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 TN-C type earthing system.
