DEHNbloc modular

  • Coordinated spark-gap-based lightning current arrester consisting of a base part and a plug-in protection module
  • Maximum system availability due to RADAX Flow follow current limitation
  • No tripping of 32 A gG fuses up to short-circuit currents of 50 kArms
  • Discharge capacity up to 50 kA (10/350 µs)
  • Directly coordinated with DEHNguard surge protective devices without additional cable length
  • Low voltage protection level
  • Operating state / fault indication by green / red indicator flag in the inspection window
  • Easy replacement of protection modules without tools due to module locking system with module release button

Wave breaker function

In the case of spark-gap-based type 1 arresters, the entire current flows through the type 1 arrester during the discharge process. Like a wave breaker, the incoming energy is greatly broken down, which significantly relieves the downstream SPDs. All type 1 arresters in the Red/Line product range feature the WBF wave breaker function.
