Sizing a breaker for 10 HP RPC idler

I have this 10 HP 3 phase motor that I want to use as an idler.

This will be in a self starting capacitor start RPC. The motor will start without load.

My question is, how to properly size a circuit breaker for the 240V single phase circuit.

By the way, the subpanel in my garage is on a 60A breaker.

What is the size for the load motors you plan on running with this?

I would say, for a typical metalworking machine, up to 3 HP, and for a hypothetical 3 phase welder, up to the converter's capacity.

There will be an auction tomorrow with a dozen of used bridgeports and a Sharp mill on sale. Bridgeports are 1.5-2 HP and Sharp is 3 HP. All with DRO's. I will not bid on them now, but maybe one day.
