EBB Moulded Case Circuit Breaker
EBB Moulded Case Circuit Breaker

 
Application
The HBB series moulded case breaker applies to breaking and making operation in AC 50/60Hz, rated operation voltage 690V or less and rated current up to 1600A circuit. It can distribute electric energy in circuit, work as the overload of
wiring and power supply equipment, or as the protector of short circuit and under voltage. Additionally, this breaker can switch line and start motor unfrequnently. The other characters of the products are: small size, large contact spacings,
high capability of break-make, and short arcing distance, this performance is better than that of CM1series. Therefore, it is the new product replacing the older generations of home products-DZ10, DZ20 and H series moulded case breakers,
This performance is as well as ABB. S series circuit breaker. The product complies with the standards of IEC90947-2, GB1408.2-2001.
