FV10D/4-275S Type 2+3 10kA ac surge protector

FV10D/4-275S
FATECH FV10D/4-275S is a 4-pole, DIN‑rail mountable Type 2 AC surge protector (SPD) with pluggable MOV modules. Designed for low‑voltage three‑phase power distribution systems, it delivers In=10kA, Imax=20kA (8/20μs) lightning and switching surge protection, with remote signaling and visual fault indication for reliable equipment safeguarding.

-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.

The remote signaling contact monitors the working status of the SPD. It sends an alarm signal when the SPD fails or needs replacement, enabling real-time monitoring and maintenance.

FATECH SPDs feature TUV & CE certification, stable performance, long service life, and professional technical support. They are widely used in PV, industrial, lighting, network, and residential applications with high cost-performance.

Yes, we support OEM and ODM services

SPDs are widely used in residential buildings, commercial centers, industrial factories, solar PV power stations, LED lighting, security CCTV, telecom base stations, data centers, and infrastructure projects.

Effective grounding provides a low-resistance path for surge current to discharge quickly. Poor grounding will reduce protection performance, increase residual voltage, and may cause equipment damage.
