ABB ACS580-01-073A-4 AC Drive 37 kW 73 A

A 37 kW ACS580-01 for 400 V motors

At 37 kW this rating is typical for substantial pump stations and fan banks, and the heat loss rises to 858 W so cabinet or room cooling needs checking. The matching ABB part is the ACS580-01-073A-4, a 3-phase drive for 380 to 480 V with 73 A nominal output current and 37 kW typical motor power, packed into a frame R4 body that stands 203 mm wide.

ABB aims the ACS580-01 at light industry such as food and beverage, plastics, textiles, material handling and agriculture. A DC/AC choke, EMC filter, Modbus RTU port and STO function come as standard, so a panel builder needs little extra hardware. Browse more in AC drives or read the ABB ACS580 series page.

Technical specifications

Sizing the ACS580-01-073A-4 for your motor

Overload data decide whether ACS580-01-073A-4 is the right size. In light-duty use the catalogue allows 68.4 A continuously and 110% of that, about 75.2 A, for one minute in ten at 40 degrees C. In heavy-duty use the continuous figure drops to 61 A, which allows 150%, about 91.5 A, for the same minute. Select by motor nominal current, not only by kilowatts.

Cabinet designers should allow 858 W and 150 m3/h of air flow. Maximum recommended motor cable is 300 m, and the catalogue fuse is 100 A gG (90 A UL Class T). If the load turns out to be 30 kW or less, ACS580-01-062A-4 may fit (62 A); above 45 kW the next type is ACS580-01-089A-4 at 89 A.

Ordering code and enclosure options

Decode the code as follows: ACS580 is the product series, 01 the wall-mounted construction, 073A the rating designation from the catalogue table, and 4 the 380 to 480 V voltage range. Option codes follow with a plus sign: +B056 (IP55 / UL Type 12, R1 to R9), +B063 (IP66 / UL Type 4X), +F278 (integrated main switch, R1 to R5), +E223 (integrated C1 filter, R1 to R5), +C135 (flange mounting) and +P944 (conduit box removal, R5 to R9).

The IP55 version of this frame measures 636 (879 with options) x 203 x 265 mm. The catalogue dimension table lists IP66 only for frames R1 to R3. Fieldbus options include PROFIBUS DP (+K454, FPBA-01), Modbus RTU (+K458, FSCA-01), Two-port EtherNet/IP (+K490, FEIP-21) and Two-port Modbus/TCP (+K491, FMBT-21). Order the exact type code shown above and add options only where the project needs them.

Built-in features that reduce panel hardware

Several items that are often bought separately for a drive of this size are already inside the ACS580-01-073A-4:

• DC/AC choke: reduces input current harmonics, which helps where several drives share one transformer or a generator.
• EMC filter: limits conducted emissions back into the supply network.
• Safe Torque Off (STO): a hardware input that removes torque from the motor, used as part of a machine safety function designed by the integrator.
• Modbus RTU: an embedded fieldbus port for connection to a PLC or building management system without an extra adapter.

Pump and fan duties at 37 kW

Centrifugal pumps and fans are variable-torque loads, so power falls steeply as speed falls. That is why most 37 kW pump and fan applications are sized on the light-duty rating of 68.4 A. Conveyors, mixers, positive displacement pumps and crushers start against high torque and should be checked against the heavy-duty figure of 61 A and the 150% overload allowance instead. If the motor nameplate current sits close to either limit, step up a size rather than running the drive at its edge.

Installation and commissioning notes

The R4 frame is wall-mounted and cooled by forced air, so leave the free space above and below that the hardware manual specifies and make sure the 150 m³/h of cooling air can actually leave the enclosure. With 858 W of typical losses, a sealed cabinet without ventilation or air conditioning will overheat quickly.

• Use the recommended input fuses (IEC 100 A gG) to keep the protection coordinated with the drive.
• Use a symmetrical shielded motor cable, ground the shield at both ends with 360° glands and keep it within the 300 m maximum.
• Run control and fieldbus cables away from motor cables, crossing at right angles where unavoidable.
• Enter motor nameplate data accurately before the first start and run the identification routine when the application allows.

Derating for heat and altitude

The catalogue ratings apply at a stated reference ambient. Above that temperature, or at high altitude, output current must be derated according to the ABB hardware manual. In hot climates this is not a formality; it should be part of the sizing calculation.

Operating in Oman and the GCC

Water pumping stations, district cooling, HVAC air handling units and process plants across the region commonly use drives in the 30 to 45 kW range. Summer temperatures in equipment rooms often exceed what an IP21 drive is designed for unless the room is cooled, and fine dust can block heat sinks. Plan for filtered or conditioned air, clean the heat sink at regular intervals and consider a higher-rated enclosure or a cabinet solution where the drive is in a dusty plant area.
