TCC Clipping |
You can clip the time current curve (TCC) for the breaker at the specified current in kA for Momentary (1/2 cycle), 5-cycle or 30-cycle. Select <None> to avoid clipping of the TCC. |
|
SC Tick Marks |
Select the appropriate check boxes to display the tick mark on the TCC plot. You can display Momentary, Interrupting and 30 Cycle short circuit values. Enter the corresponding short circuit values in kA in their respective edit fields for phase short circuit. These settings are only used if User-Specified is selected in Coordination Options > General > Default TCC Short Circuit Currents. Otherwise, the values are automatically calculated. |
|
Default Phase SC Values |
The short circuit values entered in kA in these fields can be displayed for phase currents on TCC plots. These settings are only used if User-Specified is selected in Coordination Options > General > Default TCC Short Circuit Currents. Otherwise, the values are automatically calculated. |
