20G11BC1K0AN0NNNNN — Detailed Product Specifications, Product Introduction, Applications, Advantages and Related Model Recommendations

1. Product Overview

The 20G11BC1K0AN0NNNNN is a high-power PowerFlex 755 AC drive designed for large industrial motor-control applications.

It is an air-cooled, three-phase, 400 VAC AC drive with a very high 1,040 A output-current rating. The drive is rated at approximately 630 kW for Low Duty, 560 kW for Normal Duty and 500 kW for Heavy Duty.

The unit uses a Frame 9 construction and is configured as a 600 mm deep MCC-style drive with a Type 1 / IP20 enclosure arrangement. It includes embedded EtherNet/IP, AC input with DC terminals, EMC filtering, and a removed CM jumper configuration. The catalog number also indicates no dynamic-braking transistor and a blank configuration without a HIM keypad.

This is a substantially larger drive than conventional machine-level VFDs. It is intended for large pumps, fans, compressors, conveyors, material-handling systems, process machinery and other applications where motor power reaches several hundred kilowatts.

The product is also a discontinued configuration, with the same catalog number listed as discontinued and a direct replacement configuration identified. For projects involving an existing unit, this makes catalog-number verification particularly important before purchasing or specifying a replacement.

---

4. Catalog Number Interpretation

The catalog number 20G11BC1K0AN0NNNNN contains a large amount of configuration information.

Catalog Number Section	General Meaning
20G	PowerFlex 750-series architecture
11	PowerFlex 755 configuration
B	400 VAC class
C	Air-cooled / MCC-style configuration
1K0	1,040 A current class
A	AC input configuration
N	CM jumper removed / specified configuration
0	No dynamic-braking transistor
NNNNN	No additional selected options / blank HIM configuration

The complete catalog number should always be treated as one configuration rather than interpreting each character independently.

The particularly important characteristics of this model are the 400 VAC rating, 1,040 A output, Frame 9 construction, 600 mm MCC-style cabinet depth, embedded EtherNet/IP, DC terminals, EMC filter, no dynamic-braking transistor and no HIM.

---

5. Electrical Rating

The 1,040 A output-current rating is the most striking characteristic of this drive.

At this current level, the drive is designed for very large motors and high-power industrial equipment.

Its three main power ratings are:

Duty Classification	Rated Power
Low Duty	630 kW
Normal Duty	560 kW
Heavy Duty	500 kW

The Normal Duty rating of 560 kW makes the drive appropriate for large continuous-duty machines where the motor operates with a relatively stable load.

The Heavy Duty rating of 500 kW is more appropriate where the machine requires greater overload capability or experiences more demanding acceleration and torque conditions.

The Low Duty rating can be relevant to applications where the load profile is less demanding and the drive can operate under the corresponding duty conditions.

---

6. 400 VAC Three-Phase Configuration

The drive is configured for a 400 VAC, three-phase electrical system.

This voltage class is widely used in industrial power-distribution systems, particularly in large industrial facilities.

At a power level of several hundred kilowatts, the drive’s 1,040 A current capacity places it firmly in the large-drive category.

Applications with this kind of power demand generally require dedicated electrical distribution, substantial motor cabling, suitable protection equipment and carefully engineered cabinet ventilation.

The electrical installation should therefore be designed as a complete system rather than treating the drive as an isolated component.

---

7. High-Power Industrial Architecture

The 20G11BC1K0AN0NNNNN is not a compact machine inverter.

It is a large industrial drive intended to be integrated into an MCC-style electrical installation.

The Frame 9 architecture provides the physical space required for high-current power components, cooling equipment, DC-bus connections and associated electrical hardware.

This makes the drive particularly suitable for:

• Large process plants
• Water and wastewater facilities
• Mining installations
• Cement plants
• Steel and metal-processing facilities
• Large HVAC systems
• Oil and gas process equipment
• Material-handling systems
• Large manufacturing lines
• Industrial pumping stations

---

8. Embedded EtherNet/IP

One of the most useful characteristics of this model is its embedded EtherNet/IP capability.

This allows the drive to participate directly in an industrial Ethernet control architecture.

Instead of relying entirely on hardwired start/stop and speed-reference signals, the drive can exchange information with higher-level control equipment.

Typical information can include:

• Start and stop commands
• Speed reference
• Actual speed
• Output current
• Motor status
• Drive status
• Fault information
• Alarm information
• Diagnostic information
• Process-related data

This is especially useful in large plants where many drives are connected to a central automation system.

