---

4. Product Introduction

The 20G1ABF330AN0NNNNN is intended for applications where the motor power requirement has moved beyond the capacity of smaller industrial drives.

With a 330 A output rating, this drive is suitable for substantial industrial motors and large mechanical systems.

Its 690 VAC voltage class makes it particularly appropriate for high-power industrial installations where large motors are operated at medium-voltage-class low-voltage distribution levels.

The drive is part of the PowerFlex 755 architecture, a platform developed for demanding industrial motor-control applications.

Its design combines a high-power drive section, forced-air cooling, network communication, configurable motor-control functions, and a large Frame 8 mechanical structure.

The model is especially appropriate for installations where the drive is integrated into a plant-wide automation system rather than operated as a stand-alone local machine controller.

---

5. 690 VAC Voltage Class

The 690 VAC rating is a major characteristic of this model.

Large industrial motors often require substantial electrical power.

At higher motor voltage, the current required for a given power level can be lower than at lower voltage.

This can influence the sizing of:

• Motor cables.
• Switchgear.
• Protective equipment.
• Transformers.
• Motor distribution systems.
• MCC equipment.
• Electrical bus systems.

For large industrial plants, a 690 VAC drive can therefore be an effective choice for high-power motor applications.

The 20G1ABF330AN0NNNNN is not intended as a compact machine drive.

It belongs to the large industrial drive category and is much better suited to centralized process equipment, large pumps, fans, conveyors, crushers, and similar machinery.

---

6. 330 A Output Capacity

The drive provides a nominal output current rating of 330 A.

This is a substantial current capability.

It makes the model suitable for large motors where smaller PowerFlex drive configurations would not provide sufficient output current.

When selecting the drive for a specific motor, however, the motor nameplate current should be treated as a primary selection parameter.

The motor’s kW rating should not be used by itself.

Other factors include:

• Motor full-load current.
• Starting torque.
• Continuous torque.
• Peak torque.
• Acceleration time.
• Deceleration time.
• Operating speed range.
• Load inertia.
• Duty cycle.
• Ambient temperature.
• Altitude.
• Overload requirement.

---

7. Low Duty, Normal Duty and Heavy Duty Ratings

The model provides three major power ratings.

Duty Rating	Power
Low Duty	355 kW
Normal Duty	315 kW
Heavy Duty	250 kW

These ratings allow the same drive platform to be evaluated against different load profiles.

Low Duty – 355 kW

The 355 kW Low Duty rating represents the highest nominal power capability of the three classifications.

It is particularly relevant to applications with relatively moderate overload requirements.

Typical variable-torque applications can often be evaluated against this rating.

Examples include:

• Large centrifugal pumps.
• Large fans.
• Ventilation systems.
• Certain blowers.

---

Normal Duty – 315 kW

The 315 kW Normal Duty rating is suitable for a broad range of continuous industrial motor applications.

It provides a useful balance between motor capacity and overload requirements.

Typical applications may include:

• Conveyors.
• Pumps.
• Fans.
• Blowers.
• Process equipment.
• Material-handling systems.

---

Heavy Duty – 250 kW

The 250 kW Heavy Duty rating is intended for applications requiring greater overload capability.

Heavy Duty applications can involve:

• High starting torque.
• Higher acceleration loads.
• Greater mechanical inertia.
• Frequent cycling.
• More demanding load conditions.

Potential applications include:

• Crushers.
• Heavy conveyors.
• Mixers.
• Processing equipment.
• Certain high-inertia machines.

The actual duty classification should always be selected according to the motor and load profile.

---

8. Power Rating Conversion

For reference, the approximate horsepower equivalents are:

Rating	kW	Approx. HP
Low Duty	355 kW	~476 HP
Normal Duty	315 kW	~422 HP
Heavy Duty	250 kW	~335 HP

The kW values are the more appropriate values for technical selection when working with modern metric industrial equipment.

---

9. Frame 8 Construction

The 20G1ABF330AN0NNNNN uses a Frame 8 construction.

This is a large physical platform intended for high-power motor-control applications.

Frame 8 equipment requires substantially more installation space than compact variable frequency drives.

The approximate physical envelope for this configuration can be considered:

2100 mm high × 610 mm wide × 600 mm deep

with an approximate complete-drive weight of:

634 kg.

These figures are suitable for preliminary engineering and layout work.

For final cabinet design, shipping calculations, structural calculations, and lifting plans, the dimensional drawing and actual equipment configuration should be used.

---

10. Dimensions and Weight

Mechanical Parameter	Approximate Specification
Model	20G1ABF330AN0NNNNN
Frame	Frame 8
Height	~2100 mm
Width	~610 mm
Depth	~600 mm
Overall Dimensions	~2100 × 610 × 600 mm
Weight	~634 kg
Mechanical Style	600 mm Deep MCC Style
Cooling	Forced Air
Enclosure	Type 1
Protection	IP20

The 600 mm deep MCC-style configuration is part of the catalog description for the ABF high-power family. 

