DEHNventil for Lightning & Surge Protection at Half the Size!

DEHNventil - the byword for powerful lightning current arresters since 1983 - now comes with its proven perfor­mance parameters in a new slim design.

The combined arrester, type 1 + 2 + 3, as per EN 61643-11, with a compact single module and remote signaling unit, now shows off its strengths in a compact size equivalent to 4x standard DIN modules.



The original in a new design

More space in the switchgear cabinet, and that means easier installation, spare space for future components or the option to choose a smaller cabinet.

DEHNventil scores with a follow current extinguishing capability of up to 100 kArms and an extremely low residual energy thanks to integrated RAC spark gap technology.

Advantages for you at a glance..

    • High grade glass filled black nylon polymer. Heat stabilized – suitable for120oC installations.
    • Low smoke and fume (LSF), UL94 V-0 classified, zero halogen and phosphorus free.
    • Very good mechanical and electrical properties.
    • Excellent UV performance.


Less Effort

    • High grade unreinforced nylon polymer. Low smoke and fume (LSF), UL94V-0 classified, zero halogen and phosphorus free.
    • Good mechanical and electrical properties.
    • Very good UV performance.


Maximum Protective Effect

    • Specially formulated polymer to comply with the stringent material performance requirements of the London Underground 1-085 standard,
      in relation to limited oxygen index, smoke density and toxicity.



More Space in the Switchgear Cabinet



More options

More space in the switchgear cabinet means more space for extra components.
On top of that, installation and wiring are much easier. 



In modern switchgear cabinets, space is increasingly at a premium. Whether it is energy meters or fire protection switches, space needs to be found for more and more components. With its compact design, DEHNventil creates more spare space here.

dehnventil-m2_ds377_en-19The small design opens up new oppor­tunities for optimally exploiting the available space. For example, lateral installation is also possible, which makes it easier to comply with the 0.5-metre cable length. 180°-rotated installations are also possible.
