General
WCW1 series intelligent univeral circuit breaker (circuit breaker for short) applies at distribution network of AC 50Hz, rated voltage upto 600V( 690V), rated current 200A to 6300A, to distribute power and protect line and power supply equipments from fault demage of overload, under voltage, short circuit, single phase grounding. The circuit breaker has function of intelligent Protection with accurate selection to increase power supply reliability ths to avoid unnecessary power cut. It has open communication interface to make "Four-remote type Control" to fulfill requirements of control center and automatic system. The circuit breakers' impulse withstand voltage is 8000V when at altitude 2000 meter (Clarity according to standards of different altitude not over 12000V.)