The weight of approximately 634 kg should be regarded as an engineering estimate for the complete Frame 8 assembly rather than the weight of an individual module or shipping component.

---

11. Air-Cooled / Forced-Air Design

The drive uses a forced-air cooling architecture.

At several hundred kilowatts of motor capacity, thermal management is a major part of drive design.

The air-cooled architecture provides several practical advantages.

There is no external liquid-cooling circuit required for normal drive cooling.

The system does not need a dedicated coolant pump.

There is no external liquid reservoir.

There is no separate liquid heat exchanger dedicated to the drive.

This can simplify the overall plant installation.

However, the electrical room must provide sufficient airflow.

The intake and exhaust paths must remain unobstructed.

Hot exhaust air should not be allowed to recirculate directly into the drive intake.

---

12. AC Input With Precharge

The 20G1ABF330AN0NNNNN uses AC input with precharge.

High-power drives contain substantial DC-bus capacitance.

When power is initially applied, the DC bus must be charged.

The precharge system controls this charging process and helps prevent an uncontrolled initial charging current.

This is particularly important in a high-power drive because the stored electrical energy and input capacity are substantially greater than those of a small industrial inverter.

---

13. No DC Terminals

The catalog configuration specifies:

No DC terminals

This means the standard configuration is based around conventional AC input operation.

The model should not automatically be considered suitable for every common-DC-bus architecture.

If the project requires:

• Shared DC bus operation.
• Regenerative DC architecture.
• External DC power input.
• DC coupling between drives.
• Special energy-storage integration.

additional engineering and a suitable drive configuration are required.

---

14. Filtered Configuration

The drive is specified as a filtered configuration.

Variable frequency drives use high-frequency switching devices.

This switching can produce electromagnetic interference.

Filtering helps control high-frequency electrical noise and contributes to the overall EMC design.

However, good EMC performance is not determined by the drive filter alone.

The installation should also consider:

• Grounding.
• Shielding.
• Motor cable construction.
• Cable length.
• Cabinet bonding.
• Control-cable separation.
• Network cable routing.
• Motor-frame grounding.
• Proper cable termination.

---

15. CM Jumper Removed

One of the most important configuration characteristics of the AN0 version is:

CM Jumper Removed

The catalog coding distinguishes the common-mode capacitor jumper configuration.

A simplified comparison is:

Configuration	CM Jumper
AN0	Removed
JN0	Installed

The newer J-series configuration uses the installed jumper arrangement and is listed as the preferred current configuration.

This distinction is particularly important when replacing an AN-series drive with a J-series drive.

The replacement should not be treated as a simple mechanical substitution without reviewing the grounding, EMC, and system configuration.

---

16. No Dynamic Braking

The standard configuration specifies:

Dynamic Braking: None

This is important when evaluating applications with high rotating inertia.

For applications such as:

• Large pumps.
• Large fans.
• Blowers.
• Certain process machines.

dynamic braking may not be required.

However, high-inertia applications may need additional braking analysis.

Examples include:

• Large conveyors.
• Crushers.
• Centrifuges.
• Large mixers.
• Certain hoisting systems.
• Rapid-cycle equipment.

If rapid stopping is required, the standard no-dynamic-braking configuration should not be assumed to satisfy the application.

---

17. No HIM Configuration

The AN0 configuration is supplied as:

Blank / No HIM

This means the drive does not include a local operator interface as part of the standard catalog configuration.

This can be advantageous in installations where the drive is controlled from:

• PLC.
• HMI.
• SCADA.
• DCS.
• EtherNet/IP network.
• Central control room.

A no-HIM configuration can provide a clean centralized-control architecture.

---

18. Local HIM Alternatives

If local drive access is required, related configurations are available.

Model	HIM Configuration
20G1ABF330AN0NNNNN	No HIM
20G1ABF330AN2NNNNN	Enhanced LCD Full Numeric Handheld / Local HIM
20G1ABF330JN0NNNNN	No HIM
20G1ABF330JN2NNNNN	Enhanced LCD Full Numeric Handheld / Local HIM
20G1ABF330JN4NNNNN	Enhanced LCD Full Numeric Door-Mounted HIM

This gives the same basic 330 A drive platform several different operator-interface options.

---

19. Embedded EtherNet/IP

The embedded EtherNet/IP interface is one of the most useful features for modern industrial automation.

The drive can be incorporated into a networked control architecture.

Typical exchanged information can include:

Information	Typical Purpose
Start Command	Motor starting
Stop Command	Motor stopping
Speed Reference	Speed control
Actual Speed	Feedback
Output Frequency	Monitoring
Output Current	Load monitoring
Drive Status	Operating status
Fault Status	Fault handling
Warning Status	Preventive maintenance
Diagnostic Data	Troubleshooting

This allows the drive to function as part of a larger automated production system rather than operating as an isolated motor controller.

