Surge voltage protection device GSD3-110/IT (LT), cat.no.300 115.

Single-pole surge arresters of test class III, combined type. U0 = 110 V AC. Uoc (1,2/50) = 2 kV. They are installed within II - III lightning protection zones (in accordance with GOST R IEC 62305-1 and SO-153-34.21.122). Designed to protect equipment from residual surge surges for circuits with IT grounding system.
