Purchased a GE Profile CookTop PP945 208/240. Service Panel has a 30 Amp Double Breaker wired for this Circuit. Will this Breaker/Voltage meets the requirements for this unit?

The owners manual will give u the amps and voltage needed. It may also be on a panel attached to bottom of cook top.

The voltage is going to be correct, but you have to worry about the amperage.
As Creahands said, read the manual.
