ABB ACQ580-01-039A-4 Water Drive 18.5 kW 38 A

Using the ACQ580-01-039A-4 on a pump station

ACQ580-01-039A-4 is a wall-mounted ABB ACQ580 drive designed for water and wastewater pumping. The catalogue rates it at 18.5 kW and 38 A in no-overload use on a 400 V network and builds it on frame R3. ABB describes the family for treatment plants, pumping stations, desalination plants, industrial wastewater facilities and irrigation, driving inflow, transfer, dosing, sludge, booster and submersible pumps as well as blowers, mixers and decanter centrifuges. The 18.5 kW rating sits in frame R3 and is typical for medium booster stations.

Typical functions in the ACQ580 pump control program are sensorless flow and head calculation, flow and pressure protection against dry running, resonance monitoring and real-time clock scheduling. Other ratings sit in AC drives, with the series description on the ABB ACQ580 page.

Technical specifications

Light and heavy duty on 38 A

Three ratings are published. Nominal use is 38 A for 18.5 kW. Light duty is 36.1 A for 18.5 kW with 110% overload for one minute in ten (about 39.7 A, derived). Heavy duty is 31.6 A for 15 kW with 150% for the same minute (about 47.4 A, derived). The maximum output current is 56.9 A, available for 2 seconds at start. Ratings apply up to +40 degrees C in IP21 or IP55.

For protection ABB recommends 63 A IEC fuses of type 170M1565 (aR or uR) or, for UL, 60 A fuses of type JJS-60. Typical heat loss is 523 W and the cooling air flow 179 m3/h, with a maximum noise level of 76 dBA at full fan speed. Cabinet designers should plan to remove that heat.

The frame R3 IP21 housing is 203 mm wide and 229 mm deep, 490 mm high with the gland box, and weighs 11.8 kg. The IP55 version is 490 x 206 x 237 mm at 13 kg. With a main switch or C1 filter fitted, ABB lists the IP55 body at 733 x 207 x 258 mm and 15 kg.

For efficiency studies the catalogue shows the ACQ580-01-039A-4 together with 15 kW M3AL132SMD4 at 3000 rpm (32.9 A nominal, motor efficiency 94.1%, package efficiency 91.2%); 15 kW M3BL160MLB4 at 3000 rpm (34.6 A nominal, motor efficiency 95.1%, package efficiency 92.2%); 15 kW M3BL160MLB4 at 1500 rpm (31.3 A nominal, motor efficiency 94.9%, package efficiency 91.9%), using IE5 SynRM motors from ABB. Read the package value as a calculated figure for that exact pairing.

Type code and option codes

ACQ580-01-039A-4 breaks down as ACQ580 (series), 01 (wall-mounted), 039A (rating) and 4 (380 to 480 V). The standard panel is the Hand-Off-Auto ACH-AP-H. Typical extras are +E223 for an integrated C1 filter (R1-R5), +F316 for main switch plus C1 filter (R1-R5), +C135 for flange mounting and +P944 for removing the conduit box (R5-R9).

Modbus RTU over EIA-485 is standard. Fieldbus adapters plug into slot one; the catalogue lists DeviceNet FDNA-01 (+K451, ABB code 68469341), PROFIBUS DP FPBA-01 (+K454, 68469325) and CANopen FCAN-01 (+K457, 68469376). A second slot takes extension I/O.

Data worth checking against the site: control of induction, permanent magnet and synchronous reluctance motors, IE2 efficiency class to IEC 61800-9-2, Safe Torque Off to SIL 3 / PL e, EMC class C2 as standard for ACQ580-01 and a C1 option up to 55 kW.
