DDB-2J type power lightning arresterDetailed product description：

Product Usage
The DDB-2J power lightning arrester is suitable for use in 220/380V single-phase AC power grids with a power supply capacity of less than 10kVA, for lightning protection against 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;
Full mode protection design;
Multi channel interception and current sharing technology;
Automatic fault detachment (lightning protection unit);
Lightning strike count.
