Eaton PVS355A-3L-BU-15 Photovoltaic Fuse - UL Listed
Part Number: PVS355A-3L-BU-15
Quick Summary
Eaton PVS355A-3L-BU-15 Photovoltaic fuses protect solar arrays and inverters in PV installations. Engineers seek reliable, high-current DC protections that don’t compromise safety or space. These units meet IEC 60269, UL Listed, CE marking, and RoHS requirements, delivering proven reliability for 1500 V PV strings. With 355 A rating and 100 kAIC interrupt capability, they guard against arcing and cascade faults. The non-indicating design keeps fault indicators simple, while 3L size and blade-with-bolt-hole mounting simplify installation and retrofit. This combination reduces downtime, minimizes maintenance costs, and supports scalable protection across commercial and utility-scale projects. Low watt losses of 57 W help keep inverter efficiency high and cooling loads down.

Feature 355 A rating and 1500 V DC capability enable high-current protection for modern PV strings, delivering rapid interruption to prevent cascading failures. Business impact includes reduced damage to modules and inverters, lower replacement costs, and improved system uptime in utility-scale and commercial installations. Application: PV arrays and inverters demanding robust, high-voltage protection while maintaining efficiency. The Class gPV designation and 100 kAIC interrupt rating ensure safe operation under fault conditions, supporting compliant, reliable performance in harsh environments. Framing and mounting compatibility with blade-through bolt-hole assemblies simplifies installation, reduces labor time, and enables straightforward retrofits in existing cabinets. A non-indicating fuse indicator minimizes visual maintenance, while a compact 3L form factor saves cabinet space and supports modular protection strategies. Long-term reliability is reinforced by CE, RoHS, and IEC 60269 compliance and UL Listing, addressing both safety and regulatory concerns. Watt losses of 57 W contribute to cooler operation and extended inverter life, a meaningful efficiency advantage in continuous PV service.

FAQs
The PVS355A-3L-BU-15 uses a 3L fuse size and is designed for blade with bolt hole mounting, simplifying retrofit into existing enclosures. With a length of 201.4 mm and a compact 74 mm square footprint, it fits standard PV cabinet layouts. Its non-indicating fuse indicator keeps field panels uncluttered, while UL Listed and CE RoHS certifications provide clear compliance guidance for installation codes and safety requirements.
This fuse is rated for 355 A continuous operation at 1500 V DC, with a 100 kAIC interrupt rating to handle high fault currents without arcing. The Pre-arc I2T of 250,000 indicates a controlled pre-arcing energy threshold, reducing damage during fault events. These specifications translate to fast, reliable protection for PV strings and inverters, preserving system integrity during surge or short-circuit conditions.
The device carries IEC 60269 certification and UL Listing, with CE marking and RoHS compliance. These certifications ensure compliance with global safety, performance, and environmental standards, reducing regulatory risk for installations in North America and international projects while facilitating easier procurement through recognized quality marks.
Yes. With watt losses of 57 W and a non-indicating design, the PVS355A-3L-BU-15 is suitable for continuous PV service in inverters and string boxes. Its high current and voltage ratings support large-scale arrays, and the 3L form factor plus bolt-hole mounting streamlines integration into existing protection schemes, minimizing downtime and maintenance complexity.
The fuse offers high fault tolerance (355 A, 1500 V, 100 kAIC) and low heat generation (57 W), which translates to lower cooling requirements and longer inverter life. The robust certifications (UL Listed, IEC 60269, CE, RoHS) reduce compliance risk and maintenance overhead. Easy installation and retrofit capability further shorten project timelines and enhance lifecycle value for PV projects.
