FV10D/4-XXX 20KA 3 phase surge protection device

FV10D/4-XXX
FATECH FV10D/4-XXX series are Class II+III/C+D/Type2+3 four-pole combined surge protective devices suitable for TT and TN power systems, providing full surge protection for L1/L2/L3/N‑PE circuits.With Imax 20kA, In 10kA, open circuit voltage Uoc 20kA and fast response time ≤25ns, they offer stable and reliable overvoltage protection.Featuring mechanical status indication (Green: OK, Red: Replace), DIN-rail mounting and optional remote control contact, they are ideal for industrial and commercial three-phase terminal low-voltage 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 metal oxide vristor 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-PE.
