Does Schneider Electric SPD's have joule ratings?

Product Line: 
Surge Protective Devices (SPD's)

Resolution:
Joule ratings are not a recognized indication of protection and not an accurate rating of performance. In the surge protection industry the proper means of determining the protection level is the kA rating, Peak Current Rating (Maximum Current Rating) is the most current that the MOV device can handle without suffering irreversible damage.
