Eaton PVS400A-3L-BU-15 Photovoltaic Fuses - UL Listed
Part Number: PVS400A-3L-BU-15
Quick Summary
Eaton Bussmann series photovoltaic fuses protect solar power systems by interrupting faults in PV arrays. In practice, choosing the right fuse for 1500 V DC PV strings can be a challenge, risking costly downtime and fire hazards when protection isn’t fast or scalable. These devices are CE marked, RoHS compliant, and UL listed, with IEC 60269 certification and a 100 kAIC interrupt rating that support safe, long-term operation in utility-scale and commercial PV installations. By aligning with a 3L fuse size and compatible blade-bolt holders, you gain installation simplicity and consistency across inverters and string combiners, while maintaining standards compliance and reducing warranty concerns.
