Protection Module for DEHNventil® modular
Spark-Gap-Based Protection Module
- 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

Details
The spark-gap-based protection modules of the modular DEHNventil series combine safety and innovation in a single device. Apart from the encapsulated RADAX Flow spark gap technology, the compact protection 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.
Avoid additional, short-notice and unplanned maintenance jobs.
In multipole protective circuits, we recommend replacing the complete set of protection modules when one module fails.
