Eaton PV-3A10F Photovoltaic Fuse - Class gPV, UL Listed

Eaton PV-3A10F offers a 1000 Vdc operating capability, enabling protection across high-voltage PV strings and inverters with minimal voltage drop. This translates to improved system reliability and compliance with utility-grade PV protection standards, reducing downtime and extending equipment life in commercial rooftops and utility-scale installations. The 3 A current rating paired with a 50 kAIC interrupt capacity ensures fast, decisive fault clearing for high fault currents, minimizing arc energy and potential damage to solar wiring and modules. The 1–3 ms time constant delivers swift isolation during faults, boosting safety for technicians during maintenance and enabling safer hot-swap capabilities in PV combiner boxes. The compact 10x38 mm ferrule ends guarantee straightforward replacement and compatibility with CHPV modular fuse holders and HPV-DV inline holders, simplifying inventory and field service. Low watt losses at 0.8 W reduce heat buildup, improving overall system efficiency and enabling longer fuse life in dense PV installations. Compliance with RoHS and CE, along with UL Listed and IEC rated certifications, supports global deployment and regulatory proof-of-conformance, reducing procurement risk. The non-indicating PV-A10F design keeps upfront costs low while providing reliable protection for 10x38 mm fuse holders across multiple string configurations. Application-ready packaging (quantity 10) enables swift stocking for service teams and project-based deployments.
