    OBV10-I-25

    Type 1/Class I lightning current arresters, able to discharge energy (current) from a direct lightning strike (10/350µs) on an external lightning protection system (LPS) or overhead supplies, in accordance with EN/IEC 61643. Suitable as the first step of protection in incoming power supply panels and areas with high exposure to lightning strikes, fitted with an external lightning protection system.


    lightning current arrestors OBV10-I-25 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 25 kA (10/350μs) 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
