I am planning out a mining setup that has power coming in at 415Y/240V . This is located in Missouri USA.
I was looking for breaker panels for this setup, but I only see 480Y/277V three phase panels being sold around here an online.

If the breaker can handle a higher voltage than the supplied voltage then that's fine, it's not like the breaker is going to increase the voltage from 240V to 277V, so all you need to worry about is the amp rating for those breakers, but again, as other people said, let the electrician write you the specs or let him source the panel himself.

Okay are you saying you have a 300kva three phase transformer?

You can not run 96 s19s.

3000 x 96 = 288,000 watts

Or 288 kwatts.

288/300 is greater than 80%

Actually, it is not just that, transformer rating is in VA which is not W unless the power factor is 1 which is not going to be the case for him, his PF is probably 0.75-0.8 (should be labeled on the transformer) so that would be a maximum of 225KW to 240KW, and he still got fans and other stuff to power on, I'd say anything above 70 S19s is pushing it.
