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.
