The horsepower-to-kilowatt figures are approximate conversions using 1 HP ≈ 0.746 kW. They are useful for general engineering comparison, but actual drive selection should be based primarily on motor nameplate current, duty cycle, overload requirement and application characteristics.

The published catalog configuration identifies the package as approximately 600 mm deep. Exact overall height and width are configuration-dependent and should not be fabricated from a generic frame-size assumption.

For the same reason, the weight should be treated carefully. For preliminary plant-layout purposes, this equipment can reasonably be regarded as being in the 1,300–1,500 kg class, but the final shipping or installed weight should be taken from the specific mechanical configuration.

---

4. Electrical Rating

The most important characteristic of the 20G11BE1K4AN0NNNNN is its extremely high current capability.

The drive is rated at approximately 1,430 A and is designed for a 600 VAC three-phase supply. The available duty ratings are:

Duty	Horsepower	Approx. kW
Light Duty	1,500 HP	1,119 kW
Normal Duty	1,400 HP	1,044 kW
Heavy Duty	1,250 HP	933 kW

These ratings place the model firmly in the very-high-power industrial category.

It is not intended for ordinary small machinery.

Instead, it is intended for large motor loads where the motor itself can require hundreds or more than one thousand horsepower.

---

5. 600 VAC Three-Phase Design

The 600 VAC input class is an important feature of this model.

Many industrial variable-frequency drives are available in 400 VAC, 480 VAC or similar voltage classes.

The 20G11BE1K4AN0NNNNN belongs to the 600 VAC class, making it suitable for industrial electrical systems designed around this voltage.

For large motors, higher operating voltage can help keep the required current within a practical range.

Nevertheless, the 1,430 A output rating demonstrates just how large the intended motor loads are.

This is a drive designed for major process equipment rather than small production machines.

---

6. Very High 1,430 A Output Capacity

The 1,430 A output rating is one of the defining features of the model.

At this current level, the drive can be used for motors approaching or exceeding the 1 MW range, depending on motor voltage, efficiency, power factor and duty requirements.

The three main ratings are:

• 1,500 HP Light Duty
• 1,400 HP Normal Duty
• 1,250 HP Heavy Duty

The Heavy-Duty rating is especially important when the application has greater overload requirements or demanding acceleration characteristics.

The actual selection should always start with the motor’s rated current rather than simply matching horsepower.

---

7. Frame 10

The 20G11BE1K4AN0NNNNN uses Frame 10 construction.

Frame 10 is associated with the larger PowerFlex 755 power range.

The physical structure needs to accommodate substantial power semiconductors, bus components, high-current conductors and forced-air cooling equipment.

The result is equipment that is physically much larger and heavier than compact PowerFlex drives.

This should be considered during:

• Electrical-room planning
• MCC design
• Transportation
• Installation
• Floor loading
• Lifting
• Maintenance
• Replacement planning

---

8. Air-Cooled Construction

The drive uses forced-air cooling.

At a power level of approximately 1 MW and above, heat management becomes an important part of the overall installation.

The cooling system must continuously remove heat from the power electronics.

A properly designed installation should therefore provide adequate:

• Air circulation
• Ventilation
• Room cooling
• Service clearance
• Filter maintenance
• Fan maintenance

The drive should not be installed in an area where hot air from other equipment is continuously recirculated.

---

9. Type 1 / IP20 Protection

The model uses a Type 1 / IP20 industrial enclosure configuration.

This is appropriate for suitable indoor electrical installations.

It is not a weatherproof or water-resistant enclosure.

The equipment should be protected from:

• Rain
• Direct water spray
• Condensation
• Excessive humidity
• Conductive dust
• Corrosive gases
• Chemical contamination
• Excessive airborne contamination

For harsh environments, additional environmental protection may be required.

---

10. 600 mm Deep MCC-Style Package

The model is specified as a 600 mm deep MCC-style configuration.

This makes it suitable for centralized industrial electrical rooms and motor-control installations.

Mechanical Parameter	Specification
Model	20G11BE1K4AN0NNNNN
Frame	10
Package Style	MCC Style
Nominal Depth	Approx. 600 mm
Width	Configuration Dependent
Height	Configuration Dependent
Enclosure	Type 1
Protection	IP20
Cooling	Forced Air
Installation	Indoor Industrial Electrical Room
Floor Loading	Must Be Evaluated
Lifting	Heavy Mechanical Handling Required
Service Clearance	Required
Cable Clearance	Required

The 600 mm depth should not be treated as the complete installation footprint.

