1 Maximum continuous working voltage MCOV/UC(VAC): The maximum continuous working voltage continuously applied to the SPD line end
2 Nominal discharge current (In) (kA): The measured value of SPD withstand capability; the measured value of 15 pulses using 8/20us current waveform.
3 Maximum discharge current (max) (kA):The maximum discharge current is the measured value of the SPD's maximum withstand capability, and the measured value of 2 pulses using 8/20us current waveform
4 Voltage protection level/Up: IEC61643-11 voltage protection level, the maximum residual voltage measured value of the nominal discharge current (ln) under continuous application of 8/20u pulses, is the maximum voltage measured value after one round
