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 14 ampere ratings to match specific
requirements in a variety of applications.