---

20. Typical Network Architecture

A typical installation may be structured as:

PLC

↓

EtherNet/IP

↓

PowerFlex 755

↓

690 VAC Motor

↓

Mechanical Load

The control system can issue speed and operating commands while receiving drive status and diagnostic information.

For a large industrial plant, this can simplify centralized supervision.

---

• Equipment-room access.
• Door dimensions.
• Transportation route.
• Floor loading.
• Lifting equipment.
• Cable routing.
• Ventilation.
• Service clearance.
• Maintenance access.
• Electrical isolation.

The approximate 634 kg weight also means that ordinary small equipment-handling methods may not be sufficient.

A suitable lifting and transportation plan should be established before installation.

---

35. Ventilation Requirements

The drive’s forced-air cooling system requires adequate airflow.

The installation should avoid:

• Blocked air inlets.
• Blocked air outlets.

• Correct motor connections.
• Proper grounding.
• Proper EMC bonding.
• Adequate maintenance access.

The approximate 634 kg weight should be considered when designing the supporting structure.

---

58. Why Choose the 330 A Version?

The 330 A model is a useful middle point within the 690 VAC Frame 8 family.

It is larger than the 265 A version but smaller than the 370 A and 415 A versions.

This makes it useful when the motor requires:

• More than approximately 265 A.
• Less than approximately 370 A.

It provides a substantial 315 kW Normal Duty rating while remaining within the same general Frame 8 platform.

---

59. Why Choose the JN0 Replacement?

For a new project or replacement of an AN0 unit, the 20G1ABF330JN0NNNNN is the natural first candidate.

The principal electrical specifications remain:

• 690 VAC.
• 330 A.
• 355 kW LD.
• 315 kW ND.
• 250 kW HD.
• Frame 8.
• Air cooled.
• Embedded EtherNet/IP.
• No HIM.

The important configuration change is the CM jumper.

Because the original AN0 is discontinued, replacement engineering should verify all control, grounding, EMC, mechanical, and parameter requirements before installation. 

63. Final Summary

The Allen-Bradley 20G1ABF330AN0NNNNN is a high-power PowerFlex 755 AC drive belonging to the PowerFlex 750-Series.

Its principal rating is 690 VAC, three-phase, 330 A, with approximately 355 kW Low Duty, 315 kW Normal Duty, and 250 kW Heavy Duty capacity.

It uses a Frame 8, 600 mm deep MCC-style, air-cooled construction and is designed for large industrial motor-control applications.

The configuration includes embedded EtherNet/IP, AC input with precharge, no DC terminals, filtered operation, CM jumper removed, no dynamic braking, and no HIM.

The approximate physical envelope is 2100 × 610 × 600 mm, with an approximate weight of 634 kg.

The model is particularly suitable for large pumps, fans, blowers, conveyors, crushers, mining machinery, cement equipment, water-treatment systems, material-handling equipment, and large process machines.

One important consideration is lifecycle status.

The 20G1ABF330AN0NNNNN is a discontinued AN-series product, with 20G1ABF330JN0NNNNN listed as the direct replacement.

The JN0 replacement maintains the same fundamental 690 VAC, 330 A, 355/315/250 kW electrical platform while using the newer CM jumper installed configuration. 

If local operator access is required, 20G1ABF330JN2NNNNN is a more suitable related configuration because it provides the Enhanced LCD full numeric handheld/local HIM.

If a permanent operator interface is required, 20G1ABF330JN4NNNNN is the appropriate related configuration with a door-mounted HIM.

If additional current capacity is needed, 20G1ABF370JN0NNNNN and 20G1ABF415JN0NNNNN provide progressively larger 690 VAC alternatives.

For compact machinery, the PowerFlex 523 and PowerFlex 525 families are more appropriate.

For very large industrial systems, other PowerFlex 755 Frame 8 configurations provide substantially higher current capacity.

Overall, the 20G1ABF330AN0NNNNN represents a high-capacity industrial drive platform intended for serious large-motor applications rather than small or general-purpose machinery.

Its strongest characteristics are the combination of 690 VAC operation, 330 A output current, 355 kW Low Duty capability, 315 kW Normal Duty capability, 250 kW Heavy Duty capability, Frame 8 construction, forced-air cooling, embedded EtherNet/IP, and centralized no-HIM architecture.

For an existing installation, the original AN0 catalog number remains important for identifying the installed equipment.

For new procurement or replacement planning, however, the 20G1ABF330JN0NNNNN should be considered first, with the exact replacement installation checked for electrical, mechanical, grounding, EMC, control, and application compatibility.
