I am installing a hot-tub, the documentation says it draws 46 amps on 4-wire 240 VAC. I know that a 50 amp GFI is perfect for the job. I also know that since its 240 I need a double throw breaker. When I ebayed a 50-amp double throw, I saw a double breaker with each half labled at 50 amps. It would seem to me that I was looking at a 100 amp breaker. Do I need a 25-amp double throw? Bascally, are double throws rated at the total current they draw, or at the current they draw through each leg?

You clearly don't have enough knowledge of electrical wiring to be doing this yourself. Before you kill yourself or someone else, get a licensed electrician to do this work. Hot tubs have similar rules as pools, and there are many more rules to follow that any documentation with your rub will have. Water and electricity make it more dangerous than other wiring.

Double Pole Gfci Breaker

What you are describing is a double pole 50 amp breaker. It will have the ability to break both legs of a 50 circuit simultaneously. Some manufactures make 50 amp single pole breakers that can be used in tandem as a double pole by the use of a yoke or connecting the handles together with a handle tie (or a stiff wire), even so you still have a 50 amp breaker.
A 50 amp gfci breaker will be terribly expensive if you find one.
A hot tub dealer might be able to supply you with properly equipped gfci pigtail.

How do you calculate you need a 50 amp breaker? Capacity should never be rated over 80%, 80% of 50 is 44, so that 50 amp breaker is real tight. I would suggest a 60 amp double pole breaker. And yes each half is rated 60, Not 120.

You need a double pole SINGLE throw breaker . Remember when you get confused always go back to the basics.
The basics:
You have a 46 amp/ 240 VAC circuit using 4 wires;
1 wire is neutral
1 wire is ground
2 wires are hot
Since you are carrying 46 amps on 2 wires , then each wire is carrying 23 amps @ 120 VAC you can use # 10 wire
A fault in a double pole single throw breaker will result in both legs tripping as one- the circuit is de-energized
a fault in 2 single breakers - will result in one of the legs still energized- not exactly a good thing to have in a wet environment.
What does the manufacturer recommend for breaker size & type ?
Be careful out there and if your not 100% sure call an electrician
BTW 46 amps is 92% of 50 Amps, you may want to go for a 60 amp DPST breaker

20 Amp Double Pole Gfci Breaker

Listen to Mr. Danger. He really is right. A 60 Amp double pole GFCI breaker is what I would put in. Make sure it is GFCI!! Why 60 Amps? When the pumps and heater kick on, the amps can spike over 50 which would trip the breaker and have you scratching your head. And forget the ebay breakers. These things are whats keeping your butt from 220v sitting in a warm tub right?? Find an electrical supply house, or Lowes or something, and tell them you need "a 60 Amp double pole G F C I circuit breaker" and tell them the brand of circuit panel you are putting it in. You're saving on a electricians bill, and this is one thing not to bargain for. When making final connections, the white wire(neutral)to the hot tub will originate from a unique terminal on the breaker itself(the unit you are buying). NOT the neutral bar in the panel. Ask the folks when you buy the unit to show you this spot. If at first it trips when you turn it on, I bet you didn't use my expertise.
Good luck!

As has already been said, you require a "Double Pole" breaker, but also check if you also require an RCD?
