Figure 46 - Time-Current Characteristics for Trip Classes 5, 10, 20, and 30
For trip class time-current characteristics other than 5, 10, 20, or 30, scale the
Class 10 trip time according to the following table:
Table 165 - Time-Current Characteristic Scaling Factors
Automatic/Manual Reset
Overload Reset Mode (Parameter 173) allows you to select the reset mode for the
E300 Electronic Overload Relay after an overload or thermistor (PTC) trip. If an
overload trip occurs and automatic reset mode is selected, the E300 Electronic
Overload Relay automatically resets when the value stored in % Thermal
Capacity Utilized (Parameter 1) falls below the value stored in Overload Reset
Level (Parameter 174). If manual reset mode is selected, the E300 Overload
