This greatly depends on the type (model) of the breaker and the box it fits into. If you're talking about the usual household panel, the answer is two wires, one for each of the two 120 volt phases. Not so long ago, such a breaker would've had two handles linked together, obviously two circuits. These days dual phase breakers commonly have a single handle. If you examine the set-up, you'll find two contacts on the bottom of the breaker that fit onto two contacts inside the box. This is where two phases of power is applied to the breaker. On the side of the breaker you'll see two wire terminals. This is for the two wires which connect to the load.
If you're the guy who asked about reversing a three phase motor, I fear we may be miscommunicating. Three phase power in the USA is commonly called 220 VAC and two phase is called 240VAC. Did you really mean what you said? If you're not certain that what I described above exactly matches your situation, please contact me via answers email (look under my avatar). I'll be here for about three more hours and I'd be happy to answer your electrical questions.

4 -- 2 going into and 2 going out of the breaker.

In the home, generally two. Each one 120v from neutral. In an industrial place, it could be three.

depends upon the no of phases u have, normally two and three wires.
