DB-2C type power lightning arresterDetailed product description：

Product use: DB-2C power lightning arrester is suitable for 220/380V, power supply capacity less than 1000kVA three-phase AC power grid, to prevent lightning overvoltage, electromagnetic interference, and high-order harmonics. Especially in areas where lightning protection zoning is difficult and it is not easy to implement multi-level protection for precision equipment.  
Industries of use: telecommunications industry, broadcasting industry, petrochemical industry, transportation and highway industry, financial industry, and government agencies at all levels.
Product features: Large flow capacity (8/20 μ S 100kA);
Residual voltage (<600V);
Prevent high-frequency electromagnetic waves and electromagnetic interference;  
Improve power factor and enhance the load capacity of the power grid;  
Seven mode protection design;  
Multi channel interception and current sharing technology;  
Automatic fault disengagement (lightning protection module);  
Deterioration indication, damage sound and light alarm;
Clock and calendar display;
Power grid voltage monitoring;
Record of lightning strike time and frequency;
RS485 or RS232 communication interface.
