What is the primary function of a circuit protector?

The primary function of a circuit protector is to prevent electrical overload. Circuit protectors, such as fuses and circuit breakers, are designed to safeguard electrical circuits by interrupting the flow of current when it exceeds a certain threshold. This overload can occur due to various reasons, including short circuits or excessive load on the circuit. By cutting off the power supply in such situations, circuit protectors help prevent overheating, damage to appliances, and even fire hazards. This protective mechanism ensures that electrical systems operate within safe parameters, thus maintaining both safety and functionality in various applications.
