Surge Protection Device GSD3-230/IT (LT) for Lightning Protection Systems

Single-pole surge arresters of test class III, combined type. U0 = 230 V AC. Uoc (1,2/50) = 15 kV.

They are installed within II - III lightning protection zones (in accordance with GOST R IEC 62305-1 and SO-153-34.21.122). They are 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.
