What term is used for devices that protect electrical components from exceeding current ratings?

Voltage regulators
Fuses
Over-current devices
Surge protectors

The correct answer is: Over-current devices

The term used for devices that protect electrical components from exceeding current ratings is over-current devices. These devices are specifically designed to interrupt the flow of electricity when the current exceeds a predetermined limit, thus preventing damage to circuits and components. Over-current devices include fuses and circuit breakers, which are crucial to ensuring safety in electrical installations. By sensing the increase in current, they act as a safeguard, disconnecting the electrical supply before any components can become damaged from excess current flow. While fuses are indeed a type of over-current device, the term "over-current devices" encompasses a broader category, including both fuses and circuit breakers. This makes it the most inclusive and accurate choice when discussing devices that provide this specific type of protection.
