The 630 A, 600 VAC, 520 kW-class electrical characteristics and the Frame 9/IP20 configuration are consistent across the available technical specifications for this model.

4. Electrical Rating

The 630 A output-current rating is one of the defining characteristics of the 20G11BE630AN0NNNNN.

This is not a compact machine-level inverter. It is a large industrial drive designed for high-power motor applications.

Its commonly specified horsepower ratings are:

Duty	Horsepower Rating	Approximate Power
Light Duty	800 HP	597 kW
Normal Duty	700 HP	522 kW
Heavy Duty	600 HP	448 kW

A separate technical listing gives approximately 520 kW normal-duty output and 445 kW heavy-duty output, illustrating that kW ratings can be presented somewhat differently depending on the applicable rating convention.

For actual engineering selection, motor nameplate current should take priority over simple horsepower conversion.

The correct drive selection depends on:

• Motor voltage
• Motor full-load current
• Motor horsepower
• Duty cycle
• Starting torque
• Acceleration time
• Overload requirement
• Load inertia
• Motor cooling
• Operating speed range

5. 600 VAC Three-Phase Operation

The 20G11BE630AN0NNNNN is designed for a 600 VAC, three-phase electrical system.

This voltage class is commonly associated with large industrial motor installations.

Using a higher voltage class allows large motor systems to operate at substantial power levels without requiring the same current levels that would be necessary at lower voltages.

For a complete installation, engineers should evaluate:

• Incoming voltage
• Voltage tolerance
• Frequency
• Short-circuit current
• Transformer capacity
• Feeder capacity
• Motor voltage
• Motor current
• Grounding system
• Cable sizing
• Protective equipment

6. 630 A Output Capacity

The 630 A output rating places this model in the high-power industrial-drive category.

A 630 A drive is suitable for large motors used in:

• Pumping stations
• Large fans
• Blowers
• Conveyors
• Mining systems
• Cement plants
• Water-treatment facilities
• Wastewater facilities
• Material-handling systems
• Industrial process equipment

The large current rating also provides additional flexibility when selecting motors within the applicable duty range.

7. Light-Duty, Normal-Duty and Heavy-Duty Operation

Understanding the three duty ratings is important.

A drive rated for 800 HP Light Duty should not automatically be considered suitable for every 800 HP motor.

Different applications demand different overload capabilities.

Duty Category	Typical Load Characteristic	20G11BE630AN0NNNNN Rating
Light Duty	Variable-torque / lower overload	800 HP
Normal Duty	General industrial operation	700 HP
Heavy Duty	Higher torque / greater overload	600 HP

For example, a large centrifugal fan may operate comfortably within a light-duty rating, while a heavily loaded conveyor may require a lower horsepower selection because of its higher torque demand.

This is why motor current and application duty should always be evaluated together.

8. Frame 9 Construction

The drive uses a Frame 9 construction.

Frame 9 is intended for large-power applications where the power section, cooling system, bus structure and electrical connections require substantially more physical space than a compact drive.

This frame size also affects:

• Cabinet arrangement
• Cable entry
• Airflow
• Maintenance access
• Floor loading
• Transportation
• Lifting
• Service clearance

A Frame 9 drive should therefore be treated as major industrial electrical equipment rather than a small cabinet component.

9. 600 mm Deep MCC-Style Construction

The model is configured as a 600 mm deep MCC-style drive.

Mechanical Parameter	Specification
Model	20G11BE630AN0NNNNN
Frame	9
Package Style	MCC Style
Depth	Approx. 600 mm
Width	Configuration Dependent
Height	Configuration Dependent
Enclosure	Type 1
Protection	IP20
Cooling	Forced Air
Installation	Indoor Industrial
Mounting	MCC / Industrial Cabinet
Cable Space	Required
Service Space	Required
Ventilation Space	Required

The 600 mm depth should be regarded as a package-depth characteristic rather than the complete installation footprint.

Power cables, control cables, ventilation paths and maintenance clearance all require additional space.

For a final cabinet drawing, the actual mechanical configuration should be checked before fabrication.

