What is the purpose of a circuit breaker?

A circuit breaker is designed primarily to protect electrical circuits from overloads and short circuits. Its main function is to automatically shut off the electrical flow when it detects a fault condition that could lead to excessive current. This mechanism helps prevent damage to wiring, reduces the risk of fire caused by overheating, and protects electrical appliances connected to the circuit.

When an overload occurs or a short circuit is detected, the circuit breaker interrupts the flow of electricity, minimizing the potential for hazards. This protection is vital for maintaining safety within electrical systems and ensuring that equipment continues to function efficiently without risk of damage from faulty conditions.

Understanding this function is crucial because it highlights the importance of circuit breakers in any electrical installation, as they serve as a safeguard against electrical faults that could lead to serious consequences.
