Surge Protection Device GSD3-110/IT (LT) for Enhanced Equipment Safety

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. Visual control of the operating state of the overvoltage arresters is carried out by means of a green-coloured LED in the thermal release circuit.

For remote monitoring the devices are equipped with a dry contact for remote signalling.
