Start current of the I> stage as a multiple of the rated current of the used energizing
input. Setting range 0.5...5.0 x In at definite time characteristic and 0.5…2.5 x In at
inverse time characteristic.
Note! Because of the maximum measured current (63 x In), the setting value 2.5 is
used for the IDMT calculation if the set value is greater than 2.5. This makes the
operate time faster than the theoretical IDMT curve. However, the stage always starts
according to the set value.
