Allen-Bradley 21AD052A3AYNANC0NNNN-ND-B0-C1-P1 PowerFlex 70 AC Drive
1. Product Overview
The Allen-Bradley 21AD052A3AYNANC0NNNN-ND-B0-C1-P1 is a configured PowerFlex 70 adjustable-frequency AC drive intended for industrial motor speed control, torque control, acceleration and deceleration management, and general-purpose variable-frequency drive applications.
The core 21AD052 designation identifies a high-power PowerFlex 70 drive in the 480 V class and 52 A range. In the standard PowerFlex 70 rating structure, the corresponding 480 V, 60 Hz drive is rated at approximately 52 A, 30 kW, or 40 HP, and uses Frame E construction.
The PowerFlex 70 family is designed for applications where a conventional motor starter is not sufficient and where the motor needs controlled acceleration, controlled deceleration, adjustable operating speed, improved process control, and electronic motor protection.
This particular model belongs to the larger PowerFlex 70 platform rather than being a simple fixed-speed starter. Its configuration allows the drive to be integrated into industrial machinery and control systems where a combination of motor control, programmable parameters, I/O functionality, braking capability, enclosure requirements, and installation constraints must be considered.
The catalog number is relatively long because it represents a configured industrial drive, rather than only a basic horsepower rating. The additional characters describe selected drive options and configuration characteristics. For this reason, the complete catalog number should be retained when ordering a replacement or matching an existing installation.

The standard Frame E PowerFlex 70 dimensions are approximately 280.3 mm high × 555.8 mm wide × 219.8 mm deep for the IP20/NEMA Type 1 configuration, with an approximate weight of 18.60 kg including the HIM where applicable. Frame E is also available in other enclosure arrangements, so the physical dimensions should always be checked against the exact enclosure configuration before cabinet fabrication.
4. Electrical Rating Details
The 21AD052 designation is associated with the 480 V class of the PowerFlex 70 family.
The standard PowerFlex 70 data lists the corresponding 480 V, 60 Hz 052 rating at 52 A, 30 kW, and 40 HP, with Frame E construction.
| Electrical Characteristic | Value |
|---|---|
| Nominal AC Voltage Class | 480 V AC |
| Input Configuration | 3-phase |
| Drive Current Class | 52 A |
| Normal-Duty Motor Rating | 40 HP |
| Normal-Duty Motor Rating | 30 kW |
| Frame | E |
| Motor Application | AC induction / compatible motor-control applications |
| Operating Frequency | Application programmable |
| Motor Speed Control | Variable frequency |
| Acceleration Control | Programmable |
| Deceleration Control | Programmable |
| Electronic Motor Protection | Available through drive control functions |
| Dynamic Braking | Dependent on selected configuration and external braking requirements |
The 52 A value should not be interpreted as a universal motor current under every operating condition. Actual motor current, overload requirements, ambient temperature, carrier frequency, duty cycle, motor efficiency, motor power factor, and application conditions must be considered during final drive selection.
For demanding loads, the drive should be selected according to the motor nameplate and the actual load profile rather than choosing the drive only from the motor horsepower.
5. Physical Dimensions and Weight
Because this is a Frame E PowerFlex 70 configuration, physical size is considerably larger than the smaller Frame A, B, C, and D units.
| Physical Parameter | IP20 Frame E Approximate Value |
|---|---|
| Model | 21AD052A3AYNANC0NNNN-ND-B0-C1-P1 |
| Frame | E |
| Height | 280.3 mm |
| Width | 555.8 mm |
| Depth | 219.8 mm |
| Approximate Weight | 18.60 kg |
| Approximate Weight | 41.0 lb |
| Mounting Style | Panel / cabinet mounting |
| Heat Sink Construction | Flange-like Frame E heat-sink arrangement |
| Installation Consideration | Adequate airflow and clearance required |
The published PowerFlex 70 Frame E dimensional data also identifies a flange-like heat-sink arrangement for IP20 and IP66 Frame E drives. This is important when designing a control cabinet because the heat-sink structure and required ventilation space affect the usable cabinet depth and cooling arrangement.
The dimensions above should therefore be treated as the drive body dimensions rather than the complete space required for an installation.