10. Dimensions

The most useful general dimensional information for this model is the 600 mm deep MCC-style construction.

Dimension	Specification
Model	20G11BE630AN0NNNNN
Depth	Approx. 600 mm
Width	Configuration Dependent
Height	Configuration Dependent
Overall Footprint	Configuration Dependent
Front Clearance	Required
Cable Clearance	Required
Cooling Clearance	Required
Service Access	Required
Installation Style	MCC / Indoor Industrial

Some third-party listings provide inconsistent generic dimensions for this product, so those figures should not be treated as certified overall dimensions.

For engineering drawings, transportation planning and cabinet fabrication, the configuration-specific mechanical drawing should be used.

The 600 mm depth is the safer general specification for the standard MCC-style configuration.

11. Weight

The model is a very large drive and has a substantial equipment weight.

One equipment listing gives a weight of approximately 2,748 lb, equivalent to roughly 1,247 kg.

Weight Parameter	Specification
Model	20G11BE630AN0NNNNN
Approx. Equipment Weight	1,247 kg
Approx. Metric Tons	1.25 metric tons
Weight in Pounds	Approx. 2,748 lb
Shipping Weight	Configuration / Packaging Dependent
Floor Loading	Must Be Evaluated
Transportation	Heavy Industrial Equipment
Lifting	Heavy-Duty Equipment Required

The shipping weight may differ from equipment-only weight because packaging, accessories and shipping materials can add weight.

For structural calculations, lifting operations and transportation, the actual shipment documentation should always be used.

12. Air-Cooled Design

The drive uses forced-air cooling.

High-power semiconductor devices generate heat during operation.

The cooling system moves air through the power section to remove heat and maintain appropriate operating temperatures.

A proper installation should provide:

• Clean cooling air
• Adequate ventilation
• Sufficient airflow
• Appropriate ambient temperature
• Correct equipment spacing
• Suitable heat removal
• Regular fan inspection

Dust accumulation is particularly important in industrial environments.

Blocked airflow can increase internal temperature and shorten the service life of power components.

13. Type 1 / IP20 Protection

The drive uses a Type 1 / IP20 configuration.

This type of protection is intended primarily for indoor industrial environments.

It should not be considered a weatherproof enclosure.

The equipment should be protected against:

• Rain
• Direct water
• Water spray
• Condensation
• Excessive dust
• Conductive contamination
• Corrosive chemicals
• Outdoor exposure

The surrounding electrical room or MCC structure therefore forms an important part of the overall environmental protection system.

14. AC Input With Precharge

The catalog configuration is associated with AC input with precharge.

The precharge circuit controls the initial charging of the DC bus when the drive is energized.

A simplified power path is:

600 VAC Three-Phase Input

↓

Input / Precharge Section

↓

DC Bus

↓

Power Inverter

↓

Variable-Frequency AC Output

↓

Industrial Motor

Precharge is especially important on large drives because the DC bus contains a substantial amount of stored energy.

Maintenance personnel must follow the correct isolation and discharge procedures before working inside the drive.

15. DC Terminals

The configuration includes DC terminals.

DC-bus connections can be relevant to certain industrial system arrangements and specialized drive architectures.

However, DC terminals should be treated as high-energy electrical connections.

The DC bus can retain hazardous energy after incoming AC power has been disconnected.

Proper isolation, discharge time and electrical safety procedures are therefore essential.

16. EMC Filtering

The drive is specified with an EMC-filtered configuration.

Variable-frequency drives use high-speed switching devices to synthesize the motor waveform.

That switching process can generate conducted and radiated electrical noise.

The EMC filtering helps manage this behavior.

However, good EMC performance depends on the complete installation.

Important factors include:

• Grounding
• Bonding
• Motor cable construction
• Cable shielding
• Cable routing
• Separation between power and signal wiring
• Motor-frame grounding
• Cabinet construction

The filter is only one part of the complete EMC design.

17. CM Jumper Removed

The CM jumper is removed in this configuration.

This is an important catalog detail.

