Electrical power network specification
ACS480-04-xxxx-4 drives: Input voltage range 3-phase 380…480 V AC +10%…-
15 %. This is indicated in the type designation label as typical input voltage levels
3-phase 400/480 V AC. Voltage (U1)
Public low voltage networks. Symmetrically grounded TN-S system, IT (ungrounded),
corner-grounded delta. Consult ABB before connecting to other systems (eg, 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 ne-
cessary to use a mains choke.
US and Canada: The drive is suitable for use on a circuit capable of delivering not
more than 100 kA symmetrical amperes (rms) at 480 V maximum when protected
by fuses given in the fuse table. Short-circuit current pro-
tection
(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 ne-
cessary 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
R3, R4 R1, R2 Frame / Voltage rating
>10 kA >5.0 kA 3-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.
