KY2NB series intelligent miniature circuit breakers have the characteristics of advanced and reasonable structure, reliable performance, high breaking capacity, and beautiful appearance. The shell material is composed of high-quality impact-resistant and high-flame retardant materials. It is suitable for indoor, AC 50Hz, rated voltage 230V, three-phase 400V, and rated current not exceeding 100A. It is mainly used for low-voltage terminal power distribution in industrial, commercial, civil buildings and infrastructure in buildings and similar places. Leakage, overload, short circuit, over-under-voltage, over-heating, and lack of equal protection can also be used for infrequent on-off operations. The leakage circuit breaker with the rated residual operating current less than 30mA can provide protection for personal electric shock.
