What is described as a reusable safety switch that breaks the circuit when the current becomes too high?

Explanation:
When a device or wire carries more current than it safely can, a protective switch is designed to automatically break the circuit to prevent overheating or fire. This type of device is reusable because it can be reset after it trips, unlike a fuse that blows and must be replaced. A simple light switch doesn’t respond to overload on its own, and a residual current device trips for leakage rather than overcurrent. So the description points to a reusable safety switch, which is essentially a circuit breaker.
