Automatic circuit breakers | Choosing the Right Circuit Breaker
Electronic devices incorporate an automatically operated switch that acts in response to feedback from the load.  The switch will be triggered by a series resistor that will detect any excess current that in turn will cause a corresponding decrease in voltage across the resistor.  The advantage offered by such devices is that they react almost instantaneously because their operation is based on current sensing rather than much slower thermal expansion.
