Mini circuit breaker C45N series(DZ47 MCB)

Application: C45N series circuit breaker is used in lighting distribution system or motor distribution system for protecting overload and short-circuit in the system. The product is novel in structure, light in weight, reliable and excellent in performance. It has high breaking capacity, can trip quickly and it's installation uses with guide, it's case and items are adopted with high fire-retartant and shockproof plastics. The product, with long life, is mainly used in AC 50Hz/60Hz, single-pole 240V 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. This product conform to GB 10963, IEC898, BS3871.1.
