)
500 V units: 380…500 V AC 3-phase ± 10%. This is indicated in the type designation
label as typical input voltage levels (3~ 400/480/500 V AC).
690 V units: 525…690 V AC 3-phase ± 10% (525…600 V AC ± 10% in UL/CSA
installations, or corner-grounded TN systems). This is indicated in the type desig-

For supply units with one R1i…R4i module: Short-circuit withstand
strength (IEC/EN 61439-1) Maximum allowable prospective shortcircuit current
I
cc
is 65 kA. In this case, the
input cable must be equipped with fuses as follows:
• maximum 10 A gG* for frame size R1i (basic module type ACS880-104-008A0)
• maximum 25 A gG* for frame size R2i (basic module type ACS880-104-0018A)
• maximum 50 A gG* for frame size R3i (basic module type ACS880-104-0035A)
• maximum 63 A gG* for frame size R3i (basic module type ACS880-104-0050A)
• maximum 125 A gG* for frame size R4i (basic module type ACS880-104-0035A)
*) Type gG according to IEC 60269
Maximum allowed operating time is <0.1 s for fuses mentioned above.
For supply units with one R6i module:
Maximum allowable prospective shortcircuit current I
cc
is 65 kA. In this case, the
input cable must be equipped with fuses as follows:
• maximum 400 A gG* for frame size R6i
*) Type gG according to IEC 60269
Maximum allowed operating time is <0.1 s for fuses mentioned above.
For supply units with R8i module(s):
Supply units with the ABB-defined main switch-disconnector and fuses:
• Rated peak withstand current I
pk
= 105 kA
• Rated short-time withstand current I
cw
= 50 kA/1 s
Supply units with ABB-defined main breaker and fuses:
• Rated peak withstand current I
pk
= 143 kA
• Rated short-time withstand current I
cw
= 65 kA/1 s
The drive is suitable for use on a circuit capable of delivering not more than
100,000 rms symmetrical amperes at 600 V maximum when the input cable is
protected with class T fuses. Short-circuit current protec-
tion (UL 508A, CSA C22.2
