FLP-275 V/3+1 Three Phase Type 1&2 SPD 8 kA
Lightning Current Arresters
FLP-275 V/3+1
FLP-275 V/3S+1
SPD type 1 and type 2
Replaceable module, visual fault signaling
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 0B and LPZ 1 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).
