Description
The SPF Solar Protection Fuse series was specifically designed for
photovoltaic (PV) systems. This family of Midget style fuses (10
x 38mm) can safely protect PV modules and conductors from
reverse overcurrent conditions despite the associated challenges
of DC power.
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 con-
ductor runs. Standard midget designs are not optimized for Solar
Protection requirements. However, the SPF series is UL Recog-
nized to safely interrupt circuits up to this demanding voltage level.
Littelfuse offers thirteen ampere ratings to match designers’ spe-
cific requirements in applications including combiner
boxes, inverters and battery charge controllers.
