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.
Protection Mode:
The protection mode covers L1, L2, L3-N, and 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 from 4mm to 25mm. The device mounts on a 35mm symmetrical rail (EN50022/DIN46277-3). Operating temperature ranges from -40℃ to +80℃, with humidity from 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 MOV + GDT 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. Fault indication is provided via a red mark in the inspection window.
