DEHNvenCI

  • Spark-gap based combined lightning current and surge arrester with an integrated backup fuse capable of carrying lightning currents
  • Energy coordination with other arresters of the Red/Line product family
  • Low voltage protection level UP ≤ 1.5 kV (including backup fuse)
  • Maximum system availability due to RADAX Flow follow current limitation
  • Extinction of mains follow currents up to 100 kArms
  • High lightning current discharge capacity of 25 kA (10/350 µs)
  • Capable of protecting terminal equipment
  • Operating state / fault indication by green / red indicator flag in the inspection window

Circuit Interruption

The backup fuse is already integrated here. This means: reduced space requirement, lower installation costs, faster wiring, and shorter connecting cables. This concept can be found in the product ranges DEHNvenCI, DEHNbloc Maxi S, DEHNguard ... CI and V(A) NH...

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.

Lightning impulse current (10/350 µs) (Iimp ) 25 kA
Voltage protection level (UP ) ≤ 1.5 kV
Max. mains-side overcurrent protection not required (already integrated)
Approvals KEMA
