Product Overview:
The NH3 XL 1500V DC gPV fuse is a safety protection solution specifically designed for photovoltaic installations. It can be used in sub‑array, array, or inverter DC inputs of solar power systems. The NH XL series covers NH0, NH1 XL, NH2 XL, and NH3 XL fuse links with rated currents ranging from 40A to 630A. These fuses are rated for 1500V DC and provide overload and short‑circuit protection, conforming to the gPV class as per IEC 60269 and GB/T 13539.6 standards. The NH3 XL is constructed with a ceramic body that withstands high internal pressure and thermal shock.
Applications:
Ideal for high‑current PV DC combiner boxes, inverter DC inputs, PV arrays, sub‑arrays, and battery energy storage systems (BESS), where 1500V DC systems demand reliable protection for high current circuits. Suitable for utility‑scale solar power plants and large commercial PV installations.
Key Features:
- Current rating range: 63、65、70、75、80、90、100、110、125、160、200、250、300、315、350、400
- Rated voltage: 1500V DC
- Breaking capacity: 50kA
- Compliant with standards: IEC 60269-6 (gPV), GB/T 13539.6
- Square body / blade type design (Size: NH3 XL) – offering maximum surface area for superior heat dissipation
- Ceramic body with silver‑plated copper contacts and pure silver melting elements
Quality Assurance:
Manufactured to rigorous specifications, ensuring fast and reliable interruption of fault currents under harsh DC conditions, protecting your high‑voltage PV system investment.
