Article 4.8.2.0 : Why 100A ACCL Trip with over Amp at 55A load?
Please find
the attached video on the same. As shown in video there is more than 99A current
shows in a An neutral. If it will cross more than 100 it will trip by Over Current Error.
What is neutral Current in the 3Phase system?
In a perfectly balanced 3 phase system, the neutral current will be zero.
This is because the neutral carries
the vector sum the currents in the other 3 phases which when balanced sum to
zero. In an unbalanced system, the neutral carries
the current imbalance.
