Surge protection device RIF-E-I+II+III 275/12.5 s (1+1) Streamer 112109

Two-pole SPD class I+II+III combined type. The SPD consists of one replaceable varistor module, one replaceable module with a spark gap, and a base for connection to the network. The SPD is designed to protect equipment in low-voltage circuits up to 1000 V from direct and remote lightning discharges at air or cable power inlets. The SPD withstands current loads corresponding to SPD class I, in terms of impulse voltage limitation capability, corresponding to SPD class II and SPD class III. It is installed within 0A(V) – 1 lightning protection zones (in accordance with GOST R IEC 62305-1 and SO-153-34.21.122). The recommended fuse rating is at least 125 A gL/gG.
