Measure values are example
Menu value I
In this menu option, all measured currents are displayed. If the
value is less than 18% of I n , display of the value is suppressed. The
characters o and ¤ will then appear alternately on the display.
value I aktL :
current in the highest-loaded phase
value I maxL :
maximum current which has flowed in the
last 15 minutes
value I minL :
minimum current which has flowed in the last
15 minutes
value I L1, L2, L3:
operating current in phases L1, L2, L3
