[Ian Mcloughlin](https://news.demesne.ie/author/ian-mcloughlin) 10/13/2021 [0 Comments](https://news.demesne.ie/dehnventil-lightning-surge-protection#postComment) 1 Minutes 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.   ![Dehn-1](https://news.demesne.ie/hs-fs/hubfs/Dehn-1.png?width=431&name=Dehn-1.png) #### The original in a new design   ![dehn demesne Ad](https://news.demesne.ie/hs-fs/hubfs/dehn%20demesne%20Ad.png?width=1000&name=dehn%20demesne%20Ad.png)   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.. #### ![dehnventil-m2_ds377_en-6](https://news.demesne.ie/hs-fs/hubfs/dehnventil-m2_ds377_en-6.png?width=120&name=dehnventil-m2_ds377_en-6.png) More Space - - 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. ![dehnventil-m2_ds377_en-7](https://news.demesne.ie/hs-fs/hubfs/dehnventil-m2_ds377_en-7.png?width=120&name=dehnventil-m2_ds377_en-7.png) 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. ![dehnventil-m2_ds377_en-8](https://news.demesne.ie/hs-fs/hubfs/dehnventil-m2_ds377_en-8.png?width=120&name=dehnventil-m2_ds377_en-8.png) 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. ![dehnventil-m2_ds377_en](https://news.demesne.ie/hs-fs/hubfs/dehnventil-m2_ds377_en.png?width=2414&name=dehnventil-m2_ds377_en.png)   ## More Space in the Switchgear Cabinet #### ![dehnventil-m2_ds377](https://news.demesne.ie/hs-fs/hubfs/dehnventil-m2_ds377.png?width=666&name=dehnventil-m2_ds377.png) #### More options More space in the switchgear cabinet means more space for extra components. On top of that, installation and wiring are much easier.    ![dehnventil-m2_ds377_en-17](https://news.demesne.ie/hs-fs/hubfs/dehnventil-m2_ds377_en-17.png?width=230&name=dehnventil-m2_ds377_en-17.png) 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-18](https://news.demesne.ie/hs-fs/hubfs/dehnventil-m2_ds377_en-18.png?width=230&name=dehnventil-m2_ds377_en-18.png)More room in the switchgear cabinet means easy installation, when install­ing and wiring both the DEHNventil and adjacent components.       ![dehnventil-m2_ds377_en-19](https://news.demesne.ie/hs-fs/hubfs/dehnventil-m2_ds377_en-19.png?width=230&name=dehnventil-m2_ds377_en-19.png)The 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.     #### ![dehnventil-m2_ds377_n](https://news.demesne.ie/hs-fs/hubfs/dehnventil-m2_ds377_n.png?width=2414&name=dehnventil-m2_ds377_n.png)     ## Download Your DEHNventil Guide ### Click on the catalogue page below to go to the your DEHNventil product guide!
