Abstract
The present invention comprises a method for over-current protection. The method comprising monitoring a load current value of a load current passing through a plurality of micro-electromechanical switching system devices, determining if the monitored load current value varies from a predetermined load current value, and generating a fault signal in the event that the monitored load current value varies from the predetermined load current value. The method also comprises diverting the load current from the plurality of micro-electromechanical switching system devices in response to the fault signal and determining if the variance in the load current value was due to a true fault trip or a false nuisance trip.
