AFQm
The phase balancing option in AFQm-3WF-xxxx works in unbalances produced by loads
connected between phases in three-phase mains without neutral. The AFQm-3WF-xxxx
does not compensate unbalances produced by single-phase loads connected between
phase and neutral. Use a AFQm-4WF-xxxx to correct this type of unbalances.

Priority
Enable this option so that the device prioritises the functions in case of filter current saturation due to
overload:
With the function enabled , the current balancing between phases and the reactive current compensa-
tion is prioritised over the harmonic filtering.
With the function disabled , priority is given to the current harmonic filtering and power factor correc-
tion and overload balancing are penalised.
