It depends upon the airline. We use 1500ft aal but my previous airline used 1000ft aal with the same aircraft type. It can be higher if terrain is an issue.
Note that climb thrust is not always less than take-off thrust. We often use less than full thrust for take-off to save engine life, yet we use full climb thrust to get to altitude quicker. Result is that sometimes at 1500ft the thrust levers go forward!!
