FATECH surge arrester FV05D series for power supply system

Product catalog summary
Specifications:
The document outlines the specifications for remote control contact in surge protective devices. For AC systems, the maximum voltage (U) is ≤250V with a current (I) of ≤0.5A, using single-core wire with a maximum diameter of 1.5mm. For DC systems, the maximum voltage is ≤60V with a current of ≤0.1A, using multi-core wire with a maximum diameter of 1.3mm. Models without 'S' do not have remote control contact functionality.

Components and Features:
The device consists of a base part and MOV pluggable protection modules, suitable for lightning protection zones at boundary 1-2. It features metal oxide varistor components with high discharge capacity, low residual voltage, quick response, and reliable control via Thermo Dynamic Control disconnector. It includes a remote signaling contact for control devices and fault indication via a red mark in the inspection window. The protection mode covers L1, L2, L3, N-PE.

Model Information:
Models include FV05D/4-150(S), FV05D/4-275(S), FV05D/4-320(S), FV05D/4-385(S), and FV05D/4-440(S). They are tested under IEC/EN/VDE Class II+III/C+D standards and are suitable for TT and TN network types. Nominal voltage ranges from 110/220V~ to 220/380V~ with rated voltages (UC) from 150V~ to 440V~.

Performance Parameters:
The maximum discharge current (Imax) is 10kA, and the nominal discharge current (In) is 5kA. Voltage protective levels (Up) range from ≤0.6kV to ≤2.0kV. The open circuit voltage (Uoc) is 10kV, with a response time (tA) of ≤25ns. A recommended back-up fuse is 16A, and isolation resistance is >10 MΩ.

Installation and Environmental Conditions:
The device supports multi-core wire connections from 4mm to 25mm and mounts on a 35mm symmetrical rail (EN50022/DIN46277-3). It 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. It includes a mechanical disconnection indicator (Green: OK, Red: replace) and optional remote control contact.

Dimensions:
The device dimensions are 45mm x 66mm x 90mm, with additional specifications for mounting and connections provided.
