DEHNshield with remote signalling 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 signalling 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 signalling contact
  • Can be installed upstream of the meter (in Germany)

Note

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

Technical details

DEHNventil M combined lightning current and surge arrester Type 1 + Type 2

Multipole DEHNventil modular type 1 and type 2 according to EN 61643-11 spark-gap-based combined lightning current and surge arrester consisting of a base part and pluggable protection modules. Maximum availability due to RADAX Flow follow current limitation. Capable of protecting terminal equipment. For protecting low-voltage consumer´s installations against surges and even direct lightning strikes. For installation in conformity with the lightning protection zone concept at the boundaries from 0A – 2.

Appl.-opt. combined arrester DEHNshield type 1+2 for three-phase TN-S systems

Application-optimised multipole type 1 and type 2 DEHNshield spark-gap-based combined lightning current and surge arrester (according to EN 61643-11). Compact design due to space-saving spark gap technology with a width of only 1 module / pole. For use in residential buildings and special applications. Capable of protecting terminal equipment. For protecting low-voltage consumer installations against surges, even in case of direct lightning strikes. For installation in conformity with the lightning protection zone concept at the boundaries from 0A – 2.
