Yes, strange.
Does this perhaps only have to do with the standard probes?
I mean 40V (x1) should actually result in 400V (x10).
100V/div should also be enough.

exactly 400V that's what I expected too. maybe the pcb has some problems dealing with signals above 40V on the input module. I'm not really expert in scope electronics it's just a guess.

Maybe it's not a physical limitation.

Maybe they just don't want people poking at industrial 3 phase supplies with these.

Yes, I think so too. Either that, or a typo.
The scope shouldn't care as long as the probe doesn't supply more than 40 volts at the BNC. The scale (max. V/div) is sufficient.

Fungus:
More likely just laziness by whoever wrote that.

Never equate to stupidity that which can adequately be explained by laziness and ignorance.
