HW8 Air Case Circuit Breaker

 
Application
 
HW8 series intelligent air circuit breakers are applied for the network circuit of AC 50Hz, rated voltage 400V, 690V and rated current between 400A and 6300A. Mainly used for distributing energy and protecting the circuit and power supply
device against short circuit, under voltage, single-phase ground fault, etc. The HW8 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 to IEC60847-2, IEC60947-4 standards.
