    OBV5-B60 series

    Universal varistor-based plug-in lightning/surge arrester for 3-phase power supply networks with separate N and PE (5-conductor system: L1, L2, L3, N, PE).


    The combination lightning current and surge arrestors OBV5-B60 meet the type 1+2 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 use of high-performance varistors permits a rapid response time and a low protection level, without any line follow current. If circumstances are uncertain and there is a risk of fire from an overload, the internal cut-off unit disconnects the arrestor from the mains if necessary.


    + Connectable lightning current and surge arrestors
    + High arresting capacity up to 50 kA (10/350μs)
    + Visual status display
    + Available with optional remote signalling
    + Vibration-proof
    + Combination arrestors for buildings with lightning protection
    + Simple standard hat rail mounting
    + Labelled connections
    + Usable in systems with lightning protection class 3+4