Common-mode configuration affects the relationship between the drive, grounding system and motor system.

When replacing an existing drive, the CM configuration should be checked rather than assuming that two drives with the same voltage and current rating are electrically identical.

The complete catalog number should always be considered.

18. No Dynamic Braking

The 20G11BE630AN0NNNNN is specified with no internal dynamic-braking transistor.

Parameter	Specification
Model	20G11BE630AN0NNNNN
Dynamic Braking	None
Internal Braking Transistor	No
High-Inertia Load	Application Evaluation Required
Rapid Deceleration	Additional Braking Solution May Be Required
Regenerative Operation	Additional Engineering Required

This matters for machines with substantial rotational inertia.

During rapid deceleration, the motor can return energy toward the DC bus.

Depending on the application, engineers may need to consider:

• Longer deceleration time
• External braking equipment
• Mechanical braking
• Regenerative solutions
• Controlled stopping profiles

19. Blank / No-HIM Configuration

The model is configured as Blank / No HIM.

HIM means Human Interface Module.

The absence of a local keypad does not mean that the drive lacks control capability.

In large industrial facilities, the drive may be installed inside an electrical room and controlled remotely through:

• PLC
• HMI
• SCADA
• DCS
• Ethernet/IP
• Plant automation system

This arrangement is particularly useful where local operator access to the drive cabinet is unnecessary.

20. Embedded Ethernet/IP

Embedded Ethernet/IP is one of the most useful features of the PowerFlex 755 platform.

The drive can exchange information with a plant automation system.

Typical information can include:

• Start command
• Stop command
• Speed reference
• Actual speed
• Output current
• Drive status
• Fault status
• Alarm status
• Diagnostic information
• Parameter information

This allows the drive to become part of a centralized control architecture rather than operating as an isolated motor controller.

21. Typical Pump Applications

The 20G11BE630AN0NNNNN is well suited to large pump applications.

Typical uses include:

• Raw-water pumps
• Cooling-water pumps
• Industrial circulation pumps
• Booster pumps
• Mine dewatering pumps
• Wastewater pumps
• Process pumps
• Water-transfer systems

Variable-speed control allows the pump to operate according to process demand.

Instead of running continuously at full speed, the motor can be slowed when lower flow is required.

This can provide meaningful energy savings in appropriate variable-torque systems.

22. Fan Applications

Large industrial fans can require hundreds of horsepower.

Possible applications include:

• Mine ventilation
• Industrial exhaust
• Process ventilation
• Dust collection
• Furnace ventilation
• Cooling systems
• Large air-handling systems

The drive allows fan speed to be adjusted according to actual process requirements.

23. Blower Applications

Large blowers are another suitable application.

Examples include:

• Wastewater aeration
• Process-air systems
• Industrial ventilation
• Pneumatic conveying
• Combustion-air systems
• Drying equipment
• Process blowers

For continuous blower operation, thermal management and correct duty selection are especially important.

24. Conveyor Applications

Large conveyors frequently have high mechanical inertia.

Controlled acceleration can reduce mechanical stress on the machine.

Instead of applying full motor speed immediately, the drive can increase speed according to a programmed acceleration profile.

This can reduce stress on:

• Belts
• Gearboxes
• Couplings
• Shafts
• Bearings
• Conveyor structures

For heavily loaded conveyors, the Heavy-Duty rating should be evaluated carefully.

25. Mining Applications

Mining operations frequently require high-power motor control.

Potential applications include:

• Mine dewatering
• Ventilation
• Conveyors
• Material handling
• Processing equipment
• Large pumps
• Auxiliary machinery

The high current capacity of the 20G11BE630AN0NNNNN makes it more suitable for large mining equipment than compact drive families.

26. Cement Plant Applications

Cement plants use many large motors.

Potential applications include:

• Large process fans
• Exhaust fans
• Blowers
• Cooling systems
• Material conveyors
• Dust-collection systems
• Large pumps
• Auxiliary process equipment

The drive’s high-power architecture and network connectivity are useful in centralized plant-control systems.

