Eaton PV-3A10-T Photovoltaic Fuse - Class gPV

The PV-3A10-T operates at 1000 Vdc and 3 A, making it ideal for protecting modern PV strings from fault initiation to system shutdown. The fast response minimizes energy released during a fault, protecting module junction boxes and wiring and enabling quick isolation to keep downtime to a minimum. This combination supports utility-scale solar farms and commercial rooftop arrays by delivering reliable, consistent protection under varying irradiance and temperature conditions. With a 50 kAIC interrupt rating, the device offers a generous fault current margin for multi-string configurations and high-density PV layouts. This reduces the likelihood of downstream component damage during surge events and simplifies coordination with upstream protection devices. The fuse's non-indicating design keeps packaging simple and reduces maintenance checks in hard-to-reach field installations. Certified class standards alignment reinforces compliance across regions: Class gPV with IEC 60269-6 type A confirms suitability for PV systems. UL Listed, CSA Certified, and CE Marked statuses cover major markets, while RoHS compliance ensures restricted substances are avoided in module wiring. This broad certification mix supports procurement integrity and reduces engineering risk during design reviews. Designed for bolt-fixed installation, PV-3A10-T uses a compact 10 x 38 mm fuse body with a 62 mm depth profile and 25 mm height, occupying modest space in junction boxes and combiner units. The 1–3 ms time constant describes the fuse's fast operating characteristic, delivering precise coordination with downstream protection while keeping energy losses at about 1.3 W under normal load. The compatibility with CHPV Modular fuse holders simplifies stocking and spares planning for solar projects. Mechanical robustness is evident with bolt fixing and an 11.8 g weight, supporting reliable field replacement and reduced vibration risk in outdoor environments. The 3 A rating aligns with common string currents and bypass diode behavior, while the 1000 Vdc rating matches modern PV array voltages for safe operation across wide temperatures. The product's scope includes compliance documentation and printable data for fast field engineering and audits.
