Application
L7, L7N and L9 series circuit breaker are used in lighting distribution system or motor distribution system for protection overload and short-circuit in the system. The product is neoteric 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 230V or two, three, four poles 400V circuit for overload and short-circuit protection as well as for unfrequent onand-off switching electric equipment and lighting circuit in normal case. The products comply with IEC 60898.
