Just wondering how to get breaker size off of this nameplate? Thanks!

From my many experiences with hot tubs, when you see 40A and 48A, that translates to 50A & 60A.

40 x 1.25 = 50
48 x 1.25 = 60

The reason they list both amperages is it depends on how much of the equipment is used such as more than one pump, heater, etc.
Most customers want the "full boat" and if that's what is in the tub you wire to the largest. Even if they don't have it they will want to add it later so if you wire it to the highest it will be ready when they decide to add the rest.

Alright so I will go with a 2 pole 60. Not much experience with hotubs. Thank you for the help!

I don't know if all manufacturers are this way, but some don't make a 60 amp GFCI that includes a neutral and it looks like some of the components are 120 volt.

You sometimes have to find a small 60A disconnect and a 60A GFCI feeder breaker from the main panel or find a 60A GFCI disconnect of another brand. Can't remember which brand has it but there are a couple that have a 60A GFCI. But you correct that some only go up to 50A.

I prefer to find a disconnect that has the GFCI breaker because you can usually buy the whole thing cheaper than you can buy just the GFCI breaker.

Example: Cutler-Hammer 50A Spa disc. w/50A GFCI breaker = 65.00
Cutler-Hammer 50A GFCI breaker only = 79.00
 
Everything was already hooked up before by whoever installed it. It was just removed from the panel because they needed the space. They had a panel change and can now put the hot tub back on a breaker but they do not know what size it was on before. So I am just trying to find out how to get the proper size breaker?

There are far more 50 amp units then 60 amp. Not sure I have ever installed a 60 amp tub. I don't question their existence but I had not come across one. Why would they make a 60 amp unit if the 60 amp gfci is hard to find.....Seems silly to do that

Square D QO comes in both 50 and 60 amp GFCI versions, the 50 has neutral and can run 120/240 volt circuits, the 60 doesn't have a neutral and can only run straight 240 volt loads.

It's like I stated above. It has to do with the loads for the tub.

I've installed several 60A tubs.

60A units usually have an extra jet pump, a larger heater, or can run the jet pumps on high, heater, and blower simultaneously, whereas 50A installs of the same units cant run everything at once. Many can run on 30A but only one jet pump on low and the heater cuts off when the spa is being used.

60A GFCI arent hard to find, tho not all have a place to land a load side neutral; those are designed for straight 240V loads.
 
Midwest was somehow part of same company as GE at one time, and they used to always come with factory installed GE breakers in their products. Seems lately they usually have Siemens breakers if factory installed. I think most if not all their products have and still do list nearly all 1 inch wide products out there as being acceptable in their products that accept a plug on breaker. GE, Siemens, Homeline, Eaton BR...maybe older models that were absorbed by one of those four.
