SPF SERIES SOLAR FUSES
1000 V dc • 1–30 A
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 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 multiple ampere ratings to match specific
requirements in a variety of applications.
Features/Benefits
Full range, fast-acting fuse helps eliminate common low-
overload 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
