    OBV7 series

    lightning current arrestors OBV7 meet the type 1 requirement class according to IEC 61643-11. These devices protect low-voltage consumer systems from overvoltages of all types and are available in single-pole to four-pole versions. The voltage-limiting, high-performance spark gaps provide several benefits. A short response time, a low protection level and high current leakage capability with long service life.


    + Connectable lightning current and surge arrestors
    + High arresting capacity up to 150 kA (8/20μs) per pole
    + Combination arrestors for buildings with lightning protection system
    + Simple standard hat rail mounting
    + Labelled connections
    + Usable in systems with lightning protection class 1-4
