The time delay is independent from the operating current flowing through the relay, so if the phase
current exceeds its predetermined value for an equal or greater amount of time than this preset value,
the protection function activates (trips) and does not reset itself until the average value of the phase
drops below the point of current pick-up.
The function activates at 100% of the preset input and deactivates at 95%. The reset is instantaneous.
The accuracy of the Time Delay is equal to the set time delay ±35ms or ±0.5% (whichever is greater).
OPERATING ANGLE = 90º
HALF-CONE ANGLE = 60º
