Description

The SPF Solar Protection Fuse series has been specifically

designed for the protection of photovoltaic (PV) systems.

This family of midget-style fuses (10 x 38 mm) can safely

protect PV modules and conductors from reverseovercurrent 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 multiple ampere ratings to match specific

requirements in a variety of applications.

Features/Benefits

 Full range, fast-acting fuse helps eliminate common lowoverload faults  Prevents power generation losses due to nuisance

tripping from changes in temperature

 Both PCB mount and dead-front holder options available

Applications

 Inverters  Combiner boxes

 Battery charge controllers
