Art 440, Part II, Disconnecting means ( A-C equiptment)

440.12, Rating------ " ---- shall be selected on the basis of the name-plate rated-load current, or the Branch-Circuit "selected" current, which ever is greater."

I suggest you refer to the nameplate information which is required to appear on either the motor or the equiptment enclosure.

Good Luck & Enjoy the Experience!!!!!!!!!!!!!11

If you use a nonfused disconnect most of them are rated max 60 amps. If you use a fused one then same as breaker with info from faceplate.
