What is the use of fuses in electrical distribution?

Fuses play a critical role in electrical distribution systems by providing a safety mechanism that protects circuits from damage caused by overloads or fault conditions. When the current flowing through a circuit exceeds a certain threshold due to a fault or excessive load, the fuse will melt its internal element. This action effectively breaks the electrical connection and interrupts the flow of current, which helps prevent overheating, potential fire hazards, and damage to equipment or wiring.

By ensuring that only safe levels of current are allowed to flow, fuses help maintain the integrity of the electrical system and the safety of the environment. Their predictable response to overloads makes them essential components in residential, commercial, and industrial electrical installations. Therefore, the use of fuses in electrical distribution is fundamentally about protecting circuits and maintaining system safety.
