YCW1 Air Circuit Breaker ACB


      YCW1 series intelligent air circuit breakers (hereinafter called ACB) are applied for the network circuit of AC 50Hz, rated voltage 400V, 690V and rated current between 630A and 6300A. Mainly used for distributing and protecting the circuit and power supply device against short-circuit, undervoltage, single-phase ground fault., etc. The ACB has intelligent protection function and the key parts adopt intelligent release. The release can make the accurate selective protection, which can avoid cutting off the power and improve the reliability of power supply.

      The products conform with IEC60947-1, IEC60947-2 standards.
