Eaton PVS355A-3L-U-15 Photovoltaic Fuses - UL Listed
Part Number: PVS355A-3L-U-15
Quick Summary
Eaton Bussmann series photovoltaic fuses protect PV inverters and solar power systems from overcurrent events. Designers often struggle with selecting high-voltage fuses that fit 1500 V DC arrays while minimizing nuisance trips. These devices carry CE marking, RoHS compliance, and UL Listing with IEC 60269 compatibility, ensuring global acceptance and regulatory alignment. Beyond protection, they enable reliable, scalable PV installations by matching fuse size to system current and using a 3L form factor. The result is lower commissioning risk and predictable maintenance costs, with compatibility to standard fuse bases, which helps shorten installation time and reduce total cost of ownership for solar projects.

FAQs
The PVS355A-3L-U-15 is designed for direct replacement in systems using the SD3L-S-PV XL fuse base. Begin by disconnecting power, confirm DC Bus isolation, and align the fuse base with the PV string. Insert the 3L fuse ensuring proper seating, then re-energize and verify operation via system monitoring. Always follow manufacturer installation guidelines for PV protection components.
This fuse provides 355 A current rating and a 1500 V DC rating, with a 100 kAIC interrupt rating and Class gPV designation. It also features a Pre-arc I2T value of 250000, and watt losses of 59 W. These specs ensure reliable protection for high-energy PV strings while enabling safe, compliant shutdown during faults.
Yes. The PVS355A-3L-U-15 is purpose-built for 1500 V DC PV arrays and utility-scale inverter protection. Its 355 A rating aligns with common inverter outputs, while the high interrupt capability helps isolate faults quickly, reducing risk to modules and wiring in large sites.
The device is CE marked and RoHS compliant, and UL Listed with IEC 60269 compatibility. These certifications support global deployment, regulatory approval, and supplier qualification in diverse markets, ensuring compatibility with international electrical protection standards.
The non-indicating design lowers maintenance labor by reducing on-site checks, while the 3L form factor and SD3L-S-PV XL compatibility accelerate installation. Combined with high reliability and robust fault isolation (100 kAIC), this yields lower downtime, shorter project timelines, and improved total cost of ownership for PV systems.
