Snubber Circuits for Protecting Relay Contacts from Arcing
How to Select the Varistor Type To select a good varistor, first, you must make sure the cut-off voltage V C is multiplied with √2. Then, the value must be checked if it is more than 1.5 times the supply voltage. Keep in mind that setting the V C too high is not good as its efficiency will be reduced thus fails to cut off high voltages.
