We warmly welcome you to wholesale dc spd 20/40ka surge protective device for sale here from our factory. All customized products are with high quality and competitive price.
Product Introduction
The KNS6A series DC power surge protector, a DC SPD 20/40KA Surge Protective Device, is suitable for lightning protection of solar photovoltaic power generation systems or other DC power systems.
As a reliable DC SPD 20/40KA Surge Protective Device, it can be used normally in high-altitude areas (5000m). This DC SPD 20/40KA Surge Protective Device helps protect DC power systems from lightning strikes or overvoltage damage. Therefore, the KNS6A series is an ideal DC SPD 20/40KA Surge Protective Device for such applications.
Features
· Extra-wide electrical clearance and creepage distance, ultra-high withstand voltage rating, meeting the requirements for use in high-altitude areas.
· Strong lightning current discharge capability, suitable for solar power generation systems.
· Modular, separable structure, convenient operation and maintenance.
· Equipped with remote signaling contacts for remote monitoring.
· Dual thermal trip devices, temperature-controlled circuit breaking technology.
· Visual alarm window color indicates protection operating status: green (normal) and red (fault).
· High operating voltage, high current carrying capacity, high safety, and high stability.9. Ambient environment freeing from explosive danger and air or dust which may cause corrosion of metal or weakness of insulation.
