DEHNbloc

  • Encapsulated non-exhausting creepage discharge spark gap
  • RADAX Flow spark gap technology with high follow current limitation
  • Energy coordination with other arresters of the Red/Line product family
  • Can also be used upstream of meter panels due to its high insulation resistance
  • Multifunctional terminal for connecting conductors and busbars
  • Single-pole and three-pole version (lightning impulse currents up to 100 kA depending on the system configuration)
  • Modular single-pole version also available

DEHNbloc H
