Product Description

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.)
