A-4 Time Overcurrent Characteristic Curves BE1-CDS220
In applications where the time coordination between curves is extremely close, we recommend that you
choose the optimal time dial setting by inspection of the coordination study. In applications where
coordination is tight, it is recommended that you retrofit your circuits with Basler Electric electronic relays
to ensure high timing accuracy.
