Surge Protective Device
The surge protective device is suitable for 50Hz, 380V TT, IT, TN-S, TN-C-S power supply system, providing the protection for power networks against lightning impulse. When the surge protector fails in breakdown for over-heat and over-current, the failure release will make the electric device separate from the power system and give a indication signal. The module of the protector can be replaced with voltage on. The product is manufactured according to IEC 61643-1 standard.
