PVS-3L Fuses data sheet
The 400 A, 1500 V rating provides robust protection for PV inverters and high-voltage arrays in utility-scale and commercial installations. This combination lowers the risk of damaging faults while enabling fast interruption to minimize downtime and component wear. With a 100 kAIC interrupt rating and 315000 A2T pre-arc capability, the fuse rapidly extinguishes faults before they propagate through conductors or modules. The business impact is safer installations, reduced fire risk, and improved regulatory confidence for PV project stakeholders. Physical compatibility with the SD3L-S-PV XL fuse base and the 3L fuse size simplifies installation and spares management. At 205 mm long, 82 mm high, and 75 mm wide, the device fits common PV protection enclosures without requiring custom cabinetry. Application scope includes photovoltiac systems and inverters, where reliable protection under high DC voltage is essential. The non-indicating fuse indicator avoids unnecessary maintenance signals, improving reliability in busy field deployments. Compliance with CE Marking and RoHS, along with UL Listed IEC 60269 certification, supports global procurement and regulatory adherence. This certification mix accelerates audits and simplifies supplier qualification for engineers and procurement teams. Watt losses of 71 W are typical for high-capacity PV fuses and should be accounted for in enclosure thermal management and airflow planning. The resulting heat, when correctly mounted in ventilated enclosures, remains manageable and does not compromise overall inverter efficiency. Installation and maintenance gains come from standardized dimensions and common base compatibility, reducing field complexity and downtime during replacement. This translates into lower labor costs and faster project commissioning for EPCs and operators. From a procurement perspective, the PVS400A-3L-U-15 delivers a proven protection solution backed by recognized certifications, offering predictable lead times and compatible spares across projects.
