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.)
