Feature: 1. Main Application: This surge protector is mainly used to defend electrical systems and appliances from transient lightning and surge loads. 2. Visual Window: Green is normal, red is fault. This protector possesses visual alarm window, which can effectively show real time working conditions for you. 3. PC Material: The shell of the surge protector is made of PC material, which is flame retardant and corrosion resistant, it can effectively defend the protector. 4. Easy Using: This surge protector adopts plug in design, supports hotline operation, which is easy to use. And insulated terminal blocks are adopted for more reliable and safer performance. 5. Easy Installation: Adopts standard rail installation, the easy installation can be quickly completed in few steps. Specification: Item Type: Surge Protector Color: White Material: PC Maximum Discharge Current (Imaximum): 200KA Nominal Discharge Current (In): 100KA Protection Level (up): 3.0KV Protection Grade: IP20 Response Time: Less Than or Equal to 25ns Maximum Wire Diameter: 35 Hard Wire or Stranded Wire (mm ²) Recommended Connection: 4 to 25 (mm ²) Installation Method: Approx. 35mm / 1.38in Electrical Guide Rail Installation Ambient Temperature: - 40 ? to +80 ? Main Structure and Working Principle: In three phase four wire system, three phase lines and one neutral line are connected to the ground with protectors. Under normal conditions, the protector is in the state of high resistance. When the power grid suffers from surge overvoltage due to lightning stroke or other reasons, the protector will immediately be turned on within nanoseconds, introducing the voltage overvoltage to the ground, thus protecting the electrical equipment on the power grid. When the surge voltage passes through the protector and disappears, the protector will change to a high resistance sta
