Spark-gap

FLP-SG50 V/1

Order number: A04054

pluggable module, visual fault signalling, module locking

  • encapsulated high-performance spark gap
  • installation at the boundary of zones LPZ 0 and LPZ 1 or higher, mainly to main distribution boards
  • for protection against impact of direct or indirect lightning strikes in the hardest application in heavy, chemical and energy industry
  • coordination with SPD type 2 (SLP-275 V) even without surge separating inductors
