Fv-1250/3S

This series of protectors for photovoltaic systems have been developed to protect against discharges and surges produced by lightning strikes in the DC part of said systems.

The protection consists of two stages of varistors equipped with thermal disconnectors that indicate the failure of the element through a window. It has a remote output (indication contact).
