The ABB 3AXD50000050477 is a cabinet-built LV AC drive for water and wastewater. It delivers 315 kW (585 A) in normal use, 250 kW (429 A) in heavy-duty use, and 315 kW (575 A) in light-overload use on a 380–480 V three-phase supply. The drive is rated for 405 kV·A apparent power output and operates at 47.5–63 Hz.
The heavy-duty rating (PhD 250 kW, IhD 429 A) applies for constant-torque loads such as conveyors or positive-displacement pumps, where the drive must deliver full torque across the speed range. The light-overload rating (PlD 315 kW, IlD 575 A) covers applications with occasional overload peaks, like screw pumps or aerators. The UL ratings mirror these: 350 Hp / 414 A heavy-duty, 450 Hp / 573 A light-overload.
Enclosure, mounting, and environment
Ambient temperature is limited to 40 °C maximum, with humidity from 5 to 95% RH. The drive is designed for cabinet mounting, so plan for adequate ventilation and clearance per the installation manual.
What's included and interfaces
The drive ships with the control unit included. It provides 2 analog inputs, 2 analog outputs, 6 digital inputs, and 3 digital outputs. Communication is via CAN; there are no onboard Industrial Ethernet interfaces. A lithium coin cell (CR2032, 220 mAh, 3 V) is fitted for backup. Sound pressure level is rated at 72 dB(A). Power consumption at rated load is 9471 W.
