DEHNbloc Maxi 440 / 760
- Spark-gap-based lightning current arrester
- Extremely high lightning current discharge capacity
- High follow current extinguishing capability and limitation due RADAX Flow technology
- Directly coordinated with DEHNguard surge protective devices without additional cable length
- Operating state / fault indication by green / red indicator flag in the inspection window
