    EN 61643-11

    Key Features and Benefits

    STP T12 12.5 is the series of combined Type 1+2/Class I+II devices for discharging lightning currents and protecting against voltage surges, in accordance with EN/IEC 61643-11. Suitable as the first step of protection in incoming power supply panels and areas with exposure to the atmosphere, where installations are usually provided with an external lightning protection system.

    Lightning impulse current (10/350μs): 12.5kA per phase
    Maximum discharge current (8/20μs): 50kA per phase
    Nominal discharge current (8/20μs): 20kA per phase
    TNS, TNC, TT and IT networks
    Un(L-N/L-L): 60V, 120/208V, 230/400V, 277/480V and 400/690V
    DIN-rail mountable, plug-in format
    Visual and remote end of life indicators
    Reversible chassis to allow cable entry from above or below
    Mechanically coded cartridges to avoid cartridge replacement errors
    Back-up fuse: 200 A gG
