Maximum Allowable Voltage The recommended maximum sine wave voltage (RMS) or the Maximum DC voltage can be applied continuously. The maximum voltage between two terminals with the specification standard impulse current. Applied waveform: 8/20μs Maximum Clamping Voltage To meet the Specified value Rated Wattage The maximum average 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 10/1000μs or 2ms is applied. Withstanding Surge Current The maximum current within the varistor voltage change of ±10% with the standard impulse current (8/20μs) applied one time. The change of Vb shall be measured after the impulse listed below which is applied 10,000 times continuously with the interval of ten seconds at room temperature. 5Φ series 7Φ series Surge Life 10Φ series 14Φ series 20Φ series Circuit Protection System 180K to 680K 10A (8/20μs) 820K to 751K 20A (8/20μs) 180K to 680K 25A (8/20μs) 820K to821K 50A (8/20μs) 180K to 680K 50A (8/20μs) 820K to 112K 100A (8/20μs) 180K to 680K 75A (8/20μs) 820K to 182K 150A (8/20μs) 180K to 680K 100A (8/20μs) 820K to 182K 200A (8/20μs) ∆Vb ±10% Vb ≤ Revision:DEC-16 Please refer to http://www.ruilon.com.cn for current information.
