FATECH surge arrester FV25B/2-385 for Iimp25ka AC power system
Product catalog summary
Specifications:
The document outlines the specifications for remote control contact and signal access. 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.

Installation and Operation:
I/O connections for L-N use multi-core wire of 10mm to 25mm, and PE uses multi-core wire greater than 16mm. The device mounts on a 35mm symmetrical rail (EN50022/DIN46277-3). It operates in temperatures from -40℃ to +80℃, humidity from 30% to 90%, and altitudes up to 3000m. The degree of protection is IP20, and the housing material is UL94 V-0. A mechanical indicator shows the disconnection status (Green: OK, Red: replace).
