The ABB 3AXD50000050476 is an ACQ580-07-0505A-4 LV AC cabinet-built drive, purpose-configured for water and wastewater applications. It ships with the control unit included, so you are not sourcing a separate controller board for the cabinet build. Frame size R10, IP21 with NEMA Type 1 enclosure — rated for indoor installation where drips and falling dirt are the concern, not hose-down. Input accepts 380 to 480 V three-phase, 47.5 to 63 Hz. On the output side, normal-use rating is 250 kW at 505 A; heavy-duty use (constant torque) drops to 200 kW at 361 A. Light-overload use holds at 250 kW but pulls 485 A. UL ratings mirror the heavy-duty and light-overload currents at 361 A and 483 A respectively, with horsepower figures of 300 Hp and 400 Hp at 480 V. That 0.98 power factor keeps the upstream transformer and cabling sized closer to the real kW than the kVA.
The 505 A normal-use output current is the number to match against your motor FLA. If your load profile is variable torque (pumps, fans), the normal-use rating applies. The 72 dB(A) sound level is worth noting for noise-sensitive installations; it is not silent, but it is typical for a 250 kW cabinet drive in this frame class. Analog I/O is 2 inputs and 2 outputs, digital I/O is 6 inputs and 3 outputs. Communication is CAN — no onboard Industrial Ethernet, so if you need PROFINET or EtherNet/IP, plan for an optional fieldbus adapter module. The 8353 W power consumption at rated load is the heat to reject from the cabinet; factor that into your ventilation or air-conditioning budget. Operating humidity range is 5 to 95% RH, non-condensing. Maximum ambient temperature is 40 °C. The lithium coin cell (CR2032, 220 mAh, 3 V) backs up the real-time clock and parameter storage.
