The 3ABD00059328-D: The ABB ACQ531-04-820A-4 is a 3-phase drive in Frame R11, rated 450 kW normal-duty output with 820 A continuous current at 380-480 V input. The light-overload rating sits at 810 A, also 450 kW — meaning this frame is sized for the full normal-duty current without headroom for heavy overload cycles; if your load profile demands sustained 110% for 60 s, check the light-overload curve against your actual motor current. Efficiency class IE2 means it meets the base EU MEPS level for this power band — not premium, but compliant for most industrial installations where the drive is not the sole efficiency driver in the system. IP00 open-type enclosure means it is intended for cabinet mounting with forced ventilation; no washdown or dust protection on the power stage, so plan for filtered airflow and a clean environment inside the panel.

Product details
Frequently asked questions
What frame size is this drive?
Frame R11. This is the physical mounting footprint and mechanical envelope for the 820 A output stage — verify cabinet cutout and bus bar spacing against the R11 dimensional drawing before panel layout.
What input frequency range does it accept?
47.5 to 63 Hz, covering both 50 Hz and 60 Hz mains worldwide without derating.
What is the closest alternative in the same family?
Within the ACQ531 series, the next step down is the 650 A frame (R10) at roughly 355 kW normal duty. The R11 is the 820 A variant; there is no pin-compatible drop-in — frame size changes the bus bar layout and control board mounting. If you need a second source, the ACS880-04 series offers similar power in a comparable frame but with different fieldbus option slots and a different safe-torque-off implementation.
