Strange specs for a toroidal transformer(?)

Correct. 0.86A

Oh Lee Crap! Is this amateur's half-hour?
It's using the same nomenclature as is used for resistors. \$103 = 1.0 \times 10^3\$, i.e. 1kVa. Which is congruent with its physical size!

For resistors its not 1.0, its 10 x 10^3 =10k

What is it, AA59902055?

...It's less likely to find standard parts among transformers, I mean customs are pretty common, but these ratings look standard enough. Might get lucky with a search :)
Don't see anything in there about primary VA though. Seems a strange way to mark it, if it's magnetization. If in doubt, I'd e-mail them.

Ironically, that datasheet has a typo on page 4 where the table lists powers from "425-800" "800-120" and "1200-1500"... perhaps the same engineer designed this transformer that wrote out that table!
