    Abstract: Permanent magnet drive mechanism has few moving parts and high reliability. It is an innovative exploration to be used inresidual current reclosing circuit breaker. This paper introduces the working principle and structure of residual current reclosing circuitbreaker based on permanent magnet mechanism, the selection of permanent magnetic mechanism type and driving mode. The simulation andoptimization design process of closing mechanical characteristics and opening mechanical characteristics are carried out by using MaxweII software. By adjust the opening spring and contact spring make the contact pressure and breaking speed of the product reach an excellentcombination. Tests have shown that the designed reclosing residual current circuit breaker meets the design requirements of high breaking,high reliability and long life.
    Key words: residual current reclosing circuit breaker; residual current; permanent magnet operating mechanism; reliability