A real installation normally requires additional space for power cables, control wiring, grounding conductors, ventilation, heat dissipation, service access, and safe working clearance.
6. Product Introduction
The PowerFlex 70 is an industrial adjustable-frequency AC drive designed to provide controlled operation of AC motors in machinery and process equipment.
Instead of connecting a motor directly to the incoming AC supply and allowing it to run essentially at line frequency, the drive electronically controls the power delivered to the motor. This allows the motor speed to be adjusted according to the requirements of the machine.
For a 40 HP-class motor, this type of control can be particularly useful in applications where starting current, acceleration, deceleration, process speed, mechanical stress, or energy consumption must be managed.
The 21AD052 rating is positioned toward the larger end of the standard PowerFlex 70 Frame E range. It is therefore suitable for industrial equipment where a higher-power motor needs controlled operation rather than simple on/off switching.
The PowerFlex 70 platform also provides extensive parameterization. This allows engineers to configure acceleration and deceleration characteristics, motor data, speed references, current limits, control behavior, fault responses, and other operating functions according to the application.
7. Catalog Number Interpretation
The complete catalog number is:
21AD052A3AYNANC0NNNN-ND-B0-C1-P1
The most important portion for identifying the basic drive rating is the 21AD052 designation.
The PowerFlex 70 catalog-number structure uses multiple positions to identify voltage, current or horsepower class, enclosure, control, braking, feedback, human-interface options, documentation and other configuration characteristics. The standard PowerFlex 70 catalog structure confirms that the drive rating code and configuration characters are separate parts of the complete catalog number.
For practical purchasing and replacement work, it is strongly preferable to specify the complete catalog number, rather than ordering only a generic “PowerFlex 70 40 HP drive.”
This is because two drives with the same basic horsepower rating can have different enclosure, control, braking, interface, feedback, or installation configurations.
8. Product Applications
8.1 Conveyor Systems
The PowerFlex 70 is well suited to conveyor systems that require adjustable speed.
A conveyor may need different operating speeds for loading, inspection, processing, accumulation, or unloading. A variable-frequency drive allows the motor speed to be changed without relying solely on mechanical transmission changes.
The 40 HP-class 21AD052 is particularly appropriate for larger conveyors, heavy material handling systems, pallet conveyors, production-line transport equipment, and similar machinery.
Controlled acceleration can also reduce mechanical shock to belts, couplings, gearboxes, chains, and conveyor structures.
8.2 Material Handling Equipment
Material handling machinery frequently requires controlled starting and stopping.
Applications can include large conveyors, transfer systems, roller conveyors, pallet handling equipment, feeders, lifting-related auxiliary machinery, and automated production-line transport systems.
The drive can provide controlled motor speed rather than simply applying full line voltage to the motor.
This can make the machine easier to integrate with a larger automation system.
8.3 Pumps
Variable-frequency control is commonly used on industrial pumps where the required flow varies.
Instead of running the pump continuously at full speed and controlling the process primarily through a valve, a variable-speed drive can adjust motor speed according to process demand.
Applications can include process-water pumps, circulation pumps, cooling-water systems, transfer pumps, industrial fluid handling, and other compatible centrifugal-pump applications.
Proper pump and drive sizing remains important because pump torque characteristics vary with speed and pump type.
8.4 Fans and Blowers
Large industrial fans and blowers are another important application area.
Ventilation systems, cooling systems, process-air systems, dust collection equipment, combustion-air systems, and industrial exhaust systems may require variable airflow.
The PowerFlex 70 can provide adjustable motor speed so that airflow can be matched more closely to actual process requirements.
This can also help reduce unnecessary mechanical operation when full airflow is not required.
8.5 Mixers
Industrial mixers often need controlled acceleration because the material being mixed can produce significant starting torque.
A controlled acceleration profile can reduce sudden mechanical loading on the motor, gearbox, shaft, coupling, and mixing mechanism.
The drive can also allow the mixer to operate at different speeds for different production stages.
8.6 Process Machinery
The PowerFlex 70 can be integrated into a wide range of process machinery where motor speed must be adjustable.
Examples include material processing equipment, production machines, industrial feeders, machine tools, production lines, and general-purpose automated machinery.
Its programmable control architecture makes it suitable for applications where the motor behavior must be integrated with sensors, PLC logic, operator commands, or other automation equipment.
