Eaton PV-350AF3 Photovoltaic Fuse - 50 kAIC, 1000 Vdc
Part Number: PV-350AF3
Quick Summary
PV fuse protects photovoltaic arrays by interrupting overcurrent in DC circuits for solar installations. Engineers often face nuisance tripping, limited visibility into fuse health, and mounting constraints that slow commissioning. This device is CE marked, RoHS compliant, and EAC certified, with IEC 60269 and UL 2579 certifications ensuring global compliance and safety. As a bolt-fixed, centre-status-indicator PV fuse for array combiners and disconnects, it simplifies installation and maintenance while delivering reliable protection. With a 350 A rating and a 1000 Vdc limit, it is well suited for utility-scale and commercial solar projects, helping meet protection standards while reducing downtime and service costs.

Eaton Bussmann - Products for sustainable energy
The PV-350AF3 provides robust protection for high-current solar installations, delivering 350 A with a 1000 Vdc rating and a 50 kAIC interrupt capability. This means fewer nuisance trips and safer disconnection during fault events, which translates into reduced downtime and improved system reliability for utility-scale and commercial PV plants. The device uses a Class gPV rating and the PV-AF3 fuse type with a Centre fuse status indicator, giving technicians immediate visibility of fuse health during maintenance and quick fault isolation in field conditions. Bolt fixing supports secure mounting in standard enclosures, enabling straightforward retrofits and reliable operation in harsh environments. Global compliance (CE, RoHS, EAC) coupled with IEC 60269 and UL 2579 certifications ensures accepted performance across diverse markets. Watt losses of 51 W reflect a balanced thermal profile suitable for continuous operation in PV arrays, while the compact size aids compatibility with existing busbar layouts and space-constrained installations. This fuse integrates smoothly with Eaton Bussmann PV protection products, offering consistent electrical characteristics and simplifying procurement, stocking, and maintenance planning for engineering teams.

FAQs
Install the PV-350AF3 using its bolt-fixing configuration in a compatible fuse holder or enclosure. Ensure the centre fuse status indicator is visible for easy health checks. Confirm voltage and current ratings (1000 Vdc, 350 A) match your array design and maintain proper clearance and torque per enclosure guidelines to prevent overheating and ensure reliable operation.
The PV-350AF3 is rated for 350 A and 1000 Vdc, with a 50 kAIC interrupt rating. It is classified as Class gPV and intended for photovoltaic array protection. These ratings make it suitable for large solar arrays and protect critical components such as combiners and disconnects from overcurrent events.
Yes. The PV-350AF3 is designed for integration within the Bussmann PV protection family and accommodates bolt-fixed connections. When substituting, verify catalog compatibility (PV-AF3 family) and ensure electrical and mechanical fit within the existing enclosure and busbar arrangements.
The device is CE Marked, RoHS Compliant, and EAC certified, with IEC 60269 and UL 2579 certifications. These recognitions support global product acceptance, regulatory compliance, and safer operation across diverse markets and project specifications.
The centre status indicator provides clear fuse health visibility, reducing inspection time and enabling proactive maintenance. The high interrupt rating and robust ratings lower the risk of unexpected outages, which translates to reduced downtime, safer field service, and improved lifecycle cost for PV protection systems.
