Your question doesn't make much sense to this old electrician. Breakers are designed to interrupt the power to a device because of an overcurrent condition. A three pole breaker will interrupt all three legs if there is over draw on one, two, or three of the legs. If you are considering control circuits, you must be talking about relays or contactors which is a different sort of device for remote or automatic closing and opening of circuits.

As far as power you just wire the proper capacity breaker to every pole that is involved. If you also want to monitor whether a breaker is on or tripped you can have an auxiliary contact added that can be wired to a control system (only 1 contact needed since the breaker trips all poles on any fault in a pole)

Your mixing up power and control circuit. In power circuit 3 phases are connected to each pole of breaker ie. one phase to each pole, when breaker comes on or closes we get voltage at the output of breaker.
Control circuit is there for closing or tripping of the breaker.
control circuit voltage is at munch lower level ie 110v ac, 24v dc, 240v ac.
power side voltage can be at 415v, 3.3Kv, 11KV etc.
