Lightning Surge Protector SPD DK-380AC50G
Brief Introduction
Dikai DK-380AC50G Voltage Switching Type high engery modular SPD is designed according to IED standard. The dush current of each signal module can be up to 50kA(10/μS). This products is especially suitable for application in the A grade Lightning Protetion in high risk area of lightning strike. And it could be installed in 380V AC power system.
This model designed in modular with excellent airtight property. It is with 35mm electrical lead rail, which make it easy for installation. It also has the advantage of low residual voltage, quick response, high discharge capability, long life, completed variety, easy maintainance and so on. It could also be designed according to buyers’ parameters.
