General

WCW1 series intelligent universal circuit breaker (ACB for short) applies at distribution network of AC50Hz, rated voltage upto 600V(690V) and below, rated current 200A to 6300A, to distribute power and protect the line and power supply equipments from fault demage of overload, under voltage, short circuit, single phase grounding. The ACB has function of intelligent protection with accurate selection to increase power supply reliability thus to avoid unnecessary power shut down. It has open communication interface to make "Four-remote Control" to fulfill requirements of control center and automatic system. The ACB's impulse withstand voltage is 800V when at altitude 2000 meter(clarify according to standards of different altitudes, not over 12000).
