Selection Guide & Compliance

Choose the right DC fuse for strings, inverters, ESS and DC bus — compliant with global standards

How to pick a Kuangya DC fuse

For string protection and DIN-rail layouts, use our cylindrical gPV fuses (10×38 / 14×51 / 10×85 / 14×85 / 22×125) with matched holders. For high-current feeders, combiner boxes, central inverters and battery energy storage DC bus, choose the square-body H0–H3 & H1-XL/H3-XL series. Both 1000V and 1500V gPV options are optimized for low I²t, high breaking capacity and consistent arc-quenching in PV fault conditions.

  • Voltage & system: 1000V or 1500V PV/ESS; match array Voc and inverter DC input.
  • Current rating: size against Isc × safety factor; check cable ampacity and heat rise.
  • Time-current curve: gPV characteristic for string/array faults and back-feed protection.
  • Form factor: DIN-rail cylindrical vs. square-body (H0–H3 / XL) for high current circuits.
  • Installation: use certified holders, torque to spec, maintain creepage/clearance.

FAQ — Kuangya DC Fuse

Quick answers about gPV fuses, voltage classes, applications and compliance

What is the difference between a gPV fuse and a general DC fuse?
gPV fuses are engineered for photovoltaic fault profiles: low I²t, fast interruption, and high DC breaking capacity to extinguish arcs at 1000V / 1500V. They protect strings, combiner boxes, and inverter DC inputs more reliably than general-purpose DC fuses. Explore Cylindrical gPV models e Square-Body high-current series.
How do I choose between 1000V and 1500V fuses?
Base the choice on array Voc, temperature, string architecture, and expansion plans. Rooftop/commercial PV typically use 1000V; utility-scale PV and ESS often use 1500V for higher efficiency and capacity. If future upgrades are expected, select 1500V gPV. See Cylindrical e High-Current.
When should I use 10×38, 14×51, 10×85, 14×85, or 22×125 sizes?
Use 10×38 / 14×51 for small to mid currents in DIN-rail layouts; 10×85 / 14×85 for higher voltage/current and thermal margins; 22×125 or square-body for very high current feeders/ESS. Always pair with certified holders from the Cylindrical selector or the Square-Body range.
H0–H3 vs H1-XL/H3-XL — what’s the difference and where to use them?
H0–H3 are square-body gPV fuses for high-current PV/ESS circuits (central inverters, DC busbars). XL variants (H1-XL to H3-XL) deliver even higher current density (e.g., 400–630A and above) for utility-scale arrays and battery racks. Browse High-Current models.
Do I need to use a matching DC fuse holder/base?
Yes. Certified holders ensure creepage/clearance, low contact resistance, and controlled heat rise. Tighten to the specified torque and follow installation notes. Matching bases are listed in Cylindrical e High-Current sections.
How to replace a PV fuse safely?
Isolate and lock-out the DC source; verify zero energy; identify and fix the root cause; replace with the same voltage class, characteristic (gPV), and equal/higher breaking capacity; torque connections per datasheet; record the change. See schede tecniche and contact supporto ingegneristico if unsure.
How do fuses coordinate with DC breakers and SPD?
Use gPV fuses to limit let-through energy (I²t) and protect conductors/devices; coordinate breaker trip curves downstream to avoid nuisance tripping. Install SPD DC with proper upstream OCPD and follow wiring/earthing best practices. For isolating, see DC switch-disconnectors.
Which standards apply — IEC, UL, NEC?
Kuangya gPV fuses reference IEC 60269-6 e UL 248-19, and PV installations should comply with NEC 690 or local codes. Verify markings, voltage class, interrupt rating, and use certified holders. See our Selection & Compliance section for guidance.
Any quick sizing tips for PV/ESS circuits?
Consider array Isc with appropriate safety factor, ambient temperature, conductor ampacity, enclosure heating, and time-current curves. Select the gPV characteristic for PV back-feed faults and confirm the holder’s rating. For detailed curves, see technical datasheets.
What about lead time, OEM/ODM printing, and documentation?
Common 1000V/1500V ratings are in stock with fast dispatch; custom ratings/printing/packaging are available via OEM/ODM service. Download the full datasheet pack o contattateci for quotes and samples.
