How is fuse made

This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily. If the current going through the fuse is too great, the wire heats up until it melts and breaks the circuit.

Fuses in plugs are made in standard ratings. The most common are 3 A, 5 A and 13 A. One may also ask, what are the 3 types of fuses? The low voltage fuses are divided into five types such as rewirable, cartridge, drop out, striker and switch fuses. Image Source. Rewirable Fuses. Cartridge type Fuses. D-type Cartridge Fuse. Link Type Fuse. Blade and Bolted type Fuses. Fuses are sacrificial devices used to protect much more expensive electrical components from the damaging effects of overcurrent.

Fuses consist of a low-resistance metal or wire that is used to close a circuit. The fuse is the current interrupting devices which break or open the circuit by fusing the element and thus remove the faulty device from the main supply circuit.

The fuses are mainly classified into two types , depends on the input supply voltages they are the AC fuses and the DC fuses. The fuse element is made of zinc, copper, silver, aluminum, or alloys to provide stable and predictable characteristics. The fuse ideally would carry its rated current indefinitely, and melt quickly on a small excess. Is Nichrome used in fuse? Why is nichrome not used in making a fuse? The key benefit of nichrome is that it has a high melting temperature and retains strength when red-hot, to function as an electrical heating element.

Nichrome is also quite a bit more expensive than most other conductive materials. Which metal is used in fuse? The material used for making fuse element has a low melting point such as tin, lead, or zinc.

A low melting point is, however, available with a high specific resistance metal shown in the table below. When a current higher than the rating of the fuse flows through it, the fuse wire gets heated and melts. This breaks the circuit and protects the appliances from getting damaged.

An ideal fuse must have the following properties. The appliances which work on large current have fuse of higher current ratings. The appliances which work on small current have fuse of smaller current ratings. On signing up you are confirming that you have read and agree to Terms of Service.
