Fuse wire is a safety device which is used to limit the current in an electrical circuit.
Fuse wire is used as a safety wire which is connected in series with the live wire. The fuse wire melts and breaks the electric circuit when there is a supply of large current or malfunctioning in the electric connections.
The advantage of using a fuse wire is that it protects the circuit and other electrical appliances by stopping the flow of excess current.
Following are the characteristics of fuse wire:
- It has a high resistivity
- It has a low melting point
