Surge Protection Device GSV123-230/25 - Essential for TN-S Systems

Two-pole ultrasonic protection devices of test classes I, II, III of limiting type for networks with earthing system of TN-S type. Uo = 230 V AC. Iimp(10/350)= 25 kA.

Made according to the scheme for protection against longitudinal overvoltages in circuits "wire - ground". They are installed within 0A(V) - 1 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 up to 1000 V at air or cable power supply entry.
