Question

What type of electric fuse is used in electrical appliances like car stereos? Explain with the help of a labelled diagram.

Answer 1

To answer the given question, we will first begin by learning about the Cartridge fuse, which is used in car stereos, and then we will gain a better understanding of the concept by looking at its labelled diagram.

Complete answer:
Cartridge fuses are a type of fast safety device used in electrical systems to protect cables, power lines, and equipment from overloads and short circuits. A cartridge fuse's primary function is to protect systems and human life. Ceramic, porcelain, or glass is used to make cartridge fuses.
It is made up of a glass tube with a thin fuse wire sealed inside. At each end of the glass tube, there are two metal caps. Furthermore, the fuse's two ends are connected to the metal caps. These metal caps are used to connect the fuse to the circuit in a suitable bracket.

Additional Information:
Most cartridge fuses are rated for circuits ranging from $250{\text{ }}volts$ to $600{\text{ }}volts$ , depending on the fuse class, and for varying amperages up to $600{\text{ }}amps$ , again depending on the fuse. There are some exceptions.

Note:
It should be noted that cartridge fuses can be fast acting or time delayed, depending on the fuse class and series. Bussmann by Eaton, Littelfuse, and Mersen are three of the world's largest manufacturers of cartridge fuses.
