Littelfuse has announced 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 1,500V DC solar fuses protect photovoltaic (PV) installations from overloads and short circuits to minimise 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 Recognised 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.
