1. Application

MW1 series intelligent universal circuit breakers/air circuit breaker (hereinafter called ACB) suits the circuit of AC 50Hz, rated voltage 660V(690V) and below, rated current 400A-6300A distribution net and it's used to distribute and protect circuit. It could also protect current supply device against overload, under-voltage, short current and single-phase earthing. MW1 ACB has intelligentized protecting system, accurate selectivity protection and it could increase power distribution reliability and avoid unnecessary power failures. At the same time, MW1 series also has open communication interface which could realize “Four Remote”, remote checking, remote regulating, remote control and communications in order to satisfy collective control center and automatic system. The impulse withstand voltage of this ACB is 8000V in altitude of 2000m(diffirent mounting altitude, the impulse withstand voltage is differ, pls refer to the standard, the Max. should be more than 12000V).
Varied intelligent controller offers various functions. the breaker has disconnecting function if does not have intellighent controller and sensor, its corresponding symbols is shown as
