The measurement shall be made as fast as possible to avoid heat affection. Maximum Allowable Voltage The 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 standard impulse current (8/20 s). Rated Power The maximum power that can be applied within the specified ambient temperature. Energy The maximum energy within the varistor voltage change of 10 % when one impulse of 2 ms is applied. Electrical Characteristics Environmental Mechanical Maximum Peak Current 2 times The maximum current within the varistor voltage change of 10 % with the standard impulse current (8/20 s) applied two times with an interval of 5 minutes. 1 time The maximum current within the varistor voltage change of 10 % with the standard impulse current (8/20 s) applied one time.