27. Water and Wastewater Applications

Water and wastewater facilities often operate large pumps and blowers continuously.

The drive can be applied to:

• Intake pumps
• Transfer pumps
• Distribution pumps
• Wastewater pumps
• Aeration blowers
• Flood-control pumps
• Industrial circulation systems

Variable-speed control can help match motor output to actual process demand.

28. Steel and Metal Processing

Large metal-processing plants also have many high-power auxiliary motor applications.

Possible applications include:

• Cooling-water pumps
• Process fans
• Ventilation systems
• Blowers
• Conveyors
• Material-handling equipment
• Auxiliary process machinery

The 630 A capacity provides considerable motor-control capability for these applications.

29. Main Product Advantages

29.1 High 630 A Current Rating

The 630 A output capacity makes this model appropriate for large industrial motors.

It is substantially larger than compact VFD products intended for machine-level applications.

29.2 Up to 800 HP Light-Duty Capability

The model is commonly specified for approximately 800 HP Light Duty, providing considerable capacity for large variable-torque loads.

29.3 700 HP Normal-Duty Capability

The approximately 700 HP Normal-Duty rating makes the drive useful for general industrial motor applications.

29.4 600 HP Heavy-Duty Capability

The approximately 600 HP Heavy-Duty rating provides a substantial operating range for applications requiring greater torque and overload capability.

29.5 600 VAC Industrial Voltage

The 600 VAC class makes the model suitable for large industrial power systems.

29.6 Frame 9 High-Power Construction

Frame 9 construction provides the physical platform required for high-power switching and cooling components.

29.7 Embedded Ethernet/IP

Network integration allows the drive to communicate with centralized industrial control systems.

29.8 Forced-Air Cooling

Air cooling provides a practical thermal-management solution for large indoor industrial installations.

29.9 EMC Filtering

The filtered configuration helps support electromagnetic compatibility when used with appropriate installation practices.

29.10 No-HIM Configuration

The blank configuration is useful for centralized PLC/HMI/SCADA control architectures.

29.11 MCC-Style Packaging

The 600 mm deep MCC-style package is suitable for centralized electrical rooms and industrial motor-control installations.

30. Energy-Saving Potential

One of the major reasons for using a variable-frequency drive is the ability to regulate motor speed instead of operating the motor continuously at full speed.

This can be especially valuable in:

• Pumps
• Fans
• Blowers
• Cooling systems

For variable-torque applications, reducing speed can significantly reduce power demand.

For example:

Full-Speed Operation

→ Higher flow

→ Higher power consumption

versus:

Reduced-Speed Operation

→ Lower flow

→ Lower motor power

The actual energy savings depend on:

• Operating hours
• Load profile
• Motor efficiency
• Pump or fan efficiency
• System resistance
• Required process output
• Control strategy

31. Centralized Automation Architecture

A typical installation can be arranged as:

Plant PLC / Automation Controller

↓

Ethernet/IP Network

↓

PowerFlex 755

↓

630 A-Class Motor

↓

Pump / Fan / Conveyor / Blower

↓

Industrial Process

This arrangement allows operators to monitor and control the motor without needing to access the drive cabinet directly.

32. Maintenance Considerations

A drive of this size requires a proper preventive-maintenance program.

Important inspection points include:

• Cooling fans
• Air passages
• Power terminals
• Cable connections
• Grounding
• Cabinet cleanliness
• Ambient temperature
• Fault history
• Alarm history
• Network communication
• Motor condition
• Motor insulation
• Mechanical coupling
• Bearings

Cooling should receive particular attention.

Industrial dust can accumulate around ventilation paths and reduce cooling performance.

Regular cleaning and inspection can help maintain stable operating temperatures.

33. Thermal Management

The drive produces heat during normal operation.

When several high-power drives are installed in the same electrical room, the total heat load can become significant.

The electrical room should therefore be designed around:

• Total drive heat generation
• HVAC capacity
• Airflow
• Ambient temperature
• Equipment spacing
• Air circulation
• Exhaust arrangement

Hot exhaust air should not simply be recirculated back through the cooling intake.

