Littelfuse is rising the amperage in solar string fuse choices


Littelfuse Inc., a global manufacturer of circuit protection, power control and sensing technologies, has added 35 to 60 amp models to its SPXV series of solar string fuses.

Littelfuse's 20 x 127 mm 1500 V DC solar fuses are designed to be integrated into an LFXV15 fuse block and cover holder and protect photovoltaic systems from overloads and short circuits to minimize damage to solar modules.

"Littelfuse recognizes the need to provide higher power protection while reducing costs in order to keep solar energy competitive with other forms of power generation," said Sakthidharan Krishnamoorthy, product manager for Littelfuse's industrial business. "With available amps of up to 60 A, more solar fuse chains can be pre-combined to reduce the number of inputs in combination boxes, thus reducing installation time and labor costs."

The main advantages of 35 to 60 amp SPXV series solar fuses include:

  • – Higher power protection in less space for more design flexibility
  • -Full range, fast-acting properties to protect against frequent errors in the event of low overload and short circuit
  • – Meets the standard requirements for photovoltaic fuses according to UL 248-19 and IEC 60269-6
  • -Product labels with QR codes that provide real-time access to part numbers, voltage and date codes to save time on product replacement and inventory
