Which one is better fuse or circuit breaker ?

The choice between a fuse and a circuit breaker depends on various factors, and both have their advantages and disadvantages.

Fuses are simple devices that interrupt the electrical circuit when the current exceeds a certain limit. They are effective in protecting against overcurrent and short circuits. Fuses are relatively inexpensive and straightforward to install. However, when a fuse blows, it needs to be replaced, which can be inconvenient.

Circuit breakers, on the other hand, are reusable devices that automatically disconnect the circuit when an overcurrent or short circuit occurs. Unlike fuses, circuit breakers can be reset after tripping, eliminating the need for replacement. They are more convenient in the long run and are often considered more user-friendly.

In terms of responsiveness, circuit breakers typically have faster reaction times compared to fuses. They can trip quickly to prevent damage to electrical appliances and wiring. Circuit breakers also offer better protection against sustained overloads, as they can be designed to handle both short-term and long-term overcurrent conditions.

However, circuit breakers can be more expensive upfront and may be more complex to install. Additionally, in some cases, fuses might be more suitable for specific applications, such as in environments with high humidity or extreme temperatures.

In summary, the choice between a fuse and a circuit breaker depends on your specific needs, budget, and preferences. Both have their merits, and the decision should be based on factors like cost, convenience, and the type of protection required for the electrical system.
