Eaton SD3L-S-PV Photovoltaic Fuses - UL Listed

The 500 A, 1500 V DC rating ensures robust protection for large solar strings facing elevated DC fault currents. This capability translates into faster fault clearance with controlled arcing, reducing the risk of module damage and fire in harsh environments. Designed for the XL PV fuse base and 3L fuse links, it integrates seamlessly into existing protection schemes on industrial and commercial sites. In growing PV deployments, engineers benefit from a single family solution that scales across multiple plant configurations, improving consistency and purchasing efficiency. UL Listed certification, CE Marking, and RoHS compliance provide regulatory assurance and simplify supplier audits across North America and Europe. The inclusion of these declarations in the product data helps procurement teams meet internal safety standards without chasing multiple approvals. In practice, this reduces time-to-approval and lowers risk of non-compliance penalties during site upgrades. The robust certification package also supports traceability and service provider confidence in replacement parts. The physical footprint—22 mm depth, 22 mm height, and 58 mm width—fits common XL base enclosures without enclosure redesign. At 242 g, it offers a stable mechanical profile, easing mounting and cable routing in congested electrical rooms. Compatibility with standard 3L fuse links streamlines field retrofits, minimizing downtime during upgrades. The compact form factor also simplifies stocking and logistics for installers supporting nationwide rollouts. In growing PV deployments, SD3L-S-PV supports scalable protection strategies across multiple sites with consistent performance. Engineers can expect reduced downtime from overcurrent events, lower maintenance costs, and improved asset longevity when integrated with comprehensive electrical protection schemes. This translates to a lower total cost of ownership and faster project ROI in solar installations. Extensible to field upgrades, extensive technical data, including datasheets and conformity declarations, supports precise engineering calculations and compliant documentation. Field technicians benefit from clear install instructions and compatibility notes for PV arrays up to 1500 V DC, ensuring safer, faster upgrades.
