FV50C/2-XXX In50kA 2poles voltage surge suppressor

FV50C/2-XXX

FATECH FV50C/2-XXX series are Class II (Type 2) two‑pole AC surge protective devices designed for TT and TN power systems. With Imax 100kA, In 50kA and ultra‑fast response ≤25ns, they provide high‑performance surge protection for L‑PE and N‑PE circuits. Featuring mechanical fault indication, DIN‑rail mounting and optional remote contact, they ensure stable and heavy‑duty surge protection for residential, commercial and industrial power distribution systems.

-Consisting of a base part and MOV pluggable protection modules.

-For using in the lightning protection zones concept at boundary 1-2.

-The core parts are metaloxidevristor components with high discharge capacity.

-Low residual voltage and quick response.

-Reliable control thanks to Thermo Dynamic Control disconnector.

-With remote signaling contact for control device.

-Fault indication via red mark in the inspection window.

-Protection mode: L-PE,N-PE.
