Description
The SPF_CN 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_CN 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
