FATECH surge arrester FV30C/1+NPE-275 for ac 1 phase power supply

Product catalog summary
Specifications:
The document outlines the specifications for remote control contact in surge protective devices. It specifies the range of signal access 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.
Model Information:
The models listed include FV30C/1+NPE-150(S), FV30C/1+NPE-275(S), FV30C/1+NPE-320(S), FV30C/1+NPE-385(S), and FV30C/1+NPE-440(S). These models are tested under IEC/EN/VDE Class II/C and are suitable for TT network types with protection modes L-N and N-PE.
Electrical Characteristics:
Nominal voltage is specified at 50(60)Hz with various rated voltages (UC) ranging from 150V to 440V. The maximum discharge current (Imax) is 60kA or 50kA, and the nominal discharge current (In) is 30kA or 25kA. 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.
Installation and Operation:
Recommended back-up fuse is 125A, with isolation resistance greater than 10 MΩ. I/O connections require multi-core wire ranging 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, and the housing material is UL94 V-0.
Additional Features:
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 protection modules with metal oxide varistor components for high discharge capacity. It is designed for use in lightning protection zones at boundary 1-2, offering low residual voltage and quick response. Fault indication is provided via a red mark in the inspection window.
