1、House Surge Protector: Prevent excessive shocks to the home grid, insulated terminal blocks, more reliable, safer, quick response time and high carrying capacity. 2、Indicator Window: Working status indication window, can effectively respond to the working status, green indicates normal, red indicates fault. 3、PC Shell: The surge protector's PC housing is fire and corrosion resistant, and its plug in design supports hot wire operation for ease of use. 4、Quick Response: When a surge overvoltage occurs in the system, the protector immediately turns on quickly within nanoseconds and directs the surge overvoltage to earth. 5、Easy Installation: The surge protector is rail mounted and very simple, so you can easily complete the installation steps. Item Type: House Surge Protective Device Material: PC Color: White Maximum Discharge Current (Imax): 150KA Nominal Discharge Current (In): 100KA Protection Level (up): 2.7KV Maximum Continuous Operating Voltage (uc): 385V Protection Level: IP20 Response Time: ≤25ns Maximum Wire Diameter: 35 hard wire or multi-strand wire (mm²) Recommended Wire Connections: 4-25 (mm²) Installation: 35mm electrical rail mounting Ambient Temperature: -40℃-80℃ Main Structure and Working Principle: Under normal circumstances, the protector is in a high resistance state, when the power grid due to lightning strikes or other reasons out of the reason surge overvoltage, the protector will be immediately in the nanosecond time quickly on, the voltage overvoltage into the earth, thus protecting the power equipment on the grid. When the surge voltage through the protector, and disappears after the protector revert to a high resistance state, so as not to affect the normal operation of the grid. 1 x House Surge Protective Device
