I thought this was a nifty circuit at first.

I would be using one of these on the output side of a 7805 power supply at .6 amps and one on the output side of a 7824 power supply at 1.6 amps. The problem is that resistor RS would have to quite a large wattage rating in both cases. The 7805 power supply will be supplying an arduino controller, 4n25 optocouplers and ms2222a transistors and the 7824 will be supplying external I/O components. I just thought this would be nifty instead of traditional fusing. Can anyone recomend a fusing circuit or small device other the the good old glass fuse?
