The ABB 3AUA0000123756 is the ABB product identification number for the
ACS880-01-031A-2, a low-voltage industrial wall-mounted single drive from the
ABB ACS880 family. The drive is designed for demanding industrial motor control applications
where accurate speed, torque and process control are required.

According to ABB’s product information, the ACS880-01-031A-2 has an IEC standard-duty nominal
output power of 7.5 kW and an output current rating of 31 A
at the 230 V class. The UL rating is 10 hp with a 29.3 A rating at 230 V. This combination
makes the drive suitable for a broad range of industrial machinery and motor-driven equipment.

ABB 3AUA0000123756 Product Overview

The ABB 3AUA0000123756 belongs to the ACS880 family of industrial drives. The ACS880 platform
is developed for applications where reliable motor control and flexible integration are important.
It can be used in many industrial processes involving rotating machinery and variable-speed
motor operation.

The ACS880-01 series is a wall-mounted drive configuration intended to simplify installation
in industrial control cabinets and electrical equipment rooms. The drive provides an integrated
solution for converting electrical power into controlled variable-frequency output power for
compatible three-phase AC motors.

By controlling motor speed and torque electronically, the drive can help machinery operate at
the required process speed rather than relying on fixed-speed operation. This makes variable
frequency control useful in applications where production speed, acceleration, deceleration or
torque must be adjusted according to process requirements.

Technical Specifications

Motor Speed and Torque Control

The primary purpose of the ABB 3AUA0000123756 is to provide controlled electrical power to an
AC motor. Instead of operating the motor directly from a fixed-frequency supply, the drive
regulates the frequency and voltage delivered to the motor according to the selected control
strategy.

This allows the motor to operate at different speeds according to the requirements of the
connected machinery. Variable-speed operation can be particularly valuable in processes where
motor speed must change during production, where acceleration needs to be controlled, or where
torque demand varies during operation.

The ACS880 platform is designed for industrial applications requiring more than simple
frequency adjustment. Its architecture supports sophisticated motor control and integration
into larger automation systems, making the ACS880-01 suitable for machinery and processes
where accurate motor behavior is important.

Industrial Applications

The ABB ACS880-01-031A-2 can be applied to a wide range of industrial machinery. Typical
applications include conveyors, pumps, fans, compressors, mixers, material-handling equipment
and other rotating machinery requiring adjustable motor speed.

In conveyor applications, variable-speed control can be used to match material movement with
upstream and downstream production equipment. In pumping and fan applications, motor speed can
be adjusted according to process requirements instead of maintaining constant full-speed
operation.

The drive is also suitable for applications involving machinery where controlled acceleration
and deceleration are required. By regulating the motor electronically, the drive can provide
a controlled transition between operating speeds, helping the overall machine achieve more
predictable operation.

ACS880-01 Wall-Mounted Configuration

The ACS880-01-031A-2 uses a wall-mounted installation format. This configuration is appropriate
for industrial control cabinets and equipment installations where the drive is installed as
an individual drive close to the associated motor control equipment.

A wall-mounted arrangement can simplify access to the drive during installation and maintenance.
Cabinet designers should nevertheless provide sufficient clearance around the drive according
to ABB installation requirements and allow appropriate airflow for thermal management.

The exact enclosure and installation environment should be considered together with the
surrounding electrical equipment. Cable routing, grounding, cooling, protection devices and
motor connections should all be incorporated into the overall installation design.

Power Rating and Electrical Selection

The IEC standard-duty rating of the ABB 3AUA0000123756 is 7.5 kW with an output current rating
of 31 A. For UL applications, ABB specifies a 10 hp rating with a 29.3 A output current at
the 230 V class.

When selecting a drive, motor current should be considered together with the motor’s rated
power, operating voltage, load profile and required overload performance. A drive should not
be selected only by comparing nominal motor horsepower because different applications can
require substantially different current and overload capabilities.

The ACS880-01-031A-2 is therefore best specified by considering the complete motor and process
requirements. The 31 A IEC rating provides the primary reference for standard-duty industrial
applications, while the UL rating provides the corresponding North American reference.

Control System Integration

Industrial variable frequency drives are commonly integrated into larger automation systems.
The ACS880 family provides a platform for connecting motor control with process-level automation,
allowing speed and torque commands to be coordinated with other equipment.

Depending on the selected configuration and installed options, the ACS880 platform can support
different control and communication arrangements. The actual interface configuration should be
verified against the specific drive, installed option modules and application requirements.

For system design, engineers should distinguish between the basic drive product number and any
additional option codes. Accessories and communication modules can change the final system
configuration, so the complete product identification should be checked when replacing an
existing drive.

Typical Applications

• Industrial conveyor systems
• Pump and fan applications
• Industrial compressors
• Material handling machinery
• Mixing equipment
• Process machinery
• Production line equipment
• Machine tools and rotating machinery
• Industrial automation systems
• Variable-speed motor applications

Product Identification

Correct identification is important when working with ABB ACS880 drives because many models
have similar physical configurations while differing in voltage class, current rating, power
rating and installation arrangement.

The ABB product number 3AUA0000123756 corresponds to the ACS880-01-031A-2.
The product number should be checked against the type designation shown on the drive nameplate
when selecting a replacement or verifying an installed unit.

The ACS880-01-031A-2 should also be distinguished from other ACS880-01 models with similar
numbering. For example, the current rating and power rating can change between models even
when the general series and enclosure concept remain the same.

Conclusion

The ABB 3AUA0000123756 is the product ID for the
ACS880-01-031A-2, a low-voltage industrial wall-mounted AC drive designed for
variable-speed motor control. ABB specifies an IEC standard-duty rating of 7.5 kW and 31 A at
the 230 V class, with a UL rating of 10 hp and 29.3 A.

As part of the ABB ACS880 family, the drive is suitable for industrial machinery requiring
controlled motor speed and torque. Its wall-mounted format and industrial drive architecture
make it appropriate for applications such as conveyors, pumps, fans, compressors, mixers and
other variable-speed equipment.

When applying the ABB 3AUA0000123756, the motor voltage, rated current, power, load profile,
required overload capability, installation environment and available control interfaces should
be evaluated together. The exact ABB product number and ACS880 type designation should also be
verified before selecting the drive for an existing installation.
