28 Swg Tinned Copper Fuse Wire

Description

Technical Specifications

Based on industrial standards (including IS: 9926), a single strand of 28 SWG tinned copper wire typically provides:

• Approx. Fusing Current: ~18 Amps to 20 Amps. This is the current at which the wire will melt to protect the circuit.

• Safe Current Rating: 5 Amps to 8 Amps. It is most commonly used as the fusing element in 5A or 6A Kit-Kat style porcelain fuse carriers.

• Resistance at 20°C: Approximately 0.155 to 0.165 $\Omega/m$.

• Material: High-purity copper with a tin coating to prevent oxidation and ensure reliable conductivity in humid environments.

Common Applications

• Domestic Lighting: The standard choice for protecting 5A lighting circuits in homes.

• Internal Equipment Fuses: Used in older appliances or industrial control panels for low-load sub-circuits.

• Electronic Hobby Work: Popular for DIY projects where a precise, low-current fuse point is required.

Product Recommendations

You can find 28 SWG fuse wire from various industrial suppliers, usually in 100g rolls for home maintenance or 1kg reels for professional use.

The 28 SWG Tinned Copper Fuse Wire is a high-quality industrial option. It is designed for consistent performance in porcelain fuse bases and is typically available in 1kg reels.

For smaller repair tasks or keeping in a toolkit, the 28 SWG Tinned Copper Wire is a practical choice. The tinning makes it highly resistant to corrosion and very easy to solder if needed.

Installation Best Practices

• Clean Terminals: Always use a screwdriver to scrape away black carbon deposits from the brass terminals of the fuse holder before fitting new wire.

• Check the Load: Ensure the total wattage on the circuit doesn’t exceed 5 Amps (approx. 1150W at 230V). Overloading will cause “nuisance blowing.”

• Avoid Over-Tension: Do not pull the wire tight. Leave a tiny amount of slack so the wire can expand as it warms up without snapping mechanically.
