Surge protective device RIF-E-I+II 275/12.5 s (3+1) Strimer 114103

Four-pole Type I+II combined SPD. The SPD is made of three varistor modules and one module with a spark gap, and a base for network connection and mounting on a 35 mm DIN rail. The SPD is designed to protect equipment in low-voltage circuits up to 1000 V from direct and remote lightning discharges with air or cable power supply inlets. The SPD withstands current loads corresponding to Type I SPD, and in terms of impulse voltage limiting capability permissible for equipment insulation, it corresponds to Type II SPD. The SPD is equipped with remote signaling contacts for working element failure. Installed within 0A(B) – 1 lightning protection zones (in accordance with GOST R IEC 62305-1 and SO-153-34.21.122). Used for networks with grounding systems: TN-S, TT. Recommended fuse rating 125-200 A gL/gG
