FVC10D/3+NPE-XXX 4poles surge arrester

FVC10D/3+NPE-XXX
FATECH FVC10D/3+NPE-XXX series are Class II+III/C+D/T2+T3 three-phase + NPE combined surge protective devices designed for TT power systems, providing complete surge protection for L1/L2/L3-N and N-PE circuits.With Imax 20kA, In 10kA, open circuit voltage Uoc 20kA and graded response speeds (L-N:≤25ns, N-PE:≤100ns), they provide stable and reliable overvoltage protection.Adopting separate wiring specifications for L-N and PE terminals, DIN-rail mounting, mechanical disconnection indicator (Red: Replace) and optional remote control contact, they are suitable for terminal low-voltage power distribution in industrial and commercial three-phase systems.

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

-High discharge current— Imax 20kA 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, N-PE.

-3 phase,4 poles.
