ABB ACS580-01-039A-4 AC Drive 18.5 kW 38 A

ACS580-01-039A-4 at a glance

Looking for a 18.5 kW ACS580 on a 400 V network? ACS580-01-039A-4 is the catalogue type: 38 A nominal output, frame R3, wall mounting and a base of 203 x 229 mm. An 18.5 kW motor is a regular size for centrifugal pumps and fans on utility skids, and this type has 38 A of nominal current inside the R3 housing.

It belongs to the ACS580-01 line that ABB describes as a drive for compressors, conveyors, pumps, extruders, centrifuges, mixers and fans. Choke, EMC filter, Modbus RTU and Safe Torque Off are built in, and the assistant control panel is delivered with the unit. Other ratings sit in the AC drives category, and the series overview is on the ABB ACS580 drive page.

Technical specifications

Overload, fuse and cooling data for the ACS580-01-039A-4

The catalogue splits the rating into two duty classes. Light duty is 36.1 A (18.5 kW) with a 110% overload for 60 seconds, roughly 39.7 A. Heavy duty is 31.6 A (15 kW) with 150% for 60 seconds, roughly 47.4 A. The maximum output current of 56.9 A is available for 2 seconds at start. Check the load profile against these figures.

Cabinet designers should allow 528 W and 179 m3/h of air flow. Maximum recommended motor cable is 300 m, and the catalogue fuse is 50 A gG (60 A UL Class T). If the load turns out to be 15 kW or less, ACS580-01-033A-4 may fit (32 A); above 22 kW the next type is ACS580-01-046A-4 at 45 A.

How to read the type code

An order for this drive starts with ACS580-01-039A-4. In that string 01 is wall-mounted, 039A is the catalogue rating and 4 the voltage class. ABB prints these plus codes: +B056 IP55 / UL Type 12, +B063 IP66 / UL Type 4X, +F278 main switch (R1 to R5), +E223 C1 filter (R1 to R5), +C135 flange mounting, +P944 conduit box removal (R5 to R9).

Wet or dusty site? ABB lists +B056 for IP55, and frame R3 then measures 490 (733 with options +F287, +F316 or +E223) x 206 x 237 mm. IP66 / UL Type 4X (+B063) measures 647 x 277 x 260 mm, 26.4 kg. Network adapters such as FPBA-01, FSCA-01, FEIP-21 and FMBT-21 plug in with codes +K454, +K458, +K490 and +K491.

Key features of the ACS580-01-039A-4

• Built-in DC choke for reduced input harmonics, so no separate line reactor is normally needed.
• Integrated EMC filter and embedded Modbus RTU on the control board, with optional fieldbus adapters for other networks.
• Safe Torque Off as standard for machine safety functions.
• Assistant control panel with set-up wizards and a Bluetooth panel option for commissioning from a phone.
• Energy optimizer and energy calculators that show savings against direct-on-line operation.
• Coated circuit boards as standard, which help in humid or dusty environments.

Choosing the duty class

Centrifugal pumps and fans have a load torque that rises with speed, so the light-duty rating of 36.1 A (18.5 kW) is normally the right comparison for these machines. Positive displacement pumps, loaded conveyors, mixers and crushers can demand high torque at low speed and during starting, and for those the heavy-duty current of 31.6 A (15 kW) should be compared with the motor current. If an 18.5 kW motor drives a constant-torque load, the next larger ACS580 rating is often the better choice. The decision should always be based on the motor nameplate current and the expected overload profile rather than on the power figure alone.

Installation and maintenance

• Mount the drive vertically with the free space above and below that ABB specifies for frame R3, so cooling air can reach the 179 m³/h fan.
• Use symmetrical shielded motor cable and 360° earthing of the shield at the glandbox for EMC compliance.
• Protect the supply with the recommended 50 A gG fuses (IEC) or the UL fuse equivalent.
• Replace the cooling fan and check capacitors according to the maintenance intervals in the hardware manual.
• Back up drive parameters to the control panel or a PC before any service work.

Applications in Oman and GCC facilities

An 18.5 kW drive of this type often controls booster pumps in building water systems, cooling tower fans, chilled water pumps in district cooling and transfer pumps in water treatment. In these duties the variable speed control saves energy compared with throttling valves or dampers, which is significant where air conditioning loads dominate summer electricity use. The IP21 enclosure is intended for clean electrical rooms; for outdoor or dusty pump houses, the drive should be installed inside a suitably rated, ventilated or cooled cabinet. The 528 W typical heat dissipation is the figure to use when sizing panel cooling, and high ambient temperatures may require derating according to the hardware manual.

What to include in your RFQ

• Type code ACS580-01-039A-4 and quantity, plus any option codes such as a higher enclosure class.
• Motor nameplate data and the type of load (pump, fan, conveyor).
• Fieldbus requirement, if not Modbus RTU.
• Accessories such as a Bluetooth control panel, door mounting kit or output filters.
• Delivery site and project documentation needs.

Datasheet and quotation

The linked catalogue, ABB document 3AUA0000145061, is the reference for every rating on this page. Seven Star LLC supplies the ACS580-01-039A-4 to project and maintenance buyers on request; a quotation lists availability and lead time once we have your duty details.

Always check the type code, options, motor current and ambient conditions against your own documents before ordering, since catalogue ratings apply at 40 degrees C and altitudes up to 1000 m.
