Surge protectors are commonly used devices to limit lightning overvoltage and are commonly used in power supply systems with 220V/380V power supplies. Generally installed in the low-voltage main distribution cabinet of the building, it can protect the power supply equipment installed at the power incoming end of the power distribution system at the boundary of LPZ0 and LPZ1 of the building, and the withstand impulse voltage category is Class IV.
