    OBV5-B60 series

    Type 1+2 tested (BS EN 61643) surge protector for use primarily on mains power distribution systems to protect connected equipment from transient overvoltages


    Designed for use at the boundaries of LPZ 0a to LPZ 2 as part of a co-ordinated SPD system, this type of protection is usually used for equipotential bonding in structures that have a Lightning Protection System (LPS) fitted, at the point cables enter the structure (LPZ 0a or b to LPZ1 boundary).


    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
