SPF Solar Protection Fuses are designed specifically for photovoltaic (PV) systems. It safely protects PV (photovoltaic) modules and conductors from reverse overcurrents.

As photovoltaic (PV) system applications have grown in size, their corresponding voltage requirements have increased.

The increased system voltages are usually designed to minimize the energy consumption associated with conductor overruns.

Standard circuit protection devices are not designed to fully protect PV panels.
