Surge Arresters SLP-275 VD/3+1 SLP-275 VDS/3+1 SPD type 2 – surge arrester Combination of 3-pole varistor surge protection and an encapsulated spark gap connected in the mode 3+1. To be installed in low-voltage distributions at the boundary of LPZ 1 and LPZ 2 zones to protect distributions and equipment against the overvoltage effects induced during a lightning strike and to prevent switching overvoltage. Optional remote status signalling - S design.