34. Electrical Installation

A 630 A drive represents a significant electrical load.

The complete installation should be evaluated for:

• Incoming feeder capacity
• Short-circuit rating
• Protective devices
• Busbar capacity
• Cable ampacity
• Motor cable sizing
• Grounding
• EMC
• Harmonics
• Motor compatibility
• Electrical clearances

The drive should be treated as one component of the overall electrical distribution system.

35. Motor Selection

The motor should be evaluated against the drive’s electrical characteristics.

Motor Parameter	Importance
Motor Voltage	Must match the applicable drive voltage class
Motor Full-Load Current	Primary drive-sizing parameter
Motor Horsepower	Determines approximate power level
Motor Frequency	Important for speed control

Industrial Ventilation	LD / ND	Variable-speed operation
High-Inertia Machine	HD	Higher overload requirement

37. Five Recommended Same-Series / Related Models

The following models are useful for comparing the 20G11BE630AN0NNNNN with other high-power PowerFlex 755 configurations in the same 600 VAC family.

No.	Model	Voltage	Current	LD Rating	ND Rating	HD Rating	Frame	Cooling
1	20G11BE595AN0NNNNN	600 VAC	595 A	700 HP	600 HP	500 HP	9	Air Cooled
2	20G11BE760AN0NNNNN	600 VAC	760 A	900 HP	800 HP	700 HP	9	Air Cooled
3	20G11BE825AN0NNNNN	600 VAC	825 A	950 HP	900 HP	750 HP	9	Air Cooled
4	20G11BE900AN0NNNNN	600 VAC	900 A	1,000 HP	950 HP	800 HP	9	Air Cooled
5	20G11BE980AN0NNNNN	600 VAC	980 A	1,100 HP	1,000 HP	900 HP	9	Air Cooled

These related models provide a practical progression around the 630 A class. The 595 A model is the nearest lower-current option, while the 760 A, 825 A, 900 A and 980 A configurations provide increasing capacity. The related catalog family includes these configurations.

38. Same-Series Parameter Comparison

Model	Voltage	Output Current	LD	ND	HD	Frame	Depth
20G11BE595AN0NNNNN	600 VAC	595 A	700 HP	600 HP	500 HP	9	Approx. 600 mm
20G11BE630AN0NNNNN	600 VAC	630 A	800 HP	700 HP	600 HP	9	Approx. 600 mm
20G11BE760AN0NNNNN	600 VAC	760 A	900 HP	800 HP	700 HP	9	Approx. 600 mm
20G11BE825AN0NNNNN	600 VAC	825 A	950 HP	900 HP	750 HP	9	Approx. 600 mm

20G11BE980AN0NNNNN	600 VAC	980 A	1,100 HP	1,000 HP	900 HP	9	Approx. 600 mm

The 630 A configuration sits between the 595 A and 760 A versions, making it a useful choice when the 595 A rating is too small but a 760 A drive would provide unnecessary excess capacity.

39. Mechanical Comparison of Related Models

This means that two PowerFlex 755 drives with the same voltage and current rating can still have meaningful configuration differences.

When replacing the equipment, the entire catalog number should be reviewed.

47. Why the No-HIM Configuration Can Be Useful

A no-HIM drive is especially useful in centralized industrial-control environments.

A typical system can be arranged as:

Operator HMI

↓

PLC

↓

Ethernet/IP

↓

PowerFlex 755

↓

630 A-Class Motor

↓

Industrial Process

This arrangement keeps the operator interface separate from the high-power drive equipment.

48. Energy Management

Large motors can account for a substantial portion of industrial electrical consumption.

Variable-speed control can reduce unnecessary motor speed in applications where full speed is not continuously required.

This is especially attractive for:

• Pumps
• Fans
• Blowers
• Cooling systems

For variable-torque equipment, speed reduction can result in a disproportionately large reduction in power consumption.

However, actual savings must be calculated from the real process operating curve.

49. Maintenance Strategy

A practical maintenance program should include regular checks of:

Cooling Fans

Verify proper operation and airflow.

