NLM2 Series intelligent adjustable molded case circuit breaker is new developed breakers following with NLM1 series, which adopts international advanced design and manufacturing technology.
The breaker has features: compact structure, small size, high breaking capacity, short electric arcing and complete internal accessories.
And functions such as overload long-delay inverse time lag, short-circuit short-time delay fused time lag and short-circuit instantaneous operation. And parameter uses DIP switches setting, which is convenient and intuitive.
Users can setup by themselves and compose required protection performance according to release types. It is easy to implement selective protection, making breaker equipment environment more reasonable in Power Distribution network.
