NH Fuse Base
NH fuse base is an industrial grade electrical protection and connection core component designed specifically for NH type knife type fuses. It is an indispensable basic component in low-voltage distribution systems, with the core positioning of "fixed support+reliable conductivity+fault isolation", providing dual safety protection for overload and short circuit in electrical systems.

Product Introduction
Unlike ordinary material fuse holders, NH fuse base uses high-purity copper as the main conductive material, deeply adapting to industrial grade high loads and complex working conditions, solving industry problems such as poor contact, severe heating, easy oxidation, and complicated maintenance of traditional fuse holders. They are widely used in global industrial power distribution, new energy, heavy equipment and other fields, and are the core selection option for "safety, efficiency, and durability" in engineering procurement, helping customers reduce project operation and maintenance costs, improve electrical system reliability, and adapt to voltage and specification requirements in different regions around the world.
core features
Material characteristics
The NH fuse base body is made of high-purity copper material, with a surface treated with nickel/chromium plating, which balances conductivity, corrosion resistance, and mechanical strength. Unlike ordinary copper alloys or iron products, it has a longer service life.
01
Structural features
Fuse copper holders and upper cover are designed with a split type opening and closing mechanism, with a built-in precision contact structure, equipped with precise positioning holes and installation slots, optional safety protection locks and insulation protection covers.
02
Performance characteristics
Contact resistance<50 μ Ω, mechanical life ≥ 5000 opening and closing cycles, rated current covering 63A-630A, rated voltage covering 500V, 690V, 1000V, some Fuse copper bases have protection level of IP20 or above, suitable for multi scenario requirements.
03
Adaptation features
Standardized size design, compatible with mainstream NH type fuses worldwide, can directly adapt to different brands and specifications of NH fuses without additional modification, reducing selection and replacement costs.
04
Compliance features
The production process complies with RoHS and REACH environmental standards, the materials are traceable, and international certification documents such as CE can be provided to adapt to procurement compliance requirements in different regions around the world.
05
production process
Raw material screening and comprehensive inspection: Purchase high-purity copper materials and supporting consumables, conduct comprehensive testing of material composition, conductivity, and mechanical strength before entering the factory, prevent the inflow of unqualified raw materials, establish a traceability system, and meet the compliance audit requirements of purchasers.
Precision stamping and precision machining: Fuse copper knife uses high-speed precision stamping equipment to form copper core components, strictly controlling dimensional tolerances; After stamping, stress relief annealing and high-precision polishing of the contact surface are carried out to ensure contact accuracy and low resistance performance.
Surface treatment and component assembly: Nickel/chromium plating is completed through a fully automated electroplating production line, and anti-corrosion standards are ensured through salt spray and coating thickness testing; Accurately assemble copper parts and insulation components, synchronously detect the contact resistance and insertion force of Copper holders for knife type NH fuse links, and ensure electrical and mechanical performance.
Full inspection and packaging storage: 100% completion of appearance, size, pressure resistance and other tests on finished Copper holder for knife type fuses, and mechanical life sampling verification (≥ 5000 opening and closing cycles); After cleaning, international transportation compatible packaging is used, and after passing inspection, it is stored and the inspection report is retained for easy traceability.
