The horizontal axis is the impulse time that is the width of the surge waveform, the vertical axis is the peak value of the impulse current, and the number on the line is the number of impulses.
Maximum surge current imax = f(tr,pulse train)
A=Leakage current,
B = Protection level for worst-case varistor tolerances
