Parameters:
ACB-1-1000series intelligent air circuit breakers (hereinafter called ACB) are appliedfor the network circuit of AC 50Hz, rated voltage 400V,690V and rated current up to1000A. Mainly used for distributing energy and protecting the circuit and power supply device against short-circuit, undervoltage,single-phase ground fault etc. TheACB have intelligent protection function and the key parts adopt intelligent release.The release can make the accurate selective protection, which can avoid cutting offthe power and improve the reliability of power supply.Standard:IEC60947-2.
