Does SqD make a triple tapping breaker? Didn’t think so
Yes! But that ain’t it.
Hmm, neat. Haven’t run into that yet
And you won’t either… In residential
That is a breaker for a 3 phase panel.
I’ve seen them in residential panels.

Seller was a welder…
I Have occasionally seen 3 phase service in larger, older homes because it was once needed for residential A/C systems of certain sizes. Most of the time 3 phase is no longer needed, but not worth the effort to change.
