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(2ms) is applied.

Capacitance shall be measured at 1 kHz± 10%,1
