The purpose of fuse is surely for protection of circuit and equipment's as well as the person but to know what is the use of fuse lets check what is fuse, A fuse is nothing more than a short length of wire designed to melt and separate in the event of excessive current. There are many kinds of fuse some for house hold some for industrial purposes such as HRC(High Rupture Capacity) fuse and fuses also vary according to voltage grades. Now lets come to the main question what is the use of fuse, it breaks the circuit when excess amount of current passes through it for a given amount of time, it does not give protection from over current or short circuit for which we use circuit breaker which breaks the circuit when current exceeds the set value, so what does fuse is used for? it is used for protection of equipment and circuit from OVERLOAD. Lets take an example if the fuse is of 32 Amps for an equipment having rated current of 27 amps and 30 amps is flowing through it for a long time the fuse will melt and it will protect the equipment from overload even if there is no short circuit. Hope you find this answer useful.

Fuse is a protective device that is designed to protect an electrical power system from the harmful effects of the over current. Fuse are sacrificial in that they are generally good for one time use and are destroyed in the process of operating.
