    SMGU1-A15 Surge Protective Device

    Detailed introduction：

    Scope of application 

    SMGU1-A15 series of limited voltage surge protection device (belonging to a mine, 10 / 350μs waveform) according to IEC and GB standards.

    Applied to lightning risk areas of the higher power equipment, the first level surge protection system. It can be applied to single-phase, three-phase power supply lines, modularized design, standard 35mm rail-mounted installation, and installed in the main distribution cabinet (box) of the building through the combination of different quantities. ), Outdoor distribution cabinet (box), with high lightning current discharge capacity, no freewheeling, single module maximum impact current (1 0/350 μs) were up to limp = 15KA, limp = 25KA, limp = 35KA , Limp = 50KA maximum discharge current (8/20 μs) can be reached Imax = lOOKA, Imax = 1 50KA, Imax = 1 60KA, Imax = 200KA.
