Yes, I’m sure. I used to have 5MJ ones, but one burned down once. So I got the large ones. AFAIK, they are the largest that will fit 1 unity in a DIM panel. It’s supposed to change phases more than once if it receives that kind of abuse, but keep safely conducting electricity all the way.
It’s a common component around lightning protection. You’d want something better to actually deal with the lightning if your network is unprotected (there are plenty of options), but mine is protected.
That’s 21 kilowatt hours worth of energy, are you sure about that?
