Protection Module for DEHNbloc 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 switch-
ing off the mains voltage or removing the vertical cover

DB M MOD ...: Spark-gap-based protection module 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.

The spark-gap-based protection modules for devices of the DEHNbloc M As with all modular protective devices, protection modules can be easily
family incorporate the complete protective circuit including the RADAX replaced without tools by simply pressing the module release button.
Flow spark gap and the monitoring circuit for controlling the energy flow. Avoid additional, short-notice and unplanned maintenance jobs.
The spark gap monitoring system and the operating state / fault indicator In multipole protective circuits, we recommend replacing the complete set
