Surge Protection Device K2R SVR25-230 S for Reliable Protection in TN-C Systems

Single-pole surge arresters of test class I, II, III combined type for networks with earthing system type TN-C. Uo = 230/300 V AC/DC. Iimp(10/350)= 25 kA.

With remote signalling. Installed within 0A(V) - 2 lightning protection zones (in accordance with GOST R IEC 62305-1 and SO-153-34.21.122). They are intended for protection of equipment in low-voltage power distribution systems with air or cable power input.

The device is mounted on a 35 mm DIN-rail by means of a special latch on the rear side of the housing. They are assembled on the basis of zinc-oxide varistors and a gas-filled arrester included in the pole in series - "valve arrester". Eliminate leakage currents.