---

9. DC Terminals

The catalog configuration includes DC terminals.

This is an important difference between this type of drive and simpler AC-input configurations.

The DC-bus architecture can be useful in systems where DC-bus energy management, common-bus arrangements or specialized industrial power configurations are required.

For a large installation, DC-bus design needs careful engineering because the available DC voltage and stored energy can be substantial.

Proper isolation, discharge time, protective equipment and maintenance procedures are therefore essential.

---

10. EMC Filter Configuration

The 20G11BC1K0AN0NNNNN includes an EMC filter.

EMC filtering helps control conducted electromagnetic interference generated by high-frequency power electronics.

This is important in large industrial systems because a high-power variable frequency drive can interact with other electrical and electronic equipment if the installation is not properly designed.

Correct grounding, cable routing, shielding, cabinet construction and motor-cable installation remain important even when the drive includes filtering.

---

11. CM Jumper Removed

The catalog configuration specifies that the CM jumper is removed.

This is an electrical configuration detail that can affect the way the drive’s common-mode filtering and grounding arrangement interacts with the plant electrical system.

The correct configuration depends on the grounding system and application.

This means that the catalog number should not be replaced by a visually similar drive without checking the complete electrical configuration.

For replacement work, the exact catalog number and installation arrangement should be compared.

---

12. Dynamic Braking

The model has no internal dynamic-braking transistor.

This is an important consideration for high-inertia applications.

When a large motor decelerates, mechanical energy can be converted back into electrical energy. That energy can increase the DC-bus voltage.

If rapid deceleration is required, the application may require a separate regenerative or braking solution.

This should be evaluated carefully for:

• Large conveyors
• Centrifuges
• High-inertia fans
• Large rotating equipment
• Certain lifting systems
• Rapid-cycle machinery
• Machines with frequent acceleration and deceleration

For applications with slow deceleration and relatively low regeneration, the lack of an internal braking transistor may not create a problem.

---

13. Cooling System

The drive uses air cooling / forced-air cooling.

At a 1,040 A current rating and hundreds of kilowatts of motor power, heat management becomes a major engineering consideration.

The installation must provide sufficient airflow and appropriate heat removal.

The cooling system should be designed around:

• Drive losses
• Ambient temperature
• Cabinet construction
• Airflow direction
• Filter condition
• Other heat-producing components
• Plant ventilation
• Altitude
• Continuous operating load

A blocked or contaminated cooling path can cause unnecessary thermal stress and may reduce equipment reliability.

---

14. Enclosure and Installation

The specified configuration is a Type 1, IP20, 600 mm deep MCC-style arrangement.

This means that the drive is intended for installation as part of an electrical control/MCC system rather than for direct outdoor exposure.

The cabinet arrangement provides a more substantial level of mechanical integration than a small open-frame drive.

The surrounding electrical room should nevertheless be designed to protect the equipment from:

• Water
• Excessive humidity
• Conductive dust
• Corrosive gases
• Oil contamination
• Excessive vibration
• Foreign objects
• Excessive ambient temperature

---

15. Dimensions and Weight

Because this model is a Frame 9 MCC-style drive, its mechanical dimensions and weight are very different from those of smaller PowerFlex models.

Mechanical Parameter	Specification
Frame	Frame 9
Cabinet style	MCC style
Nominal depth	600 mm
Approximate cabinet height	1200 mm class
Approximate cabinet width	800 mm class
Dimensions	Approximately 1200 × 800 × 600 mm class
Weight (kg)	Approximately 1,246 kg
Cooling	Forced air
Enclosure	Type 1
Protection	IP20
Installation	MCC / electrical cabinet

The published Frame 9 MCC-style information gives approximately 1,246 kg for a 600 mm-depth Frame 9 configuration. The actual complete system weight can vary substantially according to the selected wiring bays, power options, disconnects, reactors, contactors and other accessories.

For transportation and installation, the total assembled cabinet weight should therefore be confirmed from the exact configured equipment rather than relying only on the basic drive rating.

---

16. Product Introduction

The 20G11BC1K0AN0NNNNN is designed for situations where a conventional fixed-speed motor starter is no longer sufficient.

Large motors often need to operate at different speeds depending on production demand.

A variable frequency drive provides that flexibility.

For a pump, the drive can increase or decrease motor speed according to pressure or flow demand.

For a fan, the drive can adjust airflow according to ventilation requirements.

