FV40C/1-XXX 1pole surge arrester for power system

FV40C/1-XXX

FATECH FV40C/1-XXX series are Class II (Type 2) single‑pole AC surge protective devices suitable for TT, TN and IT power systems. With Imax 80kA, In 40kA and ultra‑fast response ≤25ns, they provide reliable surge protection for L/N‑PE circuits. Featuring mechanical status indication (Green: OK, Red: Replace), DIN‑rail mounting and optional remote control contact, they ensure stable and durable surge protection for various low‑voltage power applications in residential, commercial and industrial scenarios.

-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/N-PE.
