ABSTRACT:
A circuit breaker includes current detectors, a microprocessor-controlled tripping device, and a bypass circuit that interacts with a watchdog circuit that monitors the proper functioning of the microprocessor. A switchable reference voltage is made available to the bypass circuit as a function of the momentary supply voltage. During short circuits, the bypass circuit, immediately upon being switched on, responds to very high limit current values, whereas after the switch-on phase, it already responds at moderately high limit current values.
