FLP-12,5 - V / 3 + 1
SPD class 1 + 2
three-pole lightning arrester varistor with replaceable modules. Varistor surge currents and lightning arrester for indoor N-PE, combined in a 3 + 1 block. Set to low voltage distribution networks in buildings III and IV of the lightning protection levels PIP at the border zones lightning LPZ 0-LPZ 1 and higher. It is used in three-phase systems with a system of grounding TT.
serves for protection against lightning impacts partial currents induced by surge and lightning strikes against switching surges. .. The visual fault indicator
