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.