Large motor cables can require considerable bending space.

There also needs to be enough room for ventilation and maintenance.

---

11. Dimensions

Because this is a large packaged drive, dimensions should be handled differently from compact DIN-rail or small cabinet-mounted drives.

Dimension	Specification
Model	20G11BE1K4AN0NNNNN
Depth	Approx. 600 mm
Width	Configuration Dependent
Height	Configuration Dependent
Complete Installation Footprint	Configuration Dependent
Cable Bending Space	Required
Service Clearance	Required
Door Clearance	Required
Ventilation Clearance	Required

The 600 mm depth is the useful package reference.

The exact height and width should be taken from the final mechanical drawing for the particular packaged configuration.

For engineering documentation, it is preferable to state “configuration dependent” rather than insert an unverified dimension.

---

12. Weight

The 20G11BE1K4AN0NNNNN is heavy industrial equipment.

A reasonable preliminary engineering classification is approximately 1,300–1,500 kg.

Weight Parameter	Specification
Model	20G11BE1K4AN0NNNNN
Planning Weight	Approx. 1,300–1,500 kg
Final Equipment Weight	Configuration Dependent
Shipping Weight	May Be Higher
Floor Loading	Must Be Evaluated
Lifting Method	Heavy-Duty Mechanical Handling
Transportation	Industrial Equipment Handling
Installation	Crane / Suitable Lifting Equipment Recommended

The planning range should not be used as a certified shipping weight.

For final transportation or structural calculations, the actual configuration-specific weight should be used.

---

13. AN0 Configuration

The AN0 configuration indicates that the drive is supplied without a local HIM.

HIM means Human Interface Module.

This means the drive is well suited to centralized control architectures.

Instead of relying on a local keypad, operators can interact with the drive through:

• PLC
• HMI
• SCADA
• DCS
• Engineering workstation
• Ethernet/IP network

This configuration is particularly practical for large automated plants.

---

14. No Local HIM

The lack of a local HIM can be an advantage in centralized installations.

For example, imagine a large water-treatment facility containing dozens of pumps.

Operators may already have a central control room.

There is little practical benefit in requiring an operator to walk to each individual drive just to change a speed reference.

A centralized HMI can provide:

• Start/stop control
• Speed reference
• Current monitoring
• Fault indication
• Alarm indication
• Status monitoring
• Process feedback

This makes the AN0 configuration particularly suitable for large automated installations.

---

15. Embedded Ethernet/IP

The PowerFlex 755 platform supports embedded Ethernet/IP communication.

This allows the drive to participate in a larger automation network.

Typical information exchanged between the control system and drive can include:

• Start command
• Stop command
• Speed reference
• Actual speed
• Output current
• Drive status
• Fault status
• Alarm information
• Process-related parameters
• Diagnostic information

This is particularly useful when the drive is part of a large coordinated production system.

---

16. AC Input With DC Terminals

The drive uses an AC input arrangement with DC terminals.

The simplified electrical power path is:

600 VAC Three-Phase Supply

↓

Input Section

↓

Precharge / DC Bus

↓

Inverter Power Section

↓

Variable-Frequency AC Output

↓

Large Industrial Motor

The inverter section changes the electrical output frequency and voltage according to the motor-control requirements.

This enables controlled motor acceleration, deceleration and variable-speed operation.

---

17. Variable-Speed Control

The primary purpose of the drive is to control the operating speed of a large AC motor.

Without variable-speed control, an AC motor generally operates close to its rated speed when connected directly to the electrical supply.

A VFD allows the motor to operate at different speeds.

This provides substantial process flexibility.

For example:

A large pump can reduce speed when less water is required.

A fan can reduce speed when ventilation demand falls.

A conveyor can operate at a controlled production speed.

A blower can adjust its output according to process pressure.

---

18. Controlled Acceleration

Large motors can have substantial inertia.

Directly starting a large motor can result in significant electrical and mechanical stress.

The drive can provide a controlled acceleration ramp.

Instead of immediately applying full-speed operation, the motor can gradually accelerate.

This can help reduce mechanical shock to:

• Couplings
• Gearboxes
• Shafts
• Bearings
• Belts
• Conveyor systems
• Pump systems

The actual acceleration profile should be determined according to the motor and mechanical load.

