ClassⅠ/T1/ B,Iimp 50kA

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. With high surge capacity (Iimp 50kA, In 50kA), fast response ≤100ns and mechanical status indication, they provide strong lightning surge protection for L1/L2/L3‑PE circuits. Supporting DIN‑rail mounting, high insulation, wide voltage selection and optional remote contact, they ensure stable and safe operation of three‑phase power equipment in industrial and commercial scenarios.

FATECH FV50B/4-XXX series are Class I Type 1 four‑pole AC surge protective devices suitable for TT and TN power systems. With Iimp 50kA, In 50kA, fast response and mechanical status indication, they provide high‑energy lightning surge protection for three‑phase distribution networks, supporting DIN‑rail installation and optional remote contact for reliable industrial and building power safety.
