Application
DW45 series intelligent air circuit breaker is mainly used as the main switch in the low voltage distribution switchboard. DW45-6300 is available with a rated frame current of 6300A and a rated current from 630A to 6300A. Apart from intelligent air circuit breaker, we can also supply Miniature circuit breaker(MCB), mouled case circuit breaker(MCCB), Earth Leakage Circuit Breaker(ELCB,RCD,RCCB,RCBO), Contactor, Distribution Board, Cabinet, Relay, Fuse and so on. With ISO9001, CCC, SEMKO,CE, SAA certificate and CB test report, these products are exported to many countries that include Russia, Turkey, England, Australia, France, Brazil, Peru, Syria, Saudi Arabia, Jordan, India, Malaysia and more.
