DEHNshield with remote signaling contact

Lives up to what other arresters promise!

Protection of terminal equipment with wave breaker function: The lightning impulse is reduced to a minimum so that there is hardly any energetic stress on terminal equipment. DEHNshield ... (FM) takes up only 4 standard DIN modules and is thus ideally suited for DIN rails where the available space is limited.

The combined arrester is available with remote signaling contact and can thus be monitored through your factory master control system. This ensures that faults are identified at an early stage and promptly eliminated.

Fields of application

DEHNshield ... (FM) is an optimal protection solution for residential buildings. Additionally, it is also recommended for special applications such as:

  • Connection of outdoor lights
  • Protection of charging stations for electric vehicles
  • Protection of gutter heating systems
  • Protection of inverters in certain constellations (for more detailed information, please see our brochure Application-optimised DEHNshield - Combined Arrester in the box on the right).

Installation upstream of the meter

DEHNshield ... (FM) meets the German VDN directive and can thus be installed directly upstream of the meter – A major advantage over comparable type 1 varistor-based arresters.

  All benefits at a glance:

  • Takes up little space – only 4 standard DIN modules required
  • Easy installation thanks to series connection by means of STAK 25 terminal
  • Wave breaker function inside – no negative interaction with the electrical installation
  • Easy monitoring via floating remote signaling contact
  • Can be installed upstream of the meter (in Germany)


We recommend using DEHNventil combined arresters for applications in industrial environments or in case of increased technical requirements.
