Copper Fuse Clips, Copper Fuse Clamps

Copper Fuse Clips and Copper Fuse Clamps

We are premier manufacturers, suppliers, and exporters of Copper Fuse Clips and Copper Fuse Clamps from our ISO-certified press shop in India. Our copper fuse clips are precision-pressed components used to hold and connect cylindrical cartridge fuses in low-voltage electrical distribution boards, switchgear panels, control panels, and industrial equipment. Also known as cartridge fuse clips, rewireable fuse clips, fuse carrier clips, copper fuse holders, fuse contact clips, fuse end caps, fuse connector clips, and fuse terminal clips, these components are an essential element of every fuse-based overcurrent protection circuit.

Copper is the preferred material for fuse clips due to its excellent electrical conductivity (approximately 100% IACS), high thermal conductivity for efficient heat dissipation from the fuse element, and resistance to oxidation when plated. Our copper fuse clips are pressed from high-purity electrolytic tough pitch copper (ETP Copper, CW004A / C11000) or phosphor bronze (CW451K) for spring-action clip variants, ensuring consistent contact force and long service life.

Types of Copper Fuse Clips We Manufacture

Flat Copper Fuse Clips (Blade Type): Simple flat pressed clips with a U-shaped or V-shaped contact profile that grips the cylindrical end cap of the cartridge fuse. The most commonly used type for D02, D03, 22×58 mm, 14×51 mm, and 10×38 mm fuse sizes.

Spring Copper Fuse Clips: Pressed from phosphor bronze or beryllium copper with an integral spring action to provide consistent clamping force on the fuse end caps. These maintain contact force over thousands of insertion cycles, critical in applications subject to vibration.

Copper Fuse Clamps (Screw Terminal Type): Clamp-style assemblies where the fuse end cap is secured mechanically by a clamping screw. Used where the fuse must remain firmly in place under vibration or where high current ratings require maximum contact area.

NH Fuse Clips (High Rupturing Capacity): Larger, heavy-duty copper clamps for NH (Neozed High Breaking Capacity) fuses in the 000, 00, 0, 1, 2, 3, and 4 sizes used in main distribution switchgear.

BS 1361 / BS 88 Fuse Clips: Copper clips sized and shaped for British Standard cartridge fuses as used in consumer units and industrial distribution boards in the UK market.

Panel Mount Copper Fuse Clips: Clips with integrated fixing tabs or screw holes for direct mounting onto DIN rails, PCBs, or panel metalwork without requiring a separate fuse holder body.

Materials and Surface Finishes

Standard copper fuse clips are pressed from ETP Copper (CW004A / C11000) strip of 0.8 mm to 2.0 mm thickness depending on the current rating. For applications requiring spring function, phosphor bronze (CW451K / C51000) at 0.5 mm to 1.2 mm provides the required combination of conductivity and spring properties. Surface finishes available include: electro-tinned copper (most common for solderability and oxidation prevention), silver-plated copper (for high-temperature or high-current applications), nickel-plated copper, and natural copper (as pressed). Tin plating is typically 5–10 µm electrolytic or hot-dip. Silver plating is 5–15 µm over a nickel undercoat.

Dimensions and Current Ratings

Our copper fuse clips are manufactured for the following fuse cartridge dimensions: 5×20 mm (miniature), 6.3×32 mm, 10×38 mm (1/4″ × 1.5″ Midget), 14×51 mm, 22×58 mm (IEC standard), 27×60 mm, 38×90 mm, and custom sizes. Current ratings range from 1 A to 630 A depending on the clip design, material, and fuse size. Voltage ratings are 250 V AC and 400 V AC for standard types, and up to 690 V AC for heavy-duty NH fuse clamp versions.

Manufacturing and Quality Assurance

Copper fuse clips are manufactured on our high-speed progressive die stamping presses, delivering tight dimensional tolerances of ±0.05 mm on critical contact dimensions. Each production batch undergoes contact resistance testing, spring force measurement (for spring type clips), plating thickness verification using XRF (X-ray fluorescence) equipment, and salt spray testing per ASTM B117 for tinned variants. Our facility is ISO 9001 certified and we maintain full batch traceability from material certificate to finished product.

Applications

Copper fuse clips are used extensively in: low-voltage power distribution boards and panelboards, motor control centres (MCCs), industrial control panels, domestic consumer units, automotive fuse boxes and PDUs, electronic equipment internal fusing, UPS and battery systems, solar PV combiner boxes and DC distribution, marine distribution panels, and railway rolling stock electrical systems. Any application using cartridge fuses for overcurrent protection will require copper or copper alloy fuse clips as the primary contact and retention element.

Frequently Asked Questions (FAQ) – Copper Fuse Clips and Clamps

What is a copper fuse clip used for?

A copper fuse clip is used to hold a cartridge fuse securely in circuit, providing the electrical contact between the fuse end caps and the circuit conductors. It must maintain low contact resistance to minimise heat generation and consistent contact force to ensure the fuse operates correctly under fault conditions.

What is the difference between a fuse clip and a fuse clamp?

A fuse clip typically uses spring force or a formed channel to grip the fuse end cap, whereas a fuse clamp uses a mechanical screw or lever to clamp the fuse firmly in place. Clamps are used for larger, higher-current fuses where spring clips alone cannot provide sufficient contact force.

What copper alloy do you use for fuse clips?

We use ETP Copper (CW004A / C11000) for standard fuse clips and Phosphor Bronze (CW451K / C51000) for spring-action clips requiring high elastic recovery. Silver-plated copper clips use C11000 base material with silver plating for applications requiring maximum conductivity and oxidation resistance.

Can copper fuse clips be tinned for soldering?

Yes, our standard copper fuse clips are available electro-tinned to a minimum 5 µm thickness, making them suitable for wave soldering or hand soldering onto PCBs or bus bars. Solder-dipped (hot-dip tin) versions with heavier coating are also available.

Do you manufacture copper fuse clips for NH/HRC fuses?

Yes, we manufacture heavy-duty copper clamps for NH fuses (also called HRC or High Rupturing Capacity fuses) in sizes 000, 00, 0, 1, 2, and 3, rated up to 630 A at 400 V AC. These are used in main distribution switchgear and industrial power distribution equipment.

What is the minimum order quantity for copper fuse clips?

Standard minimum order is 1,000 pieces per size and finish. For custom sizes or new tooling, we require a minimum of 5,000 pieces amortised over the first order. Sample quantities of 50–100 pieces are available for product qualification testing.

Do you export copper fuse clips?

Yes, we export copper fuse clips globally, primarily to the UK, Germany, France, UAE, South Africa, Australia, and Southeast Asian markets. We provide full export documentation including certificate of conformity, test reports, and material certificates.

Can you produce custom fuse clips to our drawing?

Yes, we manufacture custom copper fuse clips to customer-supplied drawings or samples. Our in-house tool room designs and fabricates progressive dies for new profiles. Development lead times are typically 3–5 weeks depending on complexity.
