DEHNbloc Maxi 1 CI 440 / 760 FM

  • Spark-gap-based lightning current arrester with an integrated backup fuse capable of carrying lightning currents in a compact enclosure
  • Extremely high lightning current discharge capacity of 35 kA (10/350 µs)
  • Low voltage protection level (including backup fuse)
  • High follow current extinguishing capability and limitation thanks to RADAX Flow technology
  • Energy coordination with other arresters of the Red/Line product family
  • 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.

Technical data

SPD according to EN 61643-11 / IEC 61643-11 type 1 / class I
Maximum continuous operating voltage (a.c.) (UC ) 440 V (50 / 60 Hz)
Lightning impulse current (10/350 µs) (Iimp ) 35 kA
Voltage protection level (UP ) ≤ 2.5 kV
Max. mains-side overcurrent protection not required
Type of remote signalling contact changeover contact
