Protection Module for DEHNsecure modular
• Spark gap technology particularly suited for use in d.c. circuits
• Operating state / fault indication by green / red indicator flag in the inspection
window
• Easy replacement of protection modules without tools due to module locking
system with module release button
DSE MOD ...: Spark-gap-based protection module

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.
For protecting d.c. consumer installations against surges
and even direct lightning strikes. For installation in con-
formity with the lightning protection zone concept at the
boundaries from 0A – 1.
