Peak voltage across the varistor with a specified
peak impulse current of
8× 20μs waveform.
Maximum 50〜60Hz power which may be
loaded for 1,000 hrs at 85± 2℃ with
△VCmA/ VCmA ≦± 10%.
The max. current within the varistor voltage
change of less than ± 10% when one impulse
current (8× 20μs) applied.
The max. current with a varistor voltage change
of less than ± 10% when two times impulse
current (8× 20μs) are applied at intervals of 5
minutes.
The max. energy absorbed with a varistor voltage
change of less than ± 10% when one impulse(10
× 1000μs) is applied.
The max. current with a varistor voltage change
of less than ± 10% when 10,000 times impulse
current (8× 20μs) are applied at intervals of 20
seconds at room temperature.