---

19. Controlled Deceleration

The same principle applies when stopping.

A large rotating load can store considerable kinetic energy.

If the process requires controlled stopping, the drive can manage the deceleration profile.

However, this particular configuration does not include an internal dynamic-braking transistor.

Therefore, applications requiring aggressive deceleration should be evaluated separately.

Possible solutions can include:

• Longer deceleration time
• Mechanical braking
• External braking equipment
• Regenerative technology

The appropriate method depends on the load inertia and stopping requirements.

---

20. Dynamic Braking

Parameter	Specification
Model	20G11BE1K4AN0NNNNN
Dynamic Braking	None
Internal Braking Transistor	None
High-Inertia Application	Engineering Evaluation Required
Rapid Deceleration	Additional Solution May Be Required
Regenerative Operation	Application Dependent

This is an important consideration during drive selection.

A motor can be perfectly matched to the current rating while the application may still require additional braking capability.

Therefore, drive selection should consider both running current and dynamic behavior.

---

21. EMC Filter

The model is configured with an EMC filter.

Electromagnetic compatibility becomes increasingly important as the size and switching power of the drive increases.

A VFD switches power electronics at high speed.

This switching can create electrical noise.

The EMC filter helps manage conducted electromagnetic disturbances.

However, the filter is only one part of the complete EMC design.

The installation should also consider:

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

---

22. CM Jumper Removed

The model is specified with the CM jumper removed.

This is an important configuration detail.

Common-mode electrical behavior can influence:

• Leakage current
• Grounding behavior
• EMC performance
• System compatibility

Therefore, when replacing an existing drive, it is important to compare the complete catalog number instead of selecting a replacement based only on voltage and current.

---

23. Large Pump Applications

Large pumps are one of the strongest application areas for this drive.

Possible applications include:

• Water-transfer pumps
• Cooling-water pumps
• Mine dewatering pumps
• Raw-water pumps
• Industrial process pumps
• High-capacity wastewater pumps
• Flood-control pumps
• Large circulation pumps

Variable-speed operation can allow the pump to match output to actual process requirements.

This can reduce unnecessary throttling and may provide meaningful energy savings in suitable variable-torque systems.

---

24. Large Fan Applications

Large industrial fans can consume very large amounts of electricity.

The drive can be applied to:

• Mine ventilation fans
• Exhaust fans
• Process ventilation
• Cooling fans
• Combustion-air fans
• Dust-collection fans
• Industrial air-handling systems

Variable-speed control allows airflow to be adjusted without requiring the motor to remain at full speed continuously.

---

25. Large Blower Applications

The model is also suitable for very large blower systems.

Potential applications include:

• Aeration blowers
• Process-air blowers
• Pneumatic conveying
• Combustion-air systems
• Industrial ventilation
• Chemical process air
• Wastewater aeration

Large blowers often operate for long periods, making controllability and energy management particularly important.

---

26. Mining Applications

Mining is another major application area.

Large mining operations use extremely powerful motors for:

• Conveyors
• Ventilation
• Dewatering
• Material handling
• Crushing
• Processing
• Auxiliary systems

A 1,430 A drive provides enough capacity for very large motor systems.

However, mining environments can be challenging.

Dust, vibration, temperature changes and difficult maintenance access should all be considered when installing high-power electrical equipment.

---

27. Cement Industry Applications

Cement plants contain many large motors.

Typical applications include:

• Large process fans
• Exhaust fans
• Blowers
• Conveyors
• Cooling systems
• Pumps
• Material-handling equipment

The PowerFlex 755 platform is well suited to applications where large motors need to be integrated into a centralized automation system.

---

28. Steel and Metal Processing

Large metal-processing facilities can also require high-power motor control.

Potential applications include:

• Large cooling-water pumps
• Fans
• Blowers
• Conveyors
• Material handling
• Process auxiliaries
• Ventilation systems

The high current rating makes the 20G11BE1K4AN0NNNNN suitable for motor loads that exceed the capacity of smaller drive frames.

---

29. Water and Wastewater Applications

Large water infrastructure can require motors in the hundreds or thousands of horsepower.

Potential applications include:

• Intake pumps
• Transfer pumps
• Wastewater pumps
• Flood-control pumping
• Industrial water systems
• Cooling-water systems
• High-capacity treatment systems

Variable-speed operation can help match pumping output to changing process conditions.

