DESCRIPTION OF PRODUCTS 
 EL1-25 series graphite gap Surge Protection Device(Belongs to thefirst class lightning protection, 10/350us waveform) are designed according to IEC and GB standards.Suitable for grounding systems IT,TT, TS, TN-N-S.It used for power level I surge protection in equipment systems

      at high risk of lightning strikes.It can prevent all kinds of surge currentincluding direct lightning, and can be applied to single-phase and three-phase generation lines through different number of combinations,

      modular design, standard 35mm guide rail installation method, installedin the building's main distribution cabinet (box) and outdoor distribution

      cabinet (box), with high lightning discharge capacity, no continuous current,The maximum impulse current (10/350 ps) of a single module can reach limp=12.5KA, limp=15KA, limp=25KA, limp=35KA, limp=50KA, and the maximumdischarge current (8/20us) can reach Imax=100KA, Imax=120KA, Imax=150KA,Imax=160KA, Imax=200KA.
