company news about Can a copper wire be used instead of a fuse after it blows?

Generally speaking, it is not possible, because the resistance of the copper wire is small, so the internal energy generated when the current passes is small, and the melting point of copper is relatively high. Without the function of the protection circuit, it is easy to cause the fuse to blow.

However, it can be used as a temporary emergency, and it must not be used for a long time. There will be a potential safety hazard of overloading, and it is easy to cause a short-circuit fire.

The reason why fuses use metals with low melting points such as lead and tin is that they can protect electrical equipment and electrical circuits. When the current load is too large, the circuit may be destroyed.

However, if a lead-tin fuse is used, its melting point is low, and when the current is too large, it will be blown to protect the electrical appliance. The melting point of copper wire is much higher than that of lead and tin, and it will not fuse when the current is large, which will damage electrical appliances.

If you can't find it temporarily, you can use copper wire to replace it temporarily, but you should replace it as soon as you find it. Therefore, fuse selection is very important.
