Circuit breaker´╝Üunder normal operating conditions, the circuit breaker in the closing state (except for special applications), connected to the circuit. When the automatic control or protection control operation is carried out, the circuit breaker can be broken down or connected with the operation of the circuit under the control of the integrated protection device. The circuit breaker can not only break the normal load current, and can withstand a certain time of short circuit current (the normal operating current several times or even dozens of times), and can divide the short circuit current, cut off the fault line and equipment. Therefore, the main function of the circuit breaker is divided and connected circuit (including breaking and switching on normal current, breaking short-circuit current).
