∗ Instantaneous or integrating reset is selected on the Inverse Overcurrent setup screen in
BESTCOMSPlus®.
† Constant A is variable for the 46 curve and is determined, as necessary, based on system full-load
current setting, minimum pickup, and K factor settings.
‡ Curve F has a fixed delay of one second times the Time Dial setting.
§ The programmable curve allows for four significant digits after the decimal place for every variable.
║ There is a minimum of 2 and maximum of 40 points that can be entered for any one T curve. For
information on setting T curves, refer to the Inverse Overcurrent (51) Protection chapter.
Time Overcurrent Characteristic Curve Graphs
The figures after the tables illustrate the characteristic curves of the BE1-11g. Table 252 cross-references
each curve to existing electromechanical relay characteristics. Equivalent time dial settings were
calculated at a value of five times pickup.
