Miniature Circuit Breaker KNB1-100(NC-100)

     Mini Circuit breakers, also named as the air switch which have a short for arc extinguishing device. It is a switch role, and also is a automatic protection of low-voltage electrical distribution. Its role is equivalent to the combination of switch. Fuse. thermal relay and other electrical components. It mainly used for short circuit and overload protection. Generally, According to the poles, mini Circuit breaker can be divided into 1P , 1P+N , 2P, 3P and 4P.

    KNB1-100 series Miniature Circuit Breaker is mainly used in the line of AC 50/60Hz, rated working voltage to 240V/415V, and rated current to 100A as protection against overload and short-circuit.
