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 digi-
tal inputs is assigned to thermal reset. This may be useful information when troubleshooting. When either of these counters
reaches 50000, that counter will reset to 0. Each counter can also be cleared using the
setpoint. The number of breaker operations will not update if a digital input programmed as Test
