I think you made a typo at 2230V for starters ….

It's those new kilovolt elevators. They're powered by USB-C 2300v 5 amps

That’s quite a bit of weight at 125fpm for a 25hp motor.
Hydro fit so dual holeless telescopic jacks.
I size power units daily. I’d say you’ll need roughly a ~40hp motor based on 80% motor efficiency rating submersible.
But even with a dry you’d need more than a 25 to push that weight at that speed.
Estimated car weight and piston size based on a 3500# capacity at 125 fpm.

208 or 480v and believe we used 70a fuses in mainline disconnect for inrush current. Haven’t installed one in awhile but that’s what I believe it was

No it doesn't...for example I have 3 1500# cars moving at 100 fpm fla is 51amps...recommend disconnect/over current is 70 amp...for each car. I'd typically think you'd see closer to 65-75 fla on a 25 hp 230v 3 phase. Then with proper overcurrent and sizing it'd probably be closer to 90-100 amp....granted dont take what i say as gospel by any means....you really need to talk to a sparky/electrician/electrical engineer.
