FATECH FV40C/4-XXX series are Class II (Type 2) four‑pole AC surge protective devices designed for TT and TN three-phase power systems, providing comprehensive surge protection for L1/L2/L3/N‑PE circuits. With Imax 80kA, In 40kA and ultra-fast response ≤25ns, they deliver stable, efficient and reliable protection performance. Featuring mechanical status indication (Green: OK, Red: Replace), DIN-rail mounting and optional remote contact, they ensure durable operation and are suitable for surge protection of three-phase low-voltage power distribution systems in industrial and commercial scenarios.

FATECH FV50B/1-XXX series are Class I Type 1 single-pole AC surge protective devices compatible with TT, TN and IT power systems. Featuring high surge capacity (Iimp 50kA, In 50kA), fast response (≤100ns) and mechanical status indication (Green: OK, Red: Replace), they provide reliable lightning and transient surge protection for L/N-PE circuits. With DIN-rail mounting, high insulation performance and optional remote contact, they are suitable for various low-voltage power scenarios to ensure stable and safe operation of electrical equipment.

FATECH FV50B/2-XXX series are Class I Type 1 two-pole AC surge protective devices designed for TT and TN power systems. With high surge current capacity (Iimp 50kA, In 50kA), fast response ≤100ns and mechanical status indication, they provide robust lightning surge protection for L-PE and N-PE circuits. Featuring DIN‑rail mounting, high insulation, wide voltage options and optional remote contact, they ensure stable and safe operation for residential, commercial and industrial power distribution.

FATECH FV50B/3-XXX series are Class I Type 1 three‑pole AC surge protective devices specially designed for IT power systems.
