SPF Solar Fuse
The SPF Solar Protection Fuse series has been specifically designed for the protection of photovoltaic (PV) systems. This family of Midget style fuses (10x38 mm) can safely protect PV (photovoltaic) modules and conductors from reverse overcurrent conditions.
As PV systems have grown in size, so have the corresponding voltage requirements. This increase in system voltage has typically been intended to minimize power loss associated with long conductor runs. Standard circuit protection devices are not designed to completely protect photovoltaic panels. However, the SPF series is UL Listed to safely interrupt faulted circuits up to this demanding voltage level.
Littelfuse offers various ampere ratings to match specific requirements in a variety of applications.
Features and Benefits
  • Designed to both UL and IEC photovoltaic specifications
  • UL 2579 Listed 1000 VDC maximum
  • 1-30 A ratings available
  • 20,000 A Interrupting Rating
  • Both PCB mount and dead-front holder options available
