Abstract:
1. An electronic fuse circuit for interrupting a current flowing through a power circuit, the electronic fuse circuit comprising: a trip switch structured to open to interrupt the current flowing through the power circuit and to close to permit the current to flow through the power circuit; a current sensing circuit structured to sense when a magnitude of the current flowing through the power circuit is greater than a predetermined magnitude; a trip circuit structured to control the trip switch to open in response to the current sensing circuit sensing that the magnitude of the current flowing through the power circuit is greater than the predetermined magnitude and to control the trip switch to close when the current sensing circuit does not sense that the magnitude of the current flowing through the power circuit is greater than the predetermined magnitude; and a processor having a routine, the routine being structured to monitor a characteristic of the trip circuit and, when the monitored characteristic meets a predetermined criteria, to enter an override mode, wherein, in the override mode, the processor is structured to output a signal to the trip circuit which forces the trip circuit to control the trip switch to open and remain open regardless of the magnitude of the current flowing through the power circuit.
