Surge Arrester Surge Surge Arrester T1 3+1 DIN Rail

Surge arrester type 1 50kA FLP-12.5 V/3+1 to 255V DC DIN rail varistor surge arrester for low voltage

Combined surge arrester type 1 (SPD T1) in a 3+1 configuration, designed for TT networks. Plug-in modules, fault indication, module locking. Contains a varistor and a spark gap.

Advanced protection for TT installations

FLP-12.5 V/3+1 is a combined surge arrester that protects TT installations. It combines a varistor lightning current arrester with a high-performance capsule spark gap. It provides protection against induced overvoltages, partial surges, and switching overvoltages.

Designed for installation at the boundary of LPZ 0 and LPZ 1 zones or higher. The device is equipped with lockable plug-in modules and a visual fault indicator.
