RCBO, ELCB NXBLE
CHINT Made In China
AC Use Earth Leakage Circuit Breakers 6~63 A
Miniature Circuit Breakers for AC Current circuits, offering terminal distribution installation protection
The NXBLE-63 is a miniature circuit breaker that offers AC current circuit protection. It protects circuits against short-circuit currents and overload currents.
NXBLE-60 mini circuit breaker is used in lighting distribution system or motor distribution system for protection overload and short-circuit in the system. The product is neoteris in structure, light in weight, reliable and excellent in performance. It has high breaking capacity, can trip quickly, and its case and items are adopted by high fire-resistant and shockproof plastics. The product with long life, is mainly used in AC 50Hz/60Hz single-pole 240 or two three, four-pole 415V circuit for overload and short-circuit protection as well as for unfrequent on-and-off switching electric equipment and lighting circuit in normal case. The products comply with IEC 60898 & BS 3711.
Compliant with IEC60898, IEC61009
Available in 1P+N, 2P 3P, 4P and 3P+N
B, C, D tripping curve
Up to 500V AC.
NXBLE MCB combines the following functions:
b Protection of circuits against short-circuit currents
b Protection of circuits against overload currents
b Control
b isolation
