Description

The SPF_CN 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_CN series is UL Listed to safely interrupt faulted circuits up to this demanding voltage level. Littelfuse offers multiple ampere ratings to match specific requirements in a variety of applications. Features/Benefits Full range, fast-acting fuse helps eliminate common low-overload faults Prevents power generation losses due to nuisance tripping from changes in temperature PCB mount and dead-front holder options available
