FVC20C/4-XXX 40kA 4P surge protector for ac unit

FVC20C/4-XXX
FATECH FVC20C/4-XXX series are Class II/C/T2 four-pole AC surge protective devices designed for TT and TN power systems, providing comprehensive surge protection for L1/L2/L3/N‑PE circuits. With Imax 40kA, In 20kA and fast response time ≤25ns, they offer stable and efficient overvoltage protection.Adopting separate wire specifications for L-N and PE terminals, DIN-rail mounting, mechanical disconnection indicator (Red: replace) and optional remote control contact, they are widely applied in industrial and commercial low-voltage power distribution systems.

-Narrow size surge protective device special design for saving installation space— width 9mm/pole.

-High discharge current— Imax 40kA per pole.

-Indication window for clear display of SPD status— each pole with one indication window.

-Remote controlling function -for your option.

-Pluggable module— convenient for maintenance.

-Protection mode — L1,L2,L3, N-PE.

-3 phase,4 poles.
