Time to Trip
When the measured motor current exceeds the trip rating of the E300 relay,
Overload Time to Trip (Parameter 2) indicates the estimated time remaining
before an overload trip occurs. When the measured current is below the trip
rating, the Overload Time to Trip value is reported as 9,999 seconds.
Table 421 - Overload Time to Trip (Parameter 2)
Time To Reset
After an overload trip, the E300 relay reports the time remaining until the device
can be reset through Overload Time to Reset (Parameter 3). When the %
Thermal Capacity Utilized value falls to or below the Overload Reset Level
(Parameter 174), the Overload Time to Reset value indicates zero until the
overload trip is reset. After an overload trip is reset, the Overload Time to Reset
value is reported as 0 seconds.
