Eaton PVS355A-3L-B-15 Photovoltaic fuses - UL Listed
Part Number: PVS355A-3L-B-15
Quick Summary
Photovoltaic fuses protect solar inverters and PV arrays by fast DC interruption in high-voltage installations. Manufacturers often struggle to pick fuses that reliably handle 1500 V DC while minimizing nuisance trips across dynamic PV strings. The PVS355A-3L-B-15 carries CE Marked, RoHS Compliant, UL Listed and IEC 60269 alignment for reliable global compliance and traceability. It is designed for 355 A at 1500 V in a 3L package with a side indicator, giving clear status in crowded equipment racks. This combination reduces maintenance downtime, improves uptime, and provides predictable protection for critical PV assets, while enabling straightforward installation and compatibility with blade-style holders—supporting efficient, scalable solar protection strategies.

FAQs
The PVS355A-3L-B-15 is designed for blade with bolt hole holders. Ensure the enclosure supports a 3L PV fuse, then seat the device securely in the holder, connect the 1500 V DC PV string leads, and verify the side indicator shows a healthy status after commissioning. Follow manufacturer torque specs and ensure proper clearance for high‑voltage connections.
It features a 1500 V voltage rating, a 355 A amperage rating, and a 100 kAIC interrupt rating, all housed in a 3L form factor with a side indicator. The Class gPV designation, along with UL Listed and CE RoHS compliance, ensures compatibility with high‑voltage PV strings and inverter protections across global standards.
Yes. The device is CE Marked, RoHS Compliant, and UL Listed, with IEC 60269 alignment. This combination provides regulatory assurance for international projects and simplifies supplier qualification, procurement, and cross-border deployments.
The pre-arc (I2T) rating of 250000 indicates the energy the fuse can handle before arcing occurs, influencing fault current interrupt behavior and arc energy. A higher I2T generally correlates with better protection during surge and fault events, helping to minimize damage to PV components and adjacent equipment.
This fuse combines high current and voltage ratings with clear status indication and compatibility with common blade holders, reducing installation time and downtime. Its regulatory compliance reduces procurement risk, while the robust interrupt performance and 3L form factor support scalable, reliable protection for commercial and utility‑scale PV installations.