For a conveyor, the drive can control acceleration, running speed and deceleration.

For process machinery, the drive can coordinate motor speed with other production parameters.

At this power level, the ability to control a 500–600 kW-class motor provides significant benefits for large industrial processes.

---

17. Main Product Advantages

17.1 Extremely High Power Capacity

The biggest advantage of the 20G11BC1K0AN0NNNNN is its high power rating.

With 560 kW Normal Duty and 500 kW Heavy Duty, it can control motors far beyond the range of conventional compact drives.

This makes it appropriate for large industrial machinery.

---

17.2 Very High Current Capability

The 1,040 A output rating provides sufficient current capacity for large industrial motors.

This is particularly important where motor current is the limiting factor in drive selection.

For a replacement project, the actual motor nameplate current should always be compared with the drive rating.

---

17.3 Advanced Network Integration

Embedded EtherNet/IP allows the drive to become part of a larger automation network.

This can reduce the number of hardwired control signals and provide more detailed operating information to the supervisory control system.

---

• Manufacturing equipment

The platform also supports advanced control and motion-related functionality in appropriate configurations.

---

17.5 Flexible Motor Control

The PowerFlex 755 platform supports multiple motor-control strategies, including V/Hz and vector-based control approaches.

This provides flexibility when dealing with different motor and load characteristics.

For large industrial machinery, this can be particularly valuable when the machine requires stable torque, accurate speed control or improved dynamic response.

---

17.6 Integrated Diagnostics

Large industrial equipment benefits from detailed drive diagnostics.

Drive status and fault information can be made available to the automation system, helping operators and maintenance personnel identify problems more efficiently.

This can be particularly valuable when the drive is located in a large electrical room or MCC lineup away from the operator station.

---

---

18.2 Large Fans and Blowers

Large industrial fans can require hundreds of kilowatts.

The drive allows airflow to be adjusted by changing motor speed.

Typical applications include:

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

---

18.3 Large Conveyors

Conveyors with very large loads can benefit from controlled motor acceleration.

The drive can gradually increase motor speed instead of applying the full electrical and mechanical load immediately.

This can reduce mechanical shock on:

• Gearboxes
• Conveyor belts
• Couplings
• Bearings
• Drive shafts

---

18.4 Mining Equipment

Large mining equipment often requires very high motor power.

Potential applications include:

• Belt conveyors
• Crushers
• Fans
• Pumps
• Material-handling equipment

Mining applications also require careful consideration of environmental protection, braking, torque requirements and safety systems.

---

20. Five Recommended Models from the Same Series

The following models are useful alternatives or comparison points within the PowerFlex 755 family.

Model	Series	Voltage	Current / Power	Frame	Main Difference	Dimensions / Weight
20G11BC1K1AN0NNNNN	PowerFlex 755	400 VAC	1,090 A; approx. 710 kW LD / 630 kW ND / 500 kW HD	Frame 9	Higher current/power class	Frame 9 MCC style; approx. 1200 × 800 × 600 mm class; approx. 1,246 kg base cabinet class
20G11BC1K2AN0NNNNN	PowerFlex 755	400 VAC	1,175 A; approx. 800 kW LD / 710 kW ND / 560 kW HD	Frame 9	Higher-capacity version	Frame 9; configuration-dependent
20G11BC1K5AN0NNNNN	PowerFlex 755	400 VAC	Higher-current Frame 9 class	Frame 9	Larger motor applications	Frame 9; configuration-dependent
20G11BC910JN0NNNNN	PowerFlex 755	400 VAC	910 A; approx. 560 kW LD / 500 kW ND / 400 kW HD	Frame 9	Lower-current alternative	Frame 9 MCC style; configuration-dependent
20G11BC1K0JN0NNNNN	PowerFlex 755	400 VAC	1,040 A; 630 kW LD / 560 kW ND / 500 kW HD	Frame 9	Closest configuration alternative	600 mm MCC style; approximately 1,246 kg cabinet class

The first three models are useful when the motor or machine requires more current capacity.

The 910 A version is useful when the motor requirement is somewhat lower.

The 20G11BC1K0JN0NNNNN is especially relevant as a configuration alternative because it retains the same major 1,040 A / 560 kW Normal Duty rating while changing the specified configuration of the catalog number.

---

21. Five Popular Models from the Same Brand

For applications outside the exact PowerFlex 755 configuration, the following models provide useful comparisons across the broader product range.

