- A fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit.
- Fuses are widely used for the protection of electric motor circuits against small overloads and short circuits.
- The motor protection circuit will open the controlling contactor automatically, and the fuse will only operate for short-circuits or extreme overload.
Resistance:
The property of any conductor that opposes the flow of electric current through it is called resistance.
