Peak voltage across the varistor with a specified peak impulse current of 8x 20s waveform. Maximum 5060Hz 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 (8x 20s) applied. The max. current with a varistor voltage change of less than 10% when two times impulse current (8x 20s) are applied at intervals of 5 minutes. The max. energy absorbed with a varistor voltage change of less than 10% when one impulse(10 x 1000s) is applied. The max. current with a varistor voltage change of less than 10% when 10,000 times impulse current (8x 20s) are applied at intervals of 20 seconds at room temperature.
