Does anybody know the model used. Or have done tests to determine at what current load the polyfuse starts kicking in?

I want to work out how much current I can draw via the GPIO power pins.

The recommended power supply is 5.1 volts and 2.5 amps for the Pi3. One assumes the polyfuse must have been increased to allow 2.5 amps to flow.

    There is now a Schematic for the Pi3 on the Foundation website which shows the fuse is MF-MSMF250/X
