Specifications:
The document outlines the specifications for remote control contact in surge protective devices. For AC systems, the maximum voltage (U) is ≤250V with a current (I) of ≤0.5A, using single-core wire with a maximum diameter of 1.5mm. For DC systems, 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 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, quick response, and reliable control via Thermo Dynamic Control disconnector. It includes a remote signaling contact for control devices and fault indication via a red mark in the inspection window. The protection mode covers L1, L2, L3, N-PE.
