FATECH surge arrester FV10D/1+NPE-320S for AC Class 3 power supply
The document outlines the specifications for remote control contact in surge protective devices. It details the signal access range and recommended wire specifications for both AC and DC systems. For AC, the maximum voltage is 250V with a current of 0.5A, using single-core wire up to 1.5mm. For DC, the maximum voltage is 60V with a current of 0.1A, using multi-core wire up to 1.3mm. Models without 'S' do not have remote control contact functionality.
The models listed include FV10D/1+NPE-150(S), FV10D/1+NPE-275(S), FV10D/1+NPE-320(S), FV10D/1+NPE-385(S), and FV10D/1+NPE-440(S). These models are tested under IEC/EN/VDE Class II+III/C+D standards and are suitable for TT network types with protection modes L-N and N-PE.
Nominal voltage is specified at 50(60)Hz with various rated voltages (UC) ranging from 150V to 440V AC. The maximum discharge current (Imax) is 20kA, and the nominal discharge current (In) is 10kA. Voltage protective levels (Up) vary for L-N and N-PE connections, with response times of ≤25ns for L-N and ≤100ns for N-PE.
Recommended back-up fuse is 125A, with isolation resistance greater than 10 MΩ. I/O connections support multi-core wire from 4mm to 25mm. The device mounts on a 35mm symmetrical rail (EN50022/DIN46277-3) and operates within a temperature range of -40℃ to +80℃, humidity of 30% to 90%, and altitude up to 3000m. The degree of protection is IP20, with housing material rated UL94 V-0.
The device includes a mechanical disconnection indicator (green for OK, red for replace) and optional remote control contact. It consists of a base part and pluggable MOV + GDT protection modules, designed for use in lightning protection zones at boundary 1-2. It features low residual voltage, quick response, and reliable control with a Thermo Dynamic Control disconnector. Fault indication is provided via a red mark in the inspection window.
