The SP series surge protective device is applied to the alternating current 50/60Hz, 220V/380V power system and provides protection from surge overvoltage of an electric system. Moreover, the protection module, detachable device (fuse), and fastened power and ground wires are organized into the all-in-one steel cabinet by way of convenient installation and stability. If the protective device is normal, the display becomes green. The display becomes red after operation (abnormal or after an accident).
