What are the instantaneous trip dial settings on thermal magnetic breakers?

Issue:
What are the trip settings between minimum and maximum on a thermal magnetic circuit breaker instantaneous trip adjustment dial or slide bar?

Product Line:
Circuit Breakers

Environment:
Thermal magnetic breakers frame size 250A and above

Resolution:
Turning the dial adjusts the magnet air gap and armature spring tension.  
For all practical purposes the trip setting change from minimum to maximum is linear between the two end points with a tolerance of -20% /+30% and we do not publish discrete values for each tick mark on the dial.
