FATECH surge arrester FV30B+C/2-150 for protecting of power system

Product catalog summary

Specifications:
The document outlines the specifications for remote control contact in surge protective devices. For AC, the maximum voltage is 250V with a current of 0.5A, using single-core wire with a maximum diameter of 1.5mm. For DC, 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.

Model Information:
The models listed include FV30B+C/2-150(S), FV30B+C/2-275(S), FV30B+C/2-320(S), FV30B+C/2-385(S), and FV30B+C/2-440(S). These models are tested under IEC/EN/VDE Class I+II/B+C standards and are suitable for TT and TN network types. The protection mode is L-PE, N-PE.

Electrical Characteristics:
Nominal voltage is 110/220V~ to 220/380V~ with a rated voltage (UC) ranging from 150V~ to 440V~. The impulse current (I imp) is 7kA, with a maximum discharge current (Imax) of 60kA and a nominal discharge current (In) of 30kA. The voltage protective level (Up) ranges from ≤0.9kV to ≤2.2kV, and the response time (tA) is ≤25ns. A recommended back-up fuse is 160A, and isolation resistance is greater than 10 MΩ.

Installation and Operation:
The device uses multi-core wire connections ranging from 4mm to 25mm and mounts on a 35mm symmetrical rail (EN50022/DIN46277-3). It operates in temperatures from -40℃ to +80℃, with humidity levels of 30% to 90%, and up to an altitude of 3000m. The degree of protection is IP20, and the housing material is UL94 V-0. A mechanical indicator shows green for OK and red for replacement.

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, and quick response. It includes a Thermo Dynamic Control disconnector for reliable control and a remote signaling contact for control devices. Fault indication is provided via a red mark in the inspection window.
