FAQs
The PV-350A-3L-BU-15 is designed for 1500 Vdc photovoltaic installations and is compatible with Eaton Bussmann PV fuse holders and standard DC solar string protections. Its Class gPV rating and bolted 3L form factor fit typical utility-scale and commercial PV configurations, delivering fast interrupting with a visible indicator for quick fault diagnosis.
With a high 350 A amperage rating and high-speed operation, the fuse rapidly opens on overcurrent events, minimizing arc damage and preventing backfeed across strings. The built-in indicator provides immediate status feedback, aiding fault location during inspections and reducing downtime in solar farms.
Yes. The fuse is CE marked and RoHS compliant, and it carries UL Listed and CSA Certified markings, along with IEC 60269 compatibility. This ensures regulatory alignment for global projects and simplifies cross-border procurement and installation in diverse markets.
Install as a bolted 3L unit with proper torque on the bolts per enclosure manufacturer's guidelines. Ensure 1500 Vdc rating is respected in wiring and insulation, and use matching Eaton Bussmann PV fuse components to preserve the protection scheme. The indicator aids quick fault verification during commissioning.
The fast-acting protection reduces energy losses during faults, lowers the risk of string damage, and minimizes downtime, contributing to improved uptime and lower maintenance costs. The compact 3L form factor saves enclosure space, enabling more efficient system layouts and easier serviceability.
