After thorough research into low-voltage apparatus and NJDQEI MCCB product lines we made a proper product strategy for NJDQEI’s new product line development. Meanwhile, we conducted the research of each detail of the product, from its expansibility, user-friendliness, and safety to the recognition of product image. At present the product has got to massive production stage with good market reaction and has become the benchmark of the 4th generation intelligent breaker in the industry.  Through unified Product Identity factors we’ve strengthened brand recognition. The design stressed product safety, expansibility, user-friendliness etc. and paid much attention to details. All this contribute to the present professional, safe and high-quality product image.
