The purpose of fuses, broadly speaking, is to protect the electrical circuits and cables in your equipment from damage when excessive electrical current (called overloading or overcurrent) is present in the circuit. Fuses are designed as an effective safety device protecting against an overflow of electrical current.
How do fuses work?
If too much current flows through a device, the fuse is designed to blow which effectively stops the flow of electricity through the circuit. Imagine the fuse as a bridge, and so once the fuse blows, the bridge no longer exists, thereby stopping the flow of electricity in the circuit thereby protecting wiring and components in the circuit.
What are the types of fuses?
There are many different types of fuses, all of which are designed to protect cable or equipment operating in either AC voltage or DC voltage circuits.
AC fuses are designed to protect circuits using alternating current and are often classified as either a high voltage fuse (HV) or low voltage fuse (LV).
LV Fuses: Low voltage fuses commonly include varieties such as cartridge, blade, bolted, bottle and knife blade fuses. Many of these fuses feature an indicator or striker to alert a blown fuse.
HV Fuses: Typically, HV fuses are used to protect transformers, and are designed for operating in voltages of 1500V and higher. High voltage fuses often feature a ferrule or cartridge style body such as a Cartridge type HV HRC Fuse. Some fuses are designed to operate in air whilst others in an oil filled environment such as a Liquid type HV HRC Fuse
How do you replace a blown fuse?
Once a fuse has blown, it must be replaced. Fortunately, fuses are much easier, and cheaper to replace compared with other components in the circuit or the device itself. If there was no fuse present in your device, a surge in current could damage components and/or wiring in your device. In addition, there could be a chance of personal injury or fire.
