LD-WD series T2 high current surge protective device SPD is designed in accordance with IEC and GB standards, and is used as a second-level power surge protection product for power supply systems. The module is installed with a standard 35mm rail. It has a high surge current discharge capacity and the maximum discharge current can reach 150kA (8/20μs). It is applied to the second-level surge protection of the power supply of equipment systems in areas with high risk of lightning strikes.
There is no follow current problem, and the leakage current is small. This series SPD surge protector is easy to install and can be used in single-phase/three-phase power supply lines with combinations of different quantities SPD.
Application Sites:
◆General power distribution panel in the building
◆Overhead input distribution box in the building
◆Outdoor power distribution cabinet/distribution box
