1. House 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 protector's PC housing is fire and resistant, and its plug in design supports hot wire operation for ease of use. 4. Quick Response: When a overvoltage occurs in the system, the protector immediately turns on quickly within nanoseconds and directs the overvoltage to earth. 5. Easy Installation: The protector is rail mounted and very simple, so you can easily complete the installation steps. Specification: Item Type: House Protective Device Material: PC Color: White Maximum Discharge Current (Imax): 150KA Nominal Discharge Current (In): 100KA Protection (up): 2.7KV Maximum Continuous Operating Voltage (uc): 385V Protection : 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 strikes or other reasons out of the reason 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 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. packing list: 1 x House Protective DeviceEasy Installation: The protector is rail mounted and very simple, so you can easily complete the installation steps.
