New solar fuses offer higher amperage in a streamlined, single case design

Littelfuse announced today the expansion of its SPXI series in-line solar fuses to include 35 to 60 amperage models. Designed to integrate into in-line assemblies within a wire harness, these 1500 V DC solar fuses protect photovoltaic (PV) installations from overloads and short circuits to minimize damage to solar panels.

“Littelfuse understands that the demands on critical solar power systems as a source of clean, renewable energy are growing,” said Sakthidharan Krishnamoorthy, product manager, Littelfuse Industrial Business Unit. “We are committed to providing higher amperage protection in a design that can be easily retrofitted within existing in-line configurations to stay ahead of the increasing needs of the industry.”

Other key benefits of the higher amperage solar SPXI in-line string fuses include:

• A single body case design to increase reliability and simplify retrofitting within existing solar power systems
• UL Recognized to UL248-19 standard, with 50 kA DC interrupting rating
• Product labels with QR codes offering real-time access to part numbers, voltage, programming terms, and date codes to save time with product replacements and inventorying
