DEHN schützt die Bahn-Infrastruktur nach Ril 819.0808
DEHN protects the railway infrastructure


Protects signalling and control as well as telecommunication systems according the requirements of DB Guideline 819.0808.


Interlockings, level crossings, point heating systems and GSM-R transmitter and receiver systems ...
all components in the railway infrastructure require professional, long-term protection against lightning and surge damage.


The universal BLITZDUCTORconnect combined arrester is the optimal solution here.

Different product types and device variants fulfil the most diverse requirements in the railway environment. The modular version of BLITZDUCTORconnect is pluggable and can be remotely monitored.


  • For reliable operation of installations and systems.
  • For safe and punctual transport of people and goods.
  • For easy, practical maintenance.
  • For remote monitoring.

Easy. Safe. Ril compliant.

Reliably meet the requirements of Ril 819.0808 with BLITZDUCTORconnect.

1 - Narrow design
Two signal lines in a width of just 6 mm

2 - Release button
For connecting the signal line

3 - Measuring sockets
For easy maintenance

4 - Non-interacting
Signal availabilty even when an arrester fails

5 - secR technology
Safe removal of the module

6 - Push-in connection terminals
45° inclined, up to 2.5 mm2

7 - Disconnection function
Simple signal disconnection by plugging the module in the other way round

8 - Remote monitoring
Thanks to optional remote signalling transmitter and receiver unit

9 - LifeCheck indication
For visual status recognition

10 - Vibration and shock proof
For continuously safe operation

Your benefits

Ensure system availability, optimise employee capacities, gain space.

  • With BLITZDUCTORconnect

    Ensure system availability,
    signal circuit is also available in case of overload.

    Optimise employee capacities,
    thanks to remote monitoring,
    easy installation and initial start-up.

    Gain space,
    Two signal lines despite a width of just 6 mm solves space issues in your switchgear cabinet.

  • BLITZDUCTORconnect erleichtert die Wartung in der Bahninfrastruktur
    Optimising employee capacities

    Maintenance made easy

    How to optimise employee capacities

    A suitable remote signalling unit allows you to report the status of the arresters directly to a higher-level control system.
    The active transmitter and receiver unit including a passive reverse unit minimises the wiring effort during installation.

    The mechanical status display provides a complete overview at all times. Failure of individual arresters due to overload is immediately apparent in the red inspection window.

  • DEHN BLITZDUCTORconnect - FM-Einheit überwacht bis zu 50 Ableiter
    A SINGLE remote signalling unit monitors up to 50 arresters

    Monitoring of up to 50 arresters

    Innovative transmitter and receiver unit

    Particularly interesting for equipment suppliers in the railway sector:
    BLITZDUCTORconnect allows you to monitor up to 50 arresters by means of a single unit.
    Additional parameterisation of the arresters is not necessary.

  • DEHN hält Anlagen der Bahn am Laufen
    Keeping systems up and running

    Keeping systems up and running

    The fail-open fault mode keeps systems up and running

    Reliable system availability is a top priority for the smooth running of the railway infrastructure. After all, operations should continue even if an arrester has discharged surges and needs to be replaced. For example, level crossings must remain functional despite a failed arrester.

    The fail-open function disconnects overloaded protection modules from the signal circuit, this means railway systems remain operational - even if an arrester fails.

  • BLITZDUCTORconnect - Modultausch leicht gemacht.
    Easy maintenance with secR release mechanism

    Safe installation without tools

    This makes maintenance quick and easy

    Plug-in modules must be removed precisely. The secR release buttons prevent accidental removal of an adjacent module.

    Another advantage of secR: The module stays put - even in case of vibrations.

BLITZDUCTORconnect specifically for the railway infrastructure

The DB guideline Ril 819.0808 requires surge protection for all signalling and control systems.

BLITZDUCTORconnect meets all requirements in this area. With its simple remote monitoring, it optimally protects signalling and control systems in the railway environment.


This makes it easy for you to comply with the specifications and ensure the continuous availability of the systems.


Ril 819.0808 is relevant for everyone

  • signalling systems (electronic interlockings, relay interlockings, level crossings)
  • electric locally operated points (ELOP)
  • telecommunication systems (TC)


secR module locking mechanism

Vibration-proof and easy to service

The green/red status display clearly shows whether an arrester is faulty. Replacement is then quick and easy.

No tools and just two buttons are required to safely remove the module. Only the affected module is removed with no danger of accidentally releasing adjacent modules.

This is a major advantage when it comes to saving time during maintenance.

Another advantage of the secR locking mechanism:
It prevents the surge protection modules from working loose as a result of shock or vibration.
