FV30B+C/3+NPE-XXX In30kA 3P ac surge protection device

FV30B+C/3+NPE-XXX
FATECH FV30B+C/4-XXX series are Class I+II (Type 1+2) four‑pole AC surge protective devices for TT and TN three‑phase power systems. With Iimp 7kA, Imax 60kA, In 30kA and ultra‑fast response ≤25ns, they provide full combined lightning and surge protection for L1/L2/L3/N‑PE circuits. Featuring mechanical status indication, DIN‑rail mounting and optional remote contact, they ensure stable, reliable and long‑lasting surge protection for industrial and commercial 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: L1,L2,L3-N,N-PE.
