Find Verified Electric Relays Suppliers, Manufacturers and Wholesalers

Fnad Electrical Appliance Plant, established is located in Ningbo, China. It is 2km away from Geely Automobile Industrial Park. It is a science and technology enterprise integrating with R&D, manufacture, trade and service. The Plant has focused on motor protection for more than years. It is specialized in applications of single-chip microcomputer technology in the fields of industrial control, power electronics and automobile electronics.
Our main products include motor protectors, phase failure protectors, phase sequence protectors, volt-ammeters, surge protector, temperature controllers, etc. we have an in-depth study in prevention of occurrence of phase failure, phase sequence, overload, under-load, overvoltage, under-voltage, three-phase imbalance, over-current and similar abnormalities in customersâ?? equipments and provide such solutions as prevention, alarming and equipment protection. It supports major elevator plants, thermal power plants, automobile plants, crane factories, textile mills, refrigerating plants and chemical plants and provides solutions for them. Some products have passed CE certification and ROSH environmental certification of European Union.

We endeavor to make the company to be listed in Hong Kong in 2020. Welcome to visit and communicate with us.
