    LEDs to indicate the type of overcurrent trip. The Fast-Curve LED indicates a Fast-Curve Trip. Recloser/Breaker Wear Monitor The M-7679 control records the amount of current carried in each phase each time the recloser trips. The control’s operational logic employs an algorithm integrating the amount of unfiltered AC current at the time of each trip and the number of operations (close to open) as a method of calculating wear.
