FAQs
The PVS400A-3L-15 is designed for immediate compatibility with the SD3L-S-PV XL fuse base. Begin by ensuring base suitability for a 3L PV fuse, mount the base in a compliant PV protection cabinet, and insert the 3L fuse with top indicator oriented for visible status. Connect to the DC positive and negative busbars per your DC string layout, verify the indicator shows normal operation, and perform a functional test with the inverter in a controlled environment before full- load operation.
The 400 A rating indicates the maximum continuous current the fuse can carry in a PV string without tripping. The 1500 V rating confirms suitability for mid-to-large DC PV strings common in utility-scale and commercial installations. The 100 kAIC interrupt rating represents the maximum fault current the fuse can interrupt safely, providing protection against severe short circuits typical in long PV runs.
Yes. The PVS400A-3L-15 is specifically designed for 1500 V DC photovoltaic systems and inverters. Its Class gPV designation, UL Listed status, and CE RoHS compliance support safe operations in both utility-scale and commercial rooftop applications, while its 3L size and top-indicator feature streamline integration in standard PV protection cabinets.
Key certifications for this fuse include UL Listed and CE marking with RoHS compliance, ensuring acceptance in North American and European markets. IEC 60269 compatibility confirms alignment with standard fuse requirements, while the PV-specific Class gPV rating provides assurance for DC protection in PV arrays and inverters.
The top indicator enables rapid visual status checks, reducing maintenance time and lowering the risk of undetected faults. Its robust 400 A/1500 V ratings and 100 kAIC interrupt capability mitigate costly downtime from faults. Compatibility with the SD3L-S-PV XL base speeds up installation and upgrades, delivering faster project timelines and long-term reliability benefits for PV protection programs.
