Littelfuse releases 400PV Fuse series ideal for solar shingles

Littelfuse has announced its latest product, the 400PV fuse series – a size 2410 SMD (Surface Mount Design) circuit protection component with low resistance for solar applications.

The 400PV is specifically designed to address the latest trend in solar roofing by enabling PV shingles that integrate both the shingles with the PV cells while providing protection that meets the UL 248-19 standard for PV applications .

“The innovation of the 400PV Fuse series allows the next generation of smart home designs to use photovoltaic roof shingles to power everything in a home that needs power,” said Boris Golubovic, vice president of marketing and strategy at Littelfuse. “The protection provided by these PV fuses helps ensure the operational life, serviceability and safety of solar residential and building applications.”

The 400PV Fuse series complies with the UL 248-19 standard for the design of PV power systems. It avoids annoying opening thanks to its high reliability and a maximum interrupting current of 10,000 A at nominal voltage. 400PV saves PC board space with Surface Mount Design (SMD) and 2410 size, suitable for both lead-free and lead-free soldering, and it is eco-friendly, 100% lead-free, halogen-free, and RoHS compliant.

The 400PV Fuse series is available in tape and reel packaging. Sample requests can be made through authorized Littelfuse distributors around the world. For a list of Littelfuse distributors, please visit
