Tinned Copper Fuse Wire is a type of electrical wire that is commonly used in fuses and circuit breakers. It is made from high-quality copper wire that is coated with a layer of tin to improve its conductivity and resistance to corrosion. Tinned Copper Fuse Wire is typically available in spools or coils of various lengths and gauges, which are suitable for different types of fuses and circuits. The wire is easy to work with and can be cut to the desired length to replace a blown fuse or repair a circuit.
