As fast as possible, with no intentional delay.
The laws of physic pretty much prevent an activity from happening exactly instantaneously. Our industry uses this term to mean that the event is happening as fast as the mechanical operation can function.

Jim nailed it, IEEE definition is "No intentional delay"
So the actual clearing time is based on the speed of the breaker itself. Usually 3-8 cycles, depending on the breaker type.
