    33KV Surge Arrester


    33KV Surge Arrester Description


    SPD (Surge Protective Device or called surge arrester) is an appliance designed to protect electrical devices from voltage spikes. A surge protector attempts to regulate the voltage supplied to an electric device by either blocking or by shorting to ground voltages above a safe threshold. We have spark gap, MOV and Spark tube type for different protection area.

    For the whole building lighting protection, 30kA-60kA, 40kA-80kA, 50-100kA, are available, however, 30kA-60kA is the most common one. As we know, one building have two unita, one is A, the other one is B, for A or B, surge arrester 20/40kA will be your best selection. What's more, we also can provide the one such as surge arrester 5-10kA,especially 10-20kA to strongly protect the single room, 5-10kA to protect a single unit electric device.


    33KV Surge Arrester Features

    A high discharge capacity, low protection level and dual safety Thermo Dynamic Control disconnector define the high reliability of the devices.

    33KV Surge Arrester Applications

    - High discharge capacity thanks to powerful zinc oxide varistors
    - Quick response
    - Reliable control thanks to Thermo Dynamic Control disconnector with dual monitoring
    - Fault indication via red mark in the inspection window
    - Slim design (modular construction) according to DIN 43880
    - Multifunctional terminals for connection of conductors and busbars

    - Complete unit consisting of upper part and base, pre-mounted and ready for connection
    - Plug-in arrester with dynamic separating device
    - With visual function display
    - Enclosed, non-extinguishing zinc varistor arrester for use in normal commercial distributor housings

    Application example: building with an overhead power line supply or lightning protection system, for building up lightning protection equipotential bonding.

    Apart from the standard visual indication with green and red coloured marks, the variants of Greegoo.. BY series provide a 3-pole terminal for remote signalling. As the remote signalling contact works as a floating changeover contact, the remote signal can be used as a break or make contact, according to circuit concept.
