One of the 489 general counters will count the number of breaker operations over time.
This may be useful information for breaker maintenance. The number of breaker
operations is incremented whenever the breaker status changes from closed to open and
all phase currents are zero. Another counter counts the number of thermal resets if one of
the assignable digital inputs is assigned to thermal reset. This may be useful information
when troubleshooting. When either of these counters exceeds 50000, that counter will
reset to 0.
