The input current is affected by the supply voltage and impedance.
Typical input current
The values of typical input current are given to aid calculations for power
flow and power loss.
The values of typical input current are stated for a balanced supply.
Maximum continuous input current
The values of maximum continuous input current are given to aid the
selection of cables and fuses. These values are stated for the worst case
condition with the unusual combination of stiff supply with bad balance.
The value stated for the maximum continuous input current would only
be seen in one of the input phases. The current in the other two phases
would be significantly lower.
The values of maximum input current are stated for a supply with a 2%
negative phase-sequence imbalance and rated at the supply fault
current given in Table 6-14.

currents

Fuse ratings are for a DC supply or paralleled DC bus arrangements. When supplied by a single SPMC or SPMU of the correct rating, the AC input
fuses provide protection for the drive and no DC fuse is required.
