Performance Characteristicsv (Type E) Characteristics Test Methods/Description Specifications Electrical Standard Test Condition Power times 1 time Electrical characteristics shall be measured at following conditions (Temperature: 5 to 35 C,Humidity: Max. 5 %) The voltage between two terminals with the specified measuring current CmA DC applied is called Vc or VCmA. The measurement shall be made as fast as possible to avoid heat affection. The maximum sinusoidal wave voltage (rms) or the maximum DC voltage that can be applied continuously. The maximum voltage between two terminals with the specified standard impulse current (/0 μs). The maximum power that can be applied within the specified ambient temperature. The maximum energy within the varistor voltage change of ± % when one impulse of ms is applied. The maximum current within the varistor voltage change of ± % with the standard impulse cur rent (/0 μs) applied two times with an interval of 5 minutes. The maximum current within the varistor voltage change of ± % with the standard impulse cur rent (/0 μs) applied one time. To meet the specifi ed value.
