FAQs
PV-400ANH3-BL fuse-links mount in standard NH3 fault-protection assemblies with blade terminals and bolted holes. Ensure a solid backplane, proper lug kit, and clearances per the enclosure diagram. Observe the 150 mm depth and 71 mm width, and confirm DC conductor sizing for 1000 Vdc. The dual status indicator simplifies on-site fault confirmation.
The 400 A current rating with a 1000 Vdc limit supports protection of medium to large PV strings and DC buses, enabling rapid interruption at fault onset. This informs conductor sizing, insulation requirements, and protective coordination with upstream disconnects, reducing arc risk and helping meet design codes and safety standards.
Yes. PV-400ANH3-BL is engineered as NH3 fuse-links in gPV class devices and features bolted blade connections for reliable installation. It works with standard Eaton fuse holders and lugs, reducing field fabrication and wiring errors and supporting rooftop, carport, and utility-scale PV deployments.
The product carries IEC 60269, UL Listed, CSA Certified, and CE compliance. These certifications align with international protection standards, ease equipment qualification and safety audits, and help streamline multi-region procurement and commissioning for utility-scale solar projects.
Fast fault clearance minimizes downtime and potential module or inverter damage, reducing repair costs and extending system life. The dual indicator and durable bolted connections simplify preventive checks, while standardized NH3/gPV compatibility reduces spare-part diversity, delivering lower total cost of ownership over the project lifetime.
