This time its controlled by two PNP transistors, instead of a relay like my previous version. It's faster and more accurate, and I've included a potentiometer, so you can adjust the "trip current"; or make it Function as a short protection circuit, so that power is only cut-off from your circuit if an abnormal spike of high current is detected, such as a a short. Use the push button to activate/reset. *It's faster than the LED* Try to short out the resistor in series with the LED, and watch as it trips before the LED burns out!
