Abstract:
An electronic fuse circuit for interrupting a current flowing through a power circuit includes: a trip switch structured to open and close to interrupt and permit, respectively, the current flowing 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 and close based on the sensed magnitude of the current flowing through the power circuit; and a processor having a routine structured to monitor a characteristic of the trip circuit and, when the monitored characteristic meets a predetermined criteria, to enter an override mode and control the trip circuit to control the trip switch to open regardless of the magnitude of the current flowing through the power circuit.
