An article in wikipedia (http://en.wikipedia.org/wiki/Resettable_fuse) statesDevice Reset Time
Returning to Figure 4, we note that after a trip event, the resistance recovery to a quasi-stable value is very rapid, with most of the recovery occurring within the first one-to-two minutes.
In my first post a modified the conclusion a little:When the power and fault are removed, the PPTC device will cool. As the device cools, it regains its original crystalline structure and returns to a low resistance state where it can hold the current as specified for the device. This cooling usually takes a few seconds, though a tripped device will retain a slightly higher resistance for hours, slowly approaching the initial resistance value.
