The ABB 3AXD50000049030 is a control unit for the ACS880 drive family, frame size R10. It delivers 355 kW normal-use output at 650 A (light-overload 634 A, heavy-duty 477 A at 250 kW) from a 380–480 V three-phase supply, 47.5–63 Hz. The unit is IP00, open-type NEMA, and rated for a maximum 40 °C ambient at 1000 m altitude.
Key Ratings in Context
The normal-use output current (650 A) is the figure to size for continuous motor loads; the heavy-duty curve (477 A) governs applications with high starting torque or cyclic overloads. Apparent power rating is 450 kV·A at 0.98 power factor. Standby loss of 423 W and power consumption of 8046 W at rated load define the thermal budget for enclosure sizing. Sound level is 72 dB(A).
