New Schneider ACB Frame Circuit Breaker NW08H1 3200A 1000A 1600A 2000A 5000AMPS 4P/3P
air Circuit Breaker Drawer Type
The MKW65A series intelligent air circuit breaker (hereinafter referred to asthe circuit breaker) is applicable to the power distribution network with Ac50/60Hz, rated working voltage of AC 400v, 690V & 1140V and rated workingcurrent of 200A~4000A to distribute power and protect circuits, so that theequipment is protected from overload, short circuit, under-voltage, earth (leak-age) and other faults. With communication and intelligent protection functions,the circuit breaker can accurately realize the selective protection between theupperand lowerlevels, improve the power supply reliability and avoid unneces
sary power failure.The CKW65A-1600M/2500M /3200M types are special ones for State Gridstandardized cabinets.The circuit breaker also has an isolation function .“The circuit breaker meets the standards: GB/T 14048.2 and lEC 60947-2.
