actuator (SPMA) is verified in this research as the most suitable actuator through the comparison with diverse electromagnetic actuators. The SPMA is designed for the 225AF moulded case CB by using the proposed optimisation method, which the authors termed as a multi-step optimisation strategy.
