FAQs
The PV-400A-3L is designed for use with the SD3L-S-PV XL fuse base. This compatibility ensures blade-type connections fit cleanly without bolt holes, enabling a secure, tool-friendly installation in PV arrays, inverters, or disconnects while maintaining fast fault response.
Key specs include a 400 A amperage rating, 1000 Vdc voltage rating, 50 kAIC interrupt rating, and class gPV designation. It’s a high-speed PV-3L fuse with a top status indicator, designed to minimize arc duration and protect DC photovoltaic circuits effectively.
Yes. The PV-400A-3L is purpose-built for photovoltaic systems, including PV arrays, inverters, and array combiners. Its 1000 Vdc rating supports large commercial installations, while its fast-acting design limits fault energy, reducing the risk of collateral damage.
The fuse is certified to IEC 60269, UL Listed, and CSA Certified, with RoHS compliance and CE marking. These certifications verify safety, reliability, and environmental compliance for regulated installations in global markets.
The top fuse status indicator speeds fault detection and replacement, minimizing downtime. The high interrupt rating and robust construction improve system uptime, while standardization with existing bases reduces spare parts inventory and maintenance costs across multiple PV projects.
