Surge protection device RIF-E-I+II 275/12.5 c (4+0) Streamer 114104

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