Figure 550: Example of how the inverse time characteristic is leveled out with
currents over 50 x In and the Setting Pickup value setting “2.5 x In”. (the
IDMT Sat point setting is set to maximum and the Minimum trip time
setting is set to minimum).
The grey zone in Figure 550 shows the behavior of the curve in case the measured current
is outside the guaranteed measuring range. Also, the maximum measured current of 50 x
In gives the leveling-out point 50/2.5 = 20 x I/I>.
