Fuse vs. Circuit Breaker: Difference and Comparison
Edited by Muazma Batool — By Muneeza Rehman — Published on April 17, 2024
Fuses provide overcurrent protection by melting an internal conductor, permanently breaking the circuit; circuit breakers trip to interrupt current flow, but can be reset and reused.
Difference Between Fuse and Circuit Breaker
Fuses and circuit breakers both serve to protect electrical circuits from overload or short circuits, but they operate differently. A fuse contains a metal wire or filament that melts when too much current flows through it, effectively breaking the circuit. This action is irreversible, meaning once a fuse blows, it must be replaced. Circuit breakers, on the other hand, are designed to trip a switch when they detect an overload or short circuit, automatically or manually interrupting the flow of electricity. Unlike fuses, circuit breakers do not need to be replaced after they trip; they can simply be reset once the issue has been resolved, making them more convenient for repeated use.

The choice between using a fuse or a circuit breaker often depends on the specific needs of the electrical system. Fuses are typically less expensive and react more quickly to overcurrent, providing a higher level of protection for sensitive electronic equipment. However, their one-time use and the need for replacement can be seen as a disadvantage.

Circuit breakers offer a more user-friendly solution, with the ability to easily reset the system after a trip. This convenience makes them a preferred choice for most residential and commercial buildings. However, they are generally more expensive than fuses and may not react as quickly to overcurrent situations.

In terms of installation and maintenance, fuses are simpler to install but require more maintenance due to the need for replacements. Circuit breakers, while more complex and costly to install, require less maintenance over their lifespan, as they do not need to be replaced after tripping.
