Are essential electrical safety devices with several key functions. They safeguard electrical circuits and appliances by automatically interrupting the flow of electricity when it exceeds safe limits, preventing overheating and potential fires. Circuit breakers are also effective in quickly disconnecting circuits in the event of short circuits or other electrical faults, ensuring the safety of both the electrical system and users. Their convenience lies in the ability to reset them after tripping, eliminating the need for replacements, unlike fuses. Furthermore, circuit breakers provide greater control and safety when isolating specific circuits for maintenance or repairs in homes and buildings.
