Features Rapid Surge Protection: Activates in nanoseconds to divert overvoltage safely to the ground, safeguarding your home’s electrical equipment from damage Enhanced Reliability: Features insulated wiring terminals for a robust and safe connection, ensuring quick response and preventing excessive impact on your power grid Clear Fault Indication: Equipped with a visual indication window, easily monitor device status—green signals normal while red alerts for maintenance needs Features: 1、Main Function: Using this device to protect your house electrical equipment, which will turn on quickly within nanoseconds when there is a surge overvoltage, and introduce the surge overvoltage into ground. 2、High Performance: Adopt insulation wiring terminal, more reliable and safe, with quick response speed and strong carrying capacity, prevent household power grid from excessive impact. 3、Fault Indication: Designed with indication window, which effectively reflect the working status of the device, green color means normal, red color means fault, convenient for timely maintenance. 4、High Safety: This surge protector is fire and resistance, supports hot line and is easy to use. 5、Rail Installation: This surge protector is modular designed, supports 35mm electrical guide rail installation, easy to mount. Specification: Item Type: Surge Protective Device Material: PC Color: White Maximum Discharge Current (Imaximum): 80KA Nominal Discharge Current (In): 40KA Protection Level (Up): 2.2KV Protection Grade: IP20 Response Time: ≤ 25ns Maximum Wire Diameter: 35 hard wire or stranded wire (mm²） Recommended Connection: 4-25 (mm²） Installation Method: 35mm electrical guide rail installation Ambient Temperature: -40℃ to +80℃ Main Structure and Working Principle: In a three phase four wire system, protectors are connected between three phase wires and one neutral wire to ground. Under normal circumstances, the protector is in a high resistance state, when the power grid deals with surge overvoltage due to strike or other reasons, the protector will turn on quickly within nanoseconds, and introduces the voltage overvoltage into the ground, thus protecting the electrical equipment on power grid. When the surge voltage passes through the protector and disappears, the protector changes to a high resistance state again, so as not to affec Package List 1 x Surge Protective Device
