Settings Sequence and Menus
※
1)
To enhance user convenience, time settings for certain features will not be displayed when certain protection features are deactivated.
2)
CT ratio setting (ctr) can be set to less than 2,000 A in conjunction with the rc setting.
3)
The menu indicates oc-t when overcurrent settings are set at definite time (dEF), and cLS when set to inverse time (thr, nthr)
4)
This feature is only available on the advanced type.
5)
Feature not offered for the instantaneous model.
6)
