FATECH surge arrester FV30B+C/1+NPE-440 for 1 phase ac power

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 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 Numbers:
The models listed include FV30B+C/3+NPE-150(S), FV30B+C/3+NPE-275(S), FV30B+C/3+NPE-320(S), FV30B+C/3+NPE-385(S), and FV30B+C/3+NPE-440(S).

Test Class and Network Type:
The devices are tested under IEC/EN/VDE Class I+II/B+C and are suitable for TT network types. The protection mode is L-N, N-PE.

Electrical Characteristics:
Nominal voltage is 110/220V~ to 220/380V~. Rated voltage (UC) ranges from 150V~ to 440V~. Impulse current (Iimp) is 7kA, with a maximum discharge current (Imax) of 60kA and nominal discharge current (In) of 30kA. Voltage protective levels (Up) vary from ≤0.9kV to ≤2.2kV for L-N and ≤1.5kV for N-PE. Response time is ≤25ns for L-N and ≤100ns for N-PE.

Installation and Operation:
Recommended back-up fuse is 160A. Isolation resistance is greater than 10 MΩ. I/O connections use multi-core wire ranging from 4mm to 25mm. Devices are mounted on a 35mm symmetrical rail (EN50022/DIN46277-3). Operating temperature ranges from -40℃ to +80℃, with humidity between 30% and 90%, and altitude up to 3000m. The degree of protection is IP20, and housing material is UL94 V-0.

Additional Features:
The devices include a mechanical disconnection indicator (green for OK, red for replace) and optional remote control contact. They consist of a base part and MOV + GDT pluggable protection modules, suitable for lightning protection zones at boundary 1-2. They feature metal oxide varistor components with high discharge capacity, low residual voltage, quick response, and reliable control via Thermo Dynamic Control disconnector. Fault indication is provided via a red mark in the inspection window.
