ABB ACH480 Series - Electrical Power Network Specification; Motor Connection Data

If you use an external EMC filter, you must disconnect the internal EMC filter. Refer to
the electrical installation instructions.
Electrical power network specification
Input voltage range:
ACH480-04-xxxx-4 drives: 3-phase 380 … 480 V AC -15% … +10%.
Voltage (U1)
Public low voltage networks. Symmetrically grounded TN-S system, IT
(ungrounded), corner-grounded delta. Consult ABB before connecting
to other systems (for example, TT, or midpoint grounded delta).
Network type
65 kA when protected by fuses given in the fuse tables.Rated conditional
short-circuit current
(IEC 61800-5-1)
Note: If the short-circuit current is more than specified in the table below,
it is necessary to use a mains choke.
US and Canada: The drive is suitable for use on a circuit capable of de-
livering not more than 100 kA symmetrical amperes (rms) at 480 V
maximum when protected by fuses given in the fuse table.
Short-circuit current
protection (UL 61800-
5-1, CSA C22.2
No. 274-13)
Note: If the short-circuit current is more than specified in the table below,
it is necessary to use a mains choke.
Use a mains choke if the short-circuit capacity of the network at the drive
terminals is more than in the table:
Mains choke

>10 kA>5.0 kA3-phase 380 … 480 V
You can use one choke for several drives if the short-circuit capacity at
the drive terminals is reduced to the value in the table.
