Standard Test

Condition

Electrical measurements (initial/after tests) shall be conducted at

temperature of 5 to 35 °C, relative humidity of maximum 85 %

———

Varistor Voltage

The voltage between two terminals with the specified measuring

should be made as fast as possible to avoid heat effects.

To meet the

specified value.

Maximum Allowable

Voltage

The recommended maximum sinusoidal wave voltage (rms) or the

maximum DC voltage that can be applied continuously.

Clamping Voltage

The maximum voltage between two terminals with the specified

impulse current (8/20 μs).

Rated Power

The maximum power that can be applied within the specified

ambient temperature.

Maximum Energy

Maximum energy of less than ±10 % of the varistor voltage

change when the standard impulse (2 ms) is applied one time.

Maximum

Peak Current

Maximum current of less than ±10 % of the varistor voltage change

when impulse current (8/20 μs) is applied twice continuously with

an interval of 5 minutes.