8.7 Packaging Machinery
Packaging systems often require synchronized and repeatable motor movement.
Motors may operate conveyors, feeders, rollers, pumps, fans, indexing mechanisms, or auxiliary equipment.
A programmable drive provides the ability to establish repeatable acceleration and deceleration characteristics and to adjust operating speed according to production requirements.
8.8 Heavy-Duty Industrial Machinery
The 52 A / 40 HP class makes this drive suitable for substantially larger machines than the small PowerFlex 70 ratings.
Potential applications include heavy conveyors, large pumps, large fans, industrial mixers, processing equipment, machine auxiliaries, and production machinery requiring a controlled AC motor.
The actual suitability depends on motor duty, overload requirements, ambient temperature, installation method, and the machine’s torque profile.
9. Main Advantages
9.1 Adjustable Motor Speed
One of the most important advantages is the ability to control motor speed electronically.
This allows the motor to operate at a speed appropriate for the process rather than being limited to the fixed speed associated with the incoming power frequency and motor pole count.
9.2 Controlled Acceleration
The drive can provide programmed acceleration rather than allowing the motor to accelerate immediately from a stationary condition.
This can reduce mechanical stress on couplings, belts, gearboxes, chains, shafts, and driven equipment.
9.3 Controlled Deceleration
Controlled deceleration can be useful where sudden stopping would create excessive mechanical stress or cause instability in the machine.
The deceleration profile can be configured according to the application’s requirements.
9.4 Reduced Starting Stress
A motor started directly across the line can draw a substantial starting current.
An adjustable-frequency drive provides a controlled electronic starting method, allowing motor acceleration to be managed according to programmed parameters.
This is particularly useful for larger motors and machines with significant mechanical inertia.
9.5 Flexible Application Configuration
The PowerFlex 70 platform provides extensive configuration capability.
The drive can be adapted to different motor characteristics, speed references, acceleration requirements, control schemes, and machine operating conditions.
This flexibility is one reason the PowerFlex 70 family has been used across many different industrial applications.
9.6 Industrial Automation Integration
The drive is intended for use as part of an industrial control system rather than as an isolated motor controller.
Depending on the installed configuration and options, the drive can be connected with control devices, digital signals, analog references, operator interfaces, feedback equipment, and industrial automation systems.
9.7 Suitable for Large Motors
The 21AD052 rating provides a substantially higher current and horsepower range than the smaller PowerFlex 70 models.
With a standard 480 V rating of approximately 52 A and 40 HP normal-duty capability, it is appropriate for many larger industrial motor applications.
9.8 Parameter-Based Control
Instead of relying on fixed mechanical settings, many operating characteristics can be established through drive parameters.
This makes commissioning and application adjustment easier when the machine requirements change.
For example, acceleration time, deceleration time, speed references, motor information, current limits, and protective functions can be configured according to the application.
10. Important Installation Considerations
The 21AD052 is a relatively large industrial drive, so installation planning is important.
The approximately 18.60 kg Frame E drive should be mounted on a suitable structural surface capable of supporting the drive and the associated cabling.
The cabinet must also accommodate heat dissipation.
Variable-frequency drives generate heat during operation. The cabinet design therefore needs sufficient ventilation or an appropriate thermal management system.
Power wiring and control wiring should also be arranged carefully.
High-current motor and line conductors should be routed in a manner that minimizes unwanted interference with low-level control signals.
Grounding and bonding are equally important.
The installation should follow the applicable electrical codes, drive installation requirements, motor requirements, and the specific configuration of the equipment.
11. Recommended Same-Series / Closely Related PowerFlex 70 Models
The following models are closely related to the 21AD052 and can be considered when selecting a different motor capacity within the PowerFlex 70 family.
