What is the main advantage of using circuit breakers over fuses?

The main advantage of using circuit breakers over fuses is that circuit breakers can be easily reset after tripping. When a circuit breaker detects an overload or short circuit, it automatically interrupts the electrical flow to prevent damage or fire. Once the issue is resolved, the breaker can be switched back on without the need for replacement, making the system more convenient and efficient.

In contrast, fuses must be replaced once they blow, which can lead to downtime and additional costs. This ability to simply reset circuit breakers enhances their usability, especially in environments where electrical loads fluctuate frequently. Consequently, they are favored in both residential and commercial applications for their practicality and ease of use.
