    OBV5-B60 series

    Class B+C surge protection devices (Type I+II Surge Protectors) are designed by combining Class B (10/350us) and Class C (8/20μs) lightning and switching surge to be used in the equipotential connection of LPZ 0 and LPZ 2 zone.


    Class B+C surge protector is perfect for any kind of building being it residential, commercial, industrial and so on, these devices work as a complete protection device. In addition to this, you can also install transient voltage surge suppressor in those buildings, which get power via an overhead line resulting direct or partial lightning currents.


    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
