DEHNsolid
• Coordinated spark-gap-based lightning current arrester
• Extremely high lightning current discharge capacity
up to 200 kA (10/350 µs)
• Low voltage protection level UP ≤ 2.5 kV
• Extremely robust design for installation on busbars
or mounting plates

For protecting low-voltage consumer installations against surges and even direct
lightning strikes. For installation in conformity with the lightning protection zone
concept at the boundaries from 0A – 1.

DSO 1 255: Coordinated single-pole lightning current arrester with an extremely high lightning current discharge capacity
