description The invention discloses a molded case circuit breaker performance monitoring method. The method comprises the following steps of obtaining corresponding closing and opening time, tripping and opening time and a tripping and opening time point; determining the shape of a relation curve representing the relation between the tripping speed and the tripping opening time point; determining a slope corresponding to each tripping and opening time point; determining tripping times and tripping frequency in a preset period; determining a consumption coefficient function; determining total opening consumption according to the consumption coefficient function; determining a performance attenuation coefficient; and determining the comprehensive health state grade of the molded case circuit breaker. The comprehensive health state grade of the molded case circuit breaker is determined according to the acquired related data, so that a user can conveniently carry out early warning and accurate positioning on the use conditio
