1 There are three levels of protection in the UL rating -- 330 V, 400 V and 500 V. Generally, a clamping voltage more than 400 V is too high.  Energy absorption/dissipation - This rating, given in joules, tells you how much energy the surge protector can absorb before it fails. A higher number indicates greater protection. Look for a protector that is at least rated at 200 to 400 joules. For better protection, look for a rating of 600 joules or more.
Kilojoules to joules (kJ to J) conversion table shows the most common values for the quick reference. Alternatively, you may use the converter below to convert any other values. 1 Kilojoule (kJ) = 1000 Joules (J). Kilojoule is metric system energy unit (electrical, mechanical or thermal) and equals to 1000 times of the amount of work done by a force of one newton to move an object one meter.
