Abstract: Aiming at the problem of standard circuit breaker applying in abnormal working conditions, this paper took the thermal magnetic moulded case circuit breaker as an example to analyze the impacts from DC circuit, frequency and change of high above sea level on the circuit breaker performance, giving countermeasures to be taken in design and application process aiming at circuit breaker temperature rise, short circuit analysis ability and tripping action characteristics etc possible performance changes, which ensures the operation reliability of standard circuit breakers under abnormal working conditions.
         Key words: moulded case circuit breaker; DC circuit; frequency; altitude; performance; impact
