Fuses

A fuse is an electrical safety device that is designed to protect an electrical circuit from damage caused by overcurrent. Fuses are commonly used in residential, commercial, and industrial electrical systems, and they are an important safety device that helps prevent electrical fires, equipment damage, and personal injury.

A fuse typically consists of a metal wire or filament that is enclosed in a fuse body, which is designed to protect the wire from damage. The fuse is connected in series with the electrical circuit, and when the current flowing through the circuit exceeds a preset level, the wire in the fuse will melt or blow, which opens the circuit and prevents further damage to the electrical system.

Fuses are available in a variety of types and sizes, and they can be classified based on their current rating, voltage rating, and speed of operation. Some common types of fuses include cartridge fuses, blade fuses, and plug fuses.

In addition to protecting electrical systems from overcurrent, fuses can also be used to protect electrical equipment and machinery from damage caused by short circuits or other types of electrical faults.
