Amp•Seconds accumulate when current is equal to or greater than the
Rated Current
Amp•Seconds reset to 0 when current is less than Rated Current
Example:
Overcurrent Level = 160 160 160 Amps
Rated Current = 144 144 144 Amps
Overcurrent Delay = 1.0 10.0 20.0 Seconds
Overcurrent Time = 16 160 320 Amp•Seconds
Using Figures 3-21, 3-22, and 3-23 will help you determine where the
Overcurrent Level and Overcurrent Delay should be set for any application.

If the Overcurrent Alarm is set for DISABLED, the Overcurrent Level and
Overcurrent Delay will have no effect.
