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.
Components and Features:
The device consists of a base part and pluggable MOV protection modules, designed for use in 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 through a Thermo Dynamic Control disconnector. It includes a remote signaling contact for control devices and a fault indication via a red mark in the inspection window. The protection mode is L-PE, N-PE.
Model Information:
The models listed are FV10D/2-150(S), FV10D/2-275(S), FV10D/2-320(S), FV10D/2-385(S), and FV10D/2-440(S). They are tested under IEC/EN/VDE Class II+III/C+D standards and are suitable for TT and TN network types. The nominal voltage is 110/220V~ or 220/380V~ depending on the model, with a rated voltage (UC) ranging from 150V~ to 440V~.
