BLITZDUCTORconnect schützt Windkraftanlagen vor Überspannungsschäden
DEHN protects wind turbines


Easy. Safe. Robust.


Protects the sensitive systems of wind turbines
For maximum system availability

Protection of measuring and control systems in wind turbines, for example

  • Sensors for pitch systems
  • Control systems for aircraft warning lights
  • Sensors for the yaw system
  • Communication systems of the turbine controller
  • Measuring devices such as the wind sensor


Protection against failure caused by lightning strikes and surges

BLITZDUCTORconnect is an optimal protection solution for the various requirements of wind turbines.
The arrester is pluggable and can be remotely monitored.


BLITZDUCTORconnect: Quickly installed - safely monitored - easily maintained.


Your benefits

Ensure system availability, optimise staff capacities, gain space.

  • With BLITZDUCTORconnect you

    Ensure system availability
    The signal circuit is still available in case of arrester overload. This is particularly important for wind turbines.

    Optimise staff capacities
    Remote monitoring simplifies maintenance and reduces the time spent on servicing.

    Gain space
    Installation space in wind turbines is limited.
    The slim design of the arrester is of great benefit here.

  • DEHN protects off shore wind projects
    Signals are always available

    Systems remain available thanks to the fail-open function

    Reliable system availability is a top priority of wind turbines to ensure smooth power generation.
    The system must continue to operate even if an arrester fails due to surges and has to be replaced.

    The fail-open function disconnects overloaded protection modules from the signal circuit - The system remains functional.

    This ensures increased system availability.

    See the status at a glance

    Optimise staff capacities

    The mechanical status indication always provides a complete overview. Failure of individual arresters due to overload is immediately apparent through the red inspection window.
    The service engineer can see at a glance which arrester needs to be replaced.

    Your benefit: No further programming when installing or replacing an arrester, i.e. no further test equipment or training of service personnel.

  • BLITZDUCTORconnect schützt Windenergieanlagen
    Remote signalling unit monitors up to 50 arresters

    Easy arrester monitoring

    A compatible remote signalling unit makes it possible for you to report the status of the arresters directly to a higher-level monitoring system. Testing on site is no longer required since the arresters are permanently monitored.

    The active transmitter and receiver unit with passive reverse unit allows you to monitor up to 50 arresters.
    Your benefit: Testing on site is not necessary.

  • BLITZDUCTORconnect schützt Windenergieanlagen
    Easy maintenance thanks to secR module locking

    Compact or modular?

    The BLITZDUCTORconnect product family consists of compact and modular devices. All arrester variants have a width of only 6 mm.

    Modular arresters consist of a base part and protection module. The module locking mechanism fixes the protection module to the base part and is vibration and shock-tested.

    Your advantage in terms of maintenance: Only the overloaded module has to be replaced. This quickly restores the surge protection for the system without the need for rewiring.

Easy to install

Tips for installing BLITZDUCTORconnect


Reliable protection for measuring and control technology and process automation in industrial environments.


Secure against vibrations

BCO secR module locking

The surge protection modules stay put even in case of vibrations and shock.

Practical: The faulty arrester can be seen at a glance via the status indication. The module is released by means of two buttons.

This allows quick and easy replacement - without tools. The relevant module is removed, the adjacent modules remain locked in place.

Safe and easy maintenance

BCO signal interruption

Pulling the arrester module, turning it 180° and plugging it into the base part again interrupts the signal.

This ensures quick and easy measuring - without tools.


This saves time during maintenance.

Neu: PCB-Basisteil für BLITZDUCTORconnect

Jetzt bekommen Sie auch eine leiterplattenbasierte Systemlösung für den Schutz von MSR-Kreisen.

  • Damit sparen Sie Platz, denn das PCB-Basisteil wird direkt auf die Leiterplatte gelötet.
  • Damit vereinfachen Sie die Wartung, denn jedes einzelne Basisteil ist fernüberwacht.


Praktisch: Die steckbaren Schutzmodule tauschen Sie ganz einfach werkzeuglos. Wie bei allen BLITZDUCTORconnect-Varianten.
