The device of protection against impulse overvoltages RST 4P 230/RVS, cat.No.402 518.

UZIP RST 4P 230/RVS, TU 3428-002-79740390-2007 are designed to protect a pair of 2-wire circuits of signal lines of control and measurement systems, four signal lines with a common reference potential from impulse overvoltages (lightning protection, protection from electrostatic discharges, etc.) within 1 - 2 zones of lightning protection in accordance with GOST R IEC 62305-1-2010. The devices are assembled according to the three-stage protection scheme: arrester-varistor-suppressor. They are produced for nominal operating voltage Uo= 230 V AC/DC, nominal current IL= 3 A. Data transmission speed up to 1 Mbit/s. Capable of passing the rated discharge current In (8/20)= 5 kA; ITotal (8/20)=20 kA.The devices are placed in a 7.4 mm thick case for installation on a 35 mm DIN-rail. The number of protected conductors is 4.
