My previous statement was, in effect, you choose the wire size by the current draw of the load (motor, etc.) and then you choose the breaker by the wire size.
Breakers (and fuses) do not limit current. they open the circuit when the bimetallic surfaces get too hot. In the case of auto-resetting breakers they then close the circuit when the bimetallic surfaces cool.
Again, size the breaker (or fuse) for the wires connected to it.