The standard 480 V PowerFlex 70 range includes 20AD027, 20AD034, 20AD040, 20AD052, and 20AD065, among others.
| Model | Voltage Class | Current | Normal-Duty HP | Power | Frame | Approx. Dimensions | Approx. Weight |
|---|---|---|---|---|---|---|---|
| 21AD027 | 480 V AC | 27 A class | 20 HP | 15 kW | D | 219.9 × 350.0 × 169.0 mm | 9.25 kg |
| 21AD034 | 480 V AC | 34 A class | 25 HP | 18.5 kW | D | 219.9 × 350.0 × 169.0 mm | 9.25 kg |
| 21AD040 | 480 V AC | 40 A class | 30 HP | 22 kW | D | 219.9 × 350.0 × 169.0 mm | 9.25 kg |
| 21AD052 | 480 V AC | 52 A class | 40 HP | 30 kW | E | 280.3 × 555.8 × 219.8 mm | 18.60 kg |
| 21AD065 | 480 V AC | 65 A class | 50 HP | 37 kW | E | 280.3 × 555.8 × 219.8 mm | 18.60 kg |
The dimensions and weights above are frame-level values, so different enclosure configurations can change the final physical arrangement. The standard published Frame D and Frame E dimensional data gives 9.25 kg for the IP20 Frame D and 18.60 kg for the IP20 Frame E.
21AD027
The 21AD027 is a smaller PowerFlex 70 option in the 480 V class.
It is approximately a 20 HP normal-duty drive and uses Frame D construction.
It can be considered when the connected motor is smaller than the 40 HP application for which the 21AD052 is intended.
21AD034
The 21AD034 increases the capacity to approximately 25 HP normal duty.
It remains within the Frame D portion of the PowerFlex 70 family.
This can be useful when the motor requirement falls between the 20 HP and 30 HP classes.
21AD040
The 21AD040 is approximately a 30 HP normal-duty drive.
It is particularly useful when the application requires more capacity than the 25 HP model but does not require the 40 HP rating of the 21AD052.
21AD052
The 21AD052 is the model discussed in this document.
Its standard 480 V rating is approximately 52 A and 40 HP normal duty, with Frame E construction.
21AD065
The 21AD065 is the next larger standard 480 V PowerFlex 70 model in this group.
It is approximately 65 A and 50 HP normal duty.
It is a logical consideration for applications that exceed the capacity of the 21AD052 but still remain within the PowerFlex 70 Frame E range.
12. Five Popular Related Allen-Bradley Models
The following models are popular or closely related Allen-Bradley AC-drive choices from the broader PowerFlex family. They should not automatically be treated as direct drop-in replacements for the 21AD052 because physical dimensions, control architecture, option structures, communications, and application capabilities can differ.
| Model | Series | Typical Rating / Class | Voltage Class | Typical Application | Frame / Construction |
|---|---|---|---|---|---|
| 25B-D017N114 | PowerFlex 525 | 17 A class | 480 V class | General-purpose machinery, conveyors, pumps | Compact general-purpose drive |
| 20AD052 | PowerFlex 70 | 52 A | 480 V class | Industrial motor control | Frame E |
| 20AD065 | PowerFlex 70 | 65 A | 480 V class | Larger industrial motors | Frame E |
| 20F1ANE033JA0NNNNN | PowerFlex 753 | 33 A class | 480 V class | Advanced machine/process applications | Larger industrial drive platform |
| 20G11FD052AA0NNNNN | PowerFlex 755 | 52 A class | 480 V class | Advanced industrial automation and high-performance applications | High-performance drive platform |
The PowerFlex 70 models in this table use the same general family architecture as the subject product, while the PowerFlex 525, 753, and 755 models represent different generations or application classes within the broader product family.
13. PowerFlex 525 Comparison
The PowerFlex 525 is generally positioned as a compact general-purpose AC drive.
Compared with the PowerFlex 70, it is often considered when panel space, integrated features, and compact machine design are important.
However, the two series are not physically or electrically identical.
A PowerFlex 525 should therefore not be selected as a direct replacement simply because the horsepower rating appears similar.
The motor rating, input voltage, overload requirement, control architecture, communications, mounting arrangement, enclosure, and available options must all be checked.
14. PowerFlex 753 Comparison
The PowerFlex 753 is a higher-level industrial drive platform intended for more advanced machine and process applications.
Compared with the PowerFlex 70, the PowerFlex 753 can provide a different combination of control functions, option modules, feedback capabilities, communications, and system integration possibilities.
For a new machine, a PowerFlex 753 may therefore be considered where more sophisticated drive functionality is required.
