Product parameter

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.
