  • Application-optimised and prewired spark-gap-based type 1 and type 2 combined lightning current and surge arrester
  • Compact design due to space-saving spark gap technology with a width of only 1 module / pole
  • Fulfils the minimum requirements on the lightning current discharge capacity according to IEC 60364-5-53
  • Allows compact lightning equipotential bonding including protection of terminal equipment
  • Discharge capacity up to 50 kA (10/350 µs)
  • Operating state / fault indication by green / red indicator flag in the inspection window
  • High follow current extinguishing capacity (Ifi = 25 kArms)