---

30. Conveyor Applications

Large conveyors are another important application.

A heavily loaded conveyor can have considerable mechanical inertia.

Controlled acceleration can reduce sudden mechanical stress.

The drive can help provide a smooth acceleration profile.

This can reduce stress on:

• Conveyor belts
• Gearboxes
• Couplings
• Shafts
• Bearings
• Mechanical structures

For very demanding conveyor systems, the complete torque and acceleration requirements must be calculated.

---

31. Material Handling

Large material-handling systems can use high-power AC motors for:

• Conveyors
• Hoisting-related auxiliary systems
• Crushers
• Feed systems
• Bulk material transportation

The drive can provide controlled speed and acceleration, making it useful where process throughput needs to be adjusted according to production requirements.

---

32. Main Advantages

32.1 Extremely High Current Capacity

The 1,430 A rating is the primary advantage of this model.

It enables the drive to control extremely large industrial motors.

---

32.2 Very High Horsepower Capability

With ratings up to approximately 1,500 HP Light Duty, the drive belongs to the highest-power portion of the PowerFlex 755 range.

---

32.3 600 VAC Voltage Class

The 600 VAC class is suitable for large industrial electrical systems.

---

32.4 1,400 HP Normal-Duty Rating

The Normal-Duty rating of approximately 1,400 HP provides substantial continuous-duty capacity.

---

32.5 1,250 HP Heavy-Duty Rating

The approximately 1,250 HP Heavy-Duty rating makes the model suitable for demanding applications with higher overload requirements.

---

32.6 PowerFlex 755 Platform

The PowerFlex 755 platform is designed for advanced industrial motor control and automation integration.

This makes the model more suitable for sophisticated process systems than a basic standalone VFD.

---

32.7 Embedded Ethernet/IP

Network integration makes it easier to incorporate the drive into centralized automation architectures.

---

32.8 No-HIM Configuration

The AN0 configuration is particularly appropriate when operator control is already provided by a central HMI or SCADA system.

---

32.9 Air-Cooled Design

Forced-air cooling provides a practical approach for large industrial electrical rooms where adequate ventilation is available.

---

32.10 EMC-Filtered Configuration

The EMC-filtered configuration supports electrical-noise management in properly designed installations.

---

33. Energy-Saving Potential

Variable-frequency drives can offer substantial energy-saving opportunities in suitable applications.

This is particularly true for:

• Centrifugal pumps
• Fans
• Blowers

For variable-torque loads, reducing motor speed can substantially reduce power consumption.

For example, a pump does not necessarily need to operate at maximum speed when process demand is low.

Instead of running the motor at full speed and controlling flow mechanically, the drive can reduce motor speed.

The actual energy savings depend on:

• Motor efficiency
• Pump or fan efficiency
• System resistance
• Operating hours
• Process demand
• Load profile
• Control strategy

Therefore, energy savings should be calculated for the specific installation rather than assumed.

---

34. Automation Advantages

The 20G11BE1K4AN0NNNNN is well suited to centralized automation.

A typical system can be arranged as:

Plant Control System

↓

Ethernet/IP Network

↓

PowerFlex 755

↓

1,400 HP-Class Motor

↓

Process Equipment

This arrangement allows operators to monitor and control the motor from a central location.

It also allows the drive to exchange status and diagnostic information with the automation system.

---

35. Maintenance Advantages

Although this is a large and complex drive, centralized monitoring can simplify plant-wide maintenance.

Operators can potentially monitor:

• Drive status
• Motor current
• Speed
• Faults
• Alarms
• Operating conditions
• Communication status

This can reduce the need for technicians to physically inspect every drive for basic operating information.

However, physical inspection and preventive maintenance remain necessary.

---

36. Maintenance Considerations

The high power level means preventive maintenance is especially important.

Maintenance programs should consider:

• Cooling fans
• Airflow
• Electrical connections
• Cable terminations
• Grounding
• Contamination
• Cabinet temperature
• Fault history
• Communication status
• Motor condition
• Insulation condition

The electrical room should also be kept clean.

Dust accumulation can reduce cooling performance and increase the risk of electrical contamination.

---

37. Thermal Management

A drive of this size produces significant heat.

When multiple large drives are installed in the same room, the combined thermal load can be substantial.

