What is a surge protector?

A surge protector, also known as a lightning arrester, is an electronic device that provides safety protection for various electronic devices, instruments, and communication lines. When a surge current or voltage spike suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and divert the current in a very short time, thereby preventing damage to other equipment in the circuit.

Surge protectors are suitable for AC 50/60Hz power supply systems with a rated voltage of 220V/380V. They protect against surges caused by indirect and direct lightning strikes or other transient overvoltages, and are suitable for surge protection requirements in residential, service industry, and industrial sectors.
