Pat, unless I'm misunderstanding your meaning, I think we might be talking apples, oranges, and bananas here on the time delay. The other mention above was for a slow trip time Airpax with the number 2 in the second part of the model number ( PP11 - 2 - **** ).
There's also the "fast" delay option ( PP11 - 1 - **** ) with a trip curve that sounds like what you could be describing.
If you look closely at the picture in the original post, its a PP11 - 0 - 10.0 - OB - V which is the instant fruit (I mean delay) 
. The - 0 = "instant" PN designation Airpax breaker is supposed to disconnect the load in less than 0.001 second ( 1 millisecond ) if current flow to the load rises above its rating.
Do you think the ones you were using might have been the ( PP11 - 1 - **** ) "fast" that has a curve like this?
