Most of the breakers in a panel will be 120 VAC. Double height breakers are 240 VAC. A triple height breaker probably indicates you have 3-phase power in the panel.
You need a breaker rated for 10 amps and 250 volts. The breaker must also fit properly in your panel.
Before energizing a breaker for a circuit, the circuit has to be clear of any short circuits or grounds. This can be accomplished by the use of a megger on the correct voltage setting.
Yes, you can always have heavier wire than code requires.
Two pole what? Switch, breaker? 2 pole does just that. Either switches two separate sources like different legs of a 220 volt circuit or switches both the hot and neutral in a 120 volt circuit or plus and minus in a 12 volt circuit or a two pole breaker takes 2 separate 120v legs in a home breaker panel. Each leg of 120 volt breaker panel is 120 volts to ground and 240 volts between them. The electricity entering your house looks like a sine wave with each leg being 180 degrees out of phase from the other. The double pole breaker takes each separate leg to the device it is powering and provides 240 volts.
The load exceeds the limit of the breaker or fuse. For example a 20 amp breaker on a 120 volt circuit will handle 2400 watts. Exceed that wattage and the breaker will trip or the fuse will blow.
On most residential circuit breaker boxes in North America, each individual breaker represents one 120-volt circuit. Two breakers ganged together represent a 240-volt circuit.

Sounds like a 240 volt sub panel feeding a well pump.

In North America you can not obtain 230 volts from just one single pole breaker. The distribution is like this, from a one pole breaker to neutral is 120 volts. From an adjacent breaker to neutral is 120 volts. From the adjacent breaker to adjacent breaker (breakers situated beside each other) the voltage will be 230 volts.If you want to incorporate a 120 to 230 volt transformer into the circuit you can obtain 230 volts. The primary side of the transformer will be connected to the 120 volt circuit and the secondary side of the transformer will output 230 volts. The transformer must be sized to the load amperage or the load wattage of the connected 230 volt load.
No, a double pole 50 amp breaker protects a 240 volt supply at 50 amps. The number that is on the handle of the breaker is the amperage that the breaker will trip at if an overload occurs on the circuit.
Look for directions on the air-conditioning device and you will see how many amperes it spends. I believe that is 10 A on average.
A volt can not be connected to a circuit.
