The Phase instantaneous overcurrent element has a setting range from 0.05 A to 160 A. It can be set as instantaneous or
timed, with the timer selectable between 0.00 and 900 seconds. The input quantities may be chosen as Fundamental
phasor magnitude or RMS magnitude as required by the application. The element incorporates a reset time selectable
between 0 and 900 seconds.
