How is Power Strip's overload protection implemented?

Power Strips (power sockets) are an important component designed to protect the safety of electronic equipment and users. Its overload protection function is one of the key features that ensures timely interruption of power supply to prevent fire and equipment damage when the load of connected equipment exceeds safe levels.

Overload protection is provided by built-in electronic protection devices or fuses. An electronic protection device is an intelligent circuit capable of monitoring the current load of connected equipment in real time. Once it is detected that the current exceeds the set safety threshold, the electronic protection device will immediately cut off the power supply to avoid overload conditions. This protection device usually resets automatically and automatically restores power supply after the overload problem is resolved, without the need for manual operation by the user.

Another common form of overload protection is a fuse. A fuse is a simple yet effective safety device that will blow when the load on a connected device exceeds the fuse's rating, cutting off the circuit and preventing current from continuing to flow, thereby protecting the outlet and connected devices from damage. After the overload protection is triggered, the user needs to manually replace the fuse to restore power supply.

The Power Strip is also equipped with an electronic reset button. When the overload protection is triggered, these buttons automatically cut off the power supply and automatically reset after a period of time to restore the power supply. This design allows users to resume normal use without manual intervention and only need to wait for a period of time.
