Combined Arresters – Type 1 + Type 2

Protection Module for DEHNventil modular
• High discharge capacity due to powerful creepage discharge
spark gap
• Maximum system availability due to RADAX Flow follow
current limitation
• Easy replacement of protection modules without tools due
to module locking system with module release button
• Operating state / fault indication by green / red indicator
flag in the inspection window
• The plug-in protection module can be replaced without the
need to de-energise and without removing the distribution
board cover Combined Arresters – Type 1 + Type 2
In multipole protective circuits, we recommend replacing the complete
set of protection modules when one module fails.
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 – 2.

modules incorporate the complete monitoring circuit for controlling the
energy flow of the spark gap, the monitoring device and the operating
state / fault indicator.
The mechanical coding of the protection module prevents that the N-PE
protection modules are confused with the spark-gap-based module for
the phase conductors.
The module locking mechanism fixes the protection modules to the base
part. Protection modules can be easily removed without tools by simply
pressing the module release button.
