• TNS Protection - 8595090517221

SPD type 2 – surge arrester 4-pole arrester for 3-phase TNS networks 4-pole varistor surge protection to

be installed in low-voltage distributions at the boundary of LPZ 1 and LPZ 2 zones to protect the distributions

and equipment against overvoltage effects induced during a lightning strike and to prevent switching

overvoltage. Optional remote status signalling (S).
