FV20C/3-XXX type2 In20kA surge arrester

FV20C/3-XXX
FATECH FV20C/3-XXX series are Class II/C/Type2 three-pole AC surge protective devices specially applied to IT power systems, providing comprehensive surge protection for L1-PE, L2-PE and L3-PE circuits. With Imax 40kA, In 20kA and fast response time ≤25ns, they deliver stable and reliable overvoltage protection. Featuring mechanical status indication (Green: OK, Red: Replace), DIN-rail mounting and optional remote control contact, they are suitable for industrial three-phase low-voltage power distribution equipment.

-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.

-Faultindication via red mark in the inspection window.

-Protection mode: L1,L2,L3-PE.
