FV12.5B+C/3-xxxxPVN(S) In20kA surge arrester types

FV12.5B+C/3-1000PVN(S)
FATECH FV12.5B+C/3-1000PVN(S) and FV12.5B+C/3-1200PVN(S) are Class I+II Type 1+2 DC surge protective devices for PV system DC side. With fast response, low residual current, mechanical status indication and optional remote contact, they provide reliable lightning and surge protection for photovoltaic systems with DIN‑rail mounting and high insulation performance.

-DC surge Protective decice specially used for photovoltaic system less than 1000Vdc.

-The core parts are metal oxide vristor components with high discharge capacity.

-With reliable control thanks to Thermo Dynamic Control disconnector.

-Without remote signaling contact for control device.

-Fault indication via red mark in the inspection windows.
