What is the difference between a fuse and a circuit breaker?
In the electrical category, a fuse and a circuit breaker are both designed to protect electrical circuits from overloading or short circuits by interrupting the flow of electricity. However, there are key differences between the two:
- Fuse: A fuse is a thin wire that melts and breaks the circuit when excess current flows through it. Once a fuse is blown, it needs to be replaced. Fuses are typically cheaper but require manual replacement.
- Circuit Breaker: A circuit breaker is an automatic electrical switch that is designed to trip and break the circuit when excess current is detected. Circuit breakers can be reset after they trip, making them more convenient and cost-effective in the long run compared to fuses.
Ultimately, the choice between a fuse and a circuit breaker depends on factors such as cost, convenience, and the specific requirements of the electrical system.
