Interesting I guess. You can hardly buy a CT for that, but a couple of comments:
I have some pzct-02 CTs and have tested them. They saturate at about 50A at 60Hz. They state 100A so maybe they have beefed them up? (doubt it).
The device connects directly to the wall AC. I’m guessing there is no UL or CE on this.
All that said, there is a market for everything.
