LT-40GX T2 Class Ultra-Low Residual Voltage Lightning Arrester for Precision equipment

The surge protection device belongs to T2 AC power surge protector,which is installed between the power supply network and the equipment to drain,suppress and reduce the overcurrent and overvoltage caused by induced lightning strikes or the power grid system,so as to reducethe harm to the electrical equipment.This product belongs to the ultra-low residual voltage SPD,and the protection effect after multiple similar protectors are combined is not as good as one ultra-low residual voltage SPD.
