3P DC 1500V 20kA/40kA T2 SPD Surge Protective Device, Copper Plastic for Solar PV Lightning Protection, YST-D6

Product details

With a maximum discharge current of 40kA (nominal current In: 20kA), this SPD effectively diverts high-energy surge currents, protecting 1500V DC solar PV systems from lightning strikes and transient overvoltages.

Certified to EN/IEC 61643-31 standards, this T2 SPD delivers robust secondary lightning protection, ideal for installation at the combiner box and inverter side of high-voltage solar systems.

With a protection voltage (Up) of ≤ 4.8kV, it limits residual voltage to a safe level, preventing equipment damage and ensuring consistent performance even during severe surge events.

The 3-pole design (DC+/GND/DC-) provides comprehensive protection for both positive and negative DC lines, suitable for full bipolar 1500V solar system setups.

Features a green/red LED display (Green: Normal, Red: Fault) for at-a-glance monitoring of working conditions, simplifying maintenance and reducing downtime in solar power plants.

Built with high-quality copper internal parts for excellent electrical conductivity and low thermal resistance, ensuring long-term durability and reliable operation in harsh outdoor environments.

Compact IP20-rated housing with standard DIN rail installation allows for quick and easy integration into distribution boxes and combiner cabinets, saving valuable space in solar installations.