For an existing PowerFlex 70 installation, however, the PowerFlex 753 should be treated as an alternative platform rather than assuming it is a direct plug-and-play replacement.
15. PowerFlex 755 Comparison
The PowerFlex 755 is another advanced AC drive platform in the same broader family.
It is particularly relevant to applications requiring sophisticated motion, speed, torque, feedback, networking, or machine-control functionality.
Its architecture and configuration options differ from the PowerFlex 70.
When considering a PowerFlex 755 as an alternative to the 21AD052, engineers should compare the complete electrical rating, motor type, control method, feedback requirement, communication system, enclosure, cabinet dimensions, and application software requirements.
16. Typical Industries
The 21AD052 PowerFlex 70 can be considered for equipment used in industries such as:
| Industry | Typical Drive Application |
|---|---|
| Manufacturing | Production machinery and conveyors |
| Material Handling | Heavy conveyors and transfer equipment |
| Water Treatment | Pumps and auxiliary equipment |
| HVAC | Large fans and blowers |
| Food Processing | Pumps, conveyors and mixers |
| Packaging | Conveyors and production-line machinery |
| Chemical Processing | Pumps, mixers and process equipment |
| Plastics | Extrusion auxiliaries and material handling |
| Metal Processing | Conveyors, fans and auxiliary machinery |
| General Industrial Automation | AC motor speed control |
17. Application Selection Guidelines
When using the 21AD052, the first consideration should be the motor nameplate.
The motor voltage should correspond to the drive’s applicable output range.
The motor full-load current should also be compared with the drive rating.
Motor horsepower alone should not be the only selection criterion.
For example, two motors with the same horsepower can have different full-load current requirements depending on voltage, efficiency, power factor, motor design, and operating conditions.
The load type is also important.
A centrifugal fan or pump generally has a different torque-speed relationship from a conveyor, mixer, compressor, or high-inertia machine.
The required overload capability should therefore be considered during drive selection.
18. Cabinet Design Considerations
Because the 21AD052 is a Frame E drive, it occupies considerably more cabinet space than the smaller PowerFlex 70 units.
The nominal drive body dimensions are approximately:
280.3 mm × 555.8 mm × 219.8 mm
with an approximate weight of:
18.60 kg.
The cabinet should not be designed using these numbers alone.
Additional space should be provided for cable entry, power terminals, control wiring, airflow, service access, and heat dissipation.
The cabinet designer should also consider the heat generated by the drive and other components installed in the same enclosure.
19. Maintenance Advantages
The PowerFlex 70 platform uses electronic parameter-based configuration, making it possible to record drive settings and use them as part of maintenance documentation.
For maintenance teams, this can simplify troubleshooting because operating parameters, motor information, fault conditions, and control settings can be documented.
A well-maintained spare-drive strategy should preserve the complete catalog number and configuration information.
This is especially important for a long catalog number such as:
21AD052A3AYNANC0NNNN-ND-B0-C1-P1
Replacing it with only a generic “40 HP PowerFlex 70” may not reproduce all of the original configuration characteristics.
20. Replacement and Spare-Parts Considerations
When purchasing a replacement, the following information should be compared:
| Replacement Check | Requirement |
|---|---|
| Complete Catalog Number | 21AD052A3AYNANC0NNNN-ND-B0-C1-P1 |

| Dimensions | Approximately 280.3 × 555.8 × 219.8 mm for IP20 Frame E |
| Weight | Approximately 18.60 kg |
21. Overall Product Positioning
The Allen-Bradley 21AD052A3AYNANC0NNNN-ND-B0-C1-P1 can be positioned as a high-power industrial member of the PowerFlex 70 AC drive family.
Its main characteristics are its 480 V class, 52 A current class, 40 HP / 30 kW normal-duty rating, and Frame E construction.
It is intended for applications where an industrial AC motor needs adjustable speed and controlled operation rather than simple line-voltage starting.
The drive is particularly relevant to larger conveyors, pumps, fans, blowers, mixers, process machinery, material handling systems, and other industrial equipment.
Its Frame E construction provides a larger physical platform appropriate to its higher power rating.
The approximately 18.60 kg weight and 280.3 × 555.8 × 219.8 mm IP20 Frame E dimensions should be taken into account when designing or modifying an electrical cabinet.
