Eaton PVS315A-3L-15 Photovoltaic Fuses - 100 kAIC
Part Number: PVS315A-3L-15
Quick Summary
Eaton Bussmann series photovoltaic fuses protect solar arrays by safely interrupting overcurrent in high‑voltage DC PV circuits. Engineers and procurement teams often struggle to select devices that resist arc energy, minimize downtime, and withstand outdoor exposure. These fuses are CE marked, RoHS compliant, and UL listed, with IEC 60269 alignment for global compliance. With a 315 A rating at 1500 V in a 3L package and a top indicator, they offer robust protection plus easy field checks. Designed for PV strings and inverter protection, they help reduce maintenance costs and improve uptime. The PVS315A-3L-15 is compatible with SD3L-S-PV XL bases, supporting simple retrofit and scalable solar deployments.

FAQs
The PVS315A-3L-15 is designed to be compatible with the SD3L-S-PV XL fuse base. Ensure the base is mounted per enclosure guidelines, insert the 3L fuse, and verify a secure mechanical and electrical connection. Use the top indicator to confirm status during commissioning and routine maintenance. Follow the manufacturer’s torque recommendations for clean, repeatable connections.
It combines a 315 A current rating with a 1500 V voltage rating, plus a 100 kAIC interrupt rating for rapid fault clearance. This configuration is engineered for high‑voltage PV strings and inverters, delivering reliable protection while minimizing arc energy and insulation stress in large solar installations.
Yes. The device is UL Listed and designed in line with IEC 60269 standards, and it carries CE marking with RoHS compliance. This ensures global compliance for diverse markets and simplifies cross‑border PV projects.
Pre-arc I2T of 175000 indicates the fuse’s energy handling before arc initiation, supporting predictable arcing behavior and selective coordination with downstream protection. This reduces arc damage and improves system reliability in PV strings and inverter circuits.
By delivering robust overcurrent protection with fast fault clearing, the fuse minimizes downtime, protects costly PV assets, and lowers maintenance and replacement costs. Its compatibility with common fuse bases simplifies retrofits and upgrades, accelerating project deployment and total cost of ownership reductions.
