Peak voltage across the varistor with a specified
peak impulse current of 8x20μs waveform.
The max. current within the varistor voltage
change of less than
±10%
when one impulse
current (8x20μs) applied.
The max. energy absorbed with a varistor voltage
change of less than
±10%
when one impulse
(10x1000μs) is applied.