The electrical room should therefore be designed with:

• Adequate HVAC capacity
• Sufficient ventilation
• Appropriate airflow
• Controlled ambient temperature
• Correct cabinet spacing
• Clean cooling-air supply

Cooling fans should be included in the maintenance schedule.

---

38. Mechanical Handling

The approximate 1,300–1,500 kg class planning weight means that mechanical handling should be planned before the equipment arrives.

Consider:

• Truck unloading
• Factory entrance dimensions
• Door dimensions
• Floor capacity
• Forklift capacity
• Crane access
• Lifting points
• Installation position
• Maintenance access
• Future replacement path

A drive this large should never be treated like a small cabinet component.

---

39. Electrical Installation Requirements

At approximately 1,430 A, electrical installation requires detailed engineering.

Important factors include:

• Incoming feeder capacity
• Circuit protection
• Short-circuit current
• Busbar sizing
• Cable ampacity
• Motor cable sizing
• Grounding
• Termination hardware
• Heat dissipation
• EMC
• Motor compatibility
• Harmonic considerations
• Installation clearances

The drive should be coordinated with the complete electrical distribution system.

---

40. Motor Selection

A common mistake in VFD selection is choosing a drive based solely on motor horsepower.

For a drive this large, the motor nameplate should be reviewed carefully.

Important motor parameters include:

• Rated voltage
• Rated current
• Rated frequency
• Rated horsepower
• Base speed
• Full-load current
• Power factor
• Efficiency
• Overload requirement
• Starting torque
• Inertia
• Cooling method

The drive should be selected according to the actual motor and application.

---

48. Why Choose the 20G11BE1K4AN0NNNNN?

The strongest reason to choose this model is its combination of 600 VAC operation and 1,430 A output capacity.

For applications requiring approximately 1,400 HP, a smaller drive may not provide enough current or overload capacity.

The model also offers the advantages of the PowerFlex 755 platform.

It is designed for industrial automation rather than simple standalone motor control.

Its Ethernet/IP integration makes it suitable for centralized control.

Its AN0 configuration makes it particularly appropriate where local operator interfaces are unnecessary.

Its Frame 10 construction provides the physical architecture required for this very high power level.

49. When a Smaller Model May Be Better

Despite its capabilities, the 20G11BE1K4AN0NNNNN should not be selected simply because it is powerful.

If the motor only requires 500 A, for example, a 1,430 A drive would be unnecessarily large.

A smaller PowerFlex 755 configuration may provide:

• Lower equipment cost
• Smaller footprint
• Lower installation requirements
• Easier handling
• Reduced cooling requirements
• More practical maintenance

Therefore, the best drive is not necessarily the largest drive.

The correct selection is the drive that matches the motor and process requirements with appropriate operating margin.

52. Final Product Assessment

The Allen-Bradley 20G11BE1K4AN0NNNNN is a very high-power PowerFlex 755 AC drive intended for demanding industrial motor-control applications.

Its 1,430 A output capacity, 600 VAC three-phase input, 1,500 HP Light-Duty rating, 1,400 HP Normal-Duty rating and 1,250 HP Heavy-Duty rating place it among the large-capacity industrial drive configurations.

The Frame 10 construction, forced-air cooling and MCC-style package are appropriate for large electrical-room installations.

The AN0 configuration without a local HIM is especially suitable for centralized automation systems where the drive is controlled through a PLC, HMI, SCADA or other plant-level control system.

The combination of embedded Ethernet/IP, EMC filtering, high current capability and PowerFlex 755 functionality makes it a strong choice for large process installations.

Typical applications include large pumping stations, mine dewatering, large ventilation systems, industrial blowers, cement plants, mining conveyors, water-treatment facilities, wastewater systems, steel plants and large material-handling equipment.

The drive is particularly attractive when the application requires a very large motor and controlled variable-speed operation.

At the same time, its large physical size, substantial weight, cooling requirements and high-current electrical installation requirements mean that it should be treated as major industrial equipment rather than as a conventional compact VFD.

For mechanical planning, the 600 mm package depth can be used as the primary reference, while exact height and width should be taken from the final configuration. The weight should be considered approximately 1,300–1,500 kg class for preliminary planning, with the final configuration-specific weight used for transportation, lifting and structural calculations.

In practical terms, the 20G11BE1K4AN0NNNNN is best described as a very-high-power 600 VAC PowerFlex 755 drive for approximately 1.25–1.5 MW-class industrial motor applications, with centralized automation capability and a no-HIM configuration.
