Additional Details:

The S07K680E2 varistor has a maximum allowable voltage of 680V. The 'E2' suffix denotes an epoxy coating, providing enhanced insulation. Varistors are voltage-dependent resistors that exhibit a highly non-linear current-voltage characteristic. When the voltage across the varistor exceeds its clamping voltage, the resistance of the varistor rapidly decreases, diverting the surge current away from the protected components. This helps to prevent damage caused by overvoltage conditions. For complete specifications, including surge current ratings, clamping voltages, and derating curves, refer to the official EPCOS (TDK) datasheet.
