What is the primary purpose of a circuit breaker?

The primary purpose of a circuit breaker is to protect electrical equipment and people from overload. Circuit breakers are designed to interrupt the flow of electricity when they detect a fault condition, such as an overload or short circuit. This interruption helps prevent overheating, fires, and damage to appliances and wiring, ensuring that the electrical system operates safely.

When the electrical current exceeds a preset limit, the circuit breaker trips, cutting off the electricity supply. This safety mechanism not only protects devices from potential damage but also reduces the risk of electrical hazards that could lead to injury or property damage. By serving as a crucial safety component within an electrical system, circuit breakers play an essential role in ensuring the overall safety and reliability of electrical installations.