Ventilation Paths

Remove accumulated dust and debris.

Power Connections

Check for looseness, overheating or abnormal discoloration.

Grounding

Verify grounding and bonding integrity.

Communication

Check Ethernet/IP communication and network status.

Fault History

Look for repeated faults instead of simply resetting them.

Motor

Inspect motor condition, insulation, bearings and mechanical connections.

Environment

Monitor temperature, humidity, dust and contamination.

50. Thermal Management

The 630 A power class means that thermal management should be taken seriously.

For a large electrical room containing multiple drives, the total heat generation can be significant.

The room design should therefore consider:

• Total installed drive power
• Heat losses
• HVAC capacity
• Airflow
• Ambient temperature
• Equipment spacing
• Exhaust air
• Cooling-air supply

Poor thermal design can reduce equipment reliability even when the drive itself is correctly selected.

51. Mechanical Handling

The approximate 1,247 kg equipment weight makes transportation an important engineering consideration.

Before installation, the project should evaluate:

• Floor loading
• Door dimensions
• Transport route
• Forklift capacity
• Crane capacity
• Lifting equipment
• Lifting points
• Final installation position
• Maintenance clearance
• Future replacement access

This is particularly important for a Frame 9 high-power drive.

52. Electrical Installation Planning

A 630 A VFD requires careful electrical planning.

The engineering design should include:

• Incoming feeder sizing
• Circuit protection
• Short-circuit considerations
• Busbar sizing
• Cable sizing
• Grounding
• EMC
• Motor cable selection
• Harmonic considerations
• Cabinet ventilation
• Electrical clearance

The complete electrical system should be designed around the actual installation rather than simply around the drive’s nameplate current.

55. Overall Product Assessment

The Allen-Bradley 20G11BE630AN0NNNNN is a high-power PowerFlex 755 AC drive designed for demanding industrial motor-control applications.

Its most important electrical characteristics are 600 VAC, three-phase operation, 630 A output current, approximately 800 HP Light Duty, 700 HP Normal Duty and 600 HP Heavy Duty capability.

The Frame 9 construction, forced-air cooling and 600 mm deep MCC-style package make it suitable for large centralized electrical installations.

The embedded Ethernet/IP capability makes the drive especially useful where the motor needs to be integrated into a PLC, HMI, SCADA or other industrial automation system.

The blank/no-HIM configuration is appropriate for installations where operators control the equipment remotely instead of operating the drive from a local keypad.

The EMC-filtered configuration and CM jumper removed arrangement are also important details when integrating the drive into the plant’s grounding, motor-cable and EMC architecture.

The model is well suited to large centrifugal pumps, fans, blowers, conveyors, mining systems, cement plants, water-treatment equipment, wastewater facilities, material-handling systems and other high-power industrial machinery.

The approximate 1,247 kg equipment weight means that transportation, lifting, floor loading and mechanical installation must be planned carefully.

The 600 mm package depth is useful for preliminary layout planning, while the final height and width should be determined from the actual mechanical configuration.

From an application standpoint, this model is especially attractive when the motor is in the approximate 600–800 HP range, depending on the duty category.

For a 600 HP heavy-duty motor, the model offers a substantial current margin within its stated duty class.

For a 700 HP normal-duty motor, it provides a strong match for large general-purpose industrial applications.

For an 800 HP light-duty motor, it is particularly suitable for variable-torque applications such as large pumps, fans and blowers.

The original 20G11BE630AN0NNNNN is a discontinued configuration, so the 20G11BE630JN0NNNNN should be considered for replacement projects.

In practical terms, the product can be summarized as a 600 VAC, 630 A, Frame 9 PowerFlex 755 high-power AC drive with approximately 520 kW normal-duty output class, 800 HP Light-Duty capability, 700 HP Normal-Duty capability, 600 HP Heavy-Duty capability, forced-air cooling, IP20/Type 1 protection, 600 mm MCC-style construction, embedded Ethernet/IP, EMC filtering, CM jumper removed and no local HIM.
