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.
