Is ImportLimitCur a per phase setting or a sum of 3 phases on H3-10.0-Smart?

Hi,
I have 3 phases power with 80A fuse on each phase. But the main switch is 35A.

I want to work out how large I can set the value of ImportLimitCur on H3-10.0-smart inverter, as I have EV wall charger, hot water(6kw) and other 5kw usage at the same time, together with the battery charging during the 3 free hours.

So here comes to the question:
Is ImportLimitCur a per phase limit or sum of 3 phases limit?

It’s a good question, this is a total limit of all 3 phases summed.

Thank you very much Dave for the confirmation!
(This should be written in the manual as well. )

Then I have peace in mind to increase it to 90 A, leaving 15 A buffer.
