Scope Series Surge Protector (Power lightning protection module) is mainly applied to three-phase power system, the operating frequency of 50Hz / 60Hz, 400V and below the TT, IT, TN-S, TN-CS and other standard, low-frequency power supply system The equipotential bonding on the grid due to lightning or surge overvoltage effective protection. 2. Normal operating conditions Ambient temperature: -40 ℃ ~ + 70 ℃; Relative humidity: ≤95%; Altitude: ≤3 km; Do not install explosive medium; Do not install metal corrosion and damage the insulation gas and dust. 3. Under the main structure and working principle of protection normally in a high impedance state, when the power grid or other reasons overvoltage surge protector will be immediately turned over quickly nanosecond time, the surge voltage into the earth, and thus protect the safety of the power grid of electrical equipment. Set on the protection module failure from the device, when protection from overheating, breakdown failure, failure from the device can automatically be removed from the power line, while giving an indication signal. When the protection is working properly, the indicator shows green, red back from failure. Lightning Lightning Lightning Protection Module Module Module Module Lightning