Model	Series	Typical Rating / Configuration	Voltage	Application	Dimensions / Weight
20F1ANF263JN0NNNNN	PowerFlex 753	263 A; 250 kW ND / 200 kW HD	690 VAC	Large industrial motor control	Frame 7; approx. 881.5 × 430 × 349.6 mm; approx. 48 kg
20G11BC910JN0NNNNN	PowerFlex 755	910 A; 500 kW ND / 400 kW HD	400 VAC	Large industrial motor control	Frame 9 MCC style; configuration-dependent
20G11BF590JN0NNNNN	PowerFlex 755	590 A; approx. 560 kW LD / 450 kW HD	690 VAC	High-voltage large motor control	Frame 9; configuration-dependent
25B-D030N114	PowerFlex 525	Approx. 30 A class	480 VAC class	Compact industrial machinery	Compact frame; configuration-dependent
25B-D017N104	PowerFlex 525	Approx. 17 A class	480 VAC class	General machine applications	Compact frame; configuration-dependent

The first three are more relevant when dealing with large industrial motors.

The PowerFlex 525 models are much smaller and are intended for lower-power machinery rather than 500–600 kW motor applications.

The broader PowerFlex range covers substantially different power levels and physical formats, so the motor’s actual current and duty requirements should be used when selecting among them.

---

22. PowerFlex 753 and PowerFlex 755 Comparison

Feature	PowerFlex 753	PowerFlex 755
General positioning	Industrial AC drive	Advanced industrial AC drive
Main application	General industrial motor control	Advanced machine and process control
High-power models	Yes	Yes
Embedded I/O	Yes	Yes
EtherNet/IP	Available	Embedded / highly integrated
Advanced control	Good	Excellent
Motion functionality	More limited	More extensive
System integration	Very good	Excellent
Large motor applications	Yes	Yes
High-power Frame 9 options	Limited	Strong
Best suited for	Pumps, fans, conveyors and general industrial equipment	Large, complex and highly integrated industrial systems

The PowerFlex 755 is generally the more suitable choice when a project requires advanced communications, higher-level control integration or more sophisticated motor-control functionality.

---

23. Communication and Automation Advantages

For large plants, the embedded EtherNet/IP capability is more than a convenience.

It allows the drive to become part of the plant’s automation structure.

An operator can potentially monitor:

• Motor speed
• Motor current
• Drive frequency
• Drive status
• Alarm status
• Fault codes
• Output power
• Operating condition

The control system can also send commands to the drive.

This makes it easier to coordinate large motor-driven equipment with the rest of the production system.

---

24. Maintenance Advantages

Large drives are expensive and important pieces of plant equipment.

The ability to monitor operating status and diagnostic information can help maintenance personnel identify problems before they become major failures.

Potential maintenance benefits include:

• Faster fault identification
• Easier troubleshooting
• Better visibility of drive status
• Reduced diagnostic time
• Easier integration with plant monitoring
• More structured maintenance procedures

For large installations, these benefits can be more significant than the initial convenience of the drive itself.

---

25. Energy Management

A variable frequency drive can provide energy-management benefits, especially in variable-torque applications.

Pumps and fans are good examples.

If process demand falls, the motor can operate at a lower speed instead of continuing to run at full speed.

This can reduce unnecessary mechanical output and may reduce electrical consumption.

The actual energy savings depend on:

• Load profile
• Motor efficiency
• Pump/fan characteristics
• Operating hours
• Process requirements
• Drive efficiency
• Control strategy

Therefore, energy savings should be calculated from the actual machine rather than assumed solely from the presence of a VFD.

---

26. Motor Selection Considerations

Before selecting this drive for a motor, the following parameters should be checked.

Motor Parameter	Importance
Motor voltage	Must match the drive system
Rated current	Primary drive-sizing parameter
Motor power	Must fit the selected duty rating
Motor frequency	Must be compatible with the application
Rated speed	Determines speed-control requirements
Starting torque	Important for conveyors and heavy machinery
Overload requirement	Determines ND/HD suitability
Regenerative load	Important for braking design
Cable length	May affect output filtering and EMC
Motor insulation	Important for high-performance VFD operation
Environmental conditions	Must match the motor and drive installation
Duty cycle	Determines the appropriate drive rating

The 1,040 A rating is very high, so the motor should normally be a large industrial machine.

---

27. Normal Duty, Heavy Duty and Low Duty

The three power classifications are important when selecting the drive.

Duty	Power Rating	Typical Application
Low Duty	630 kW	Less demanding load profile
Normal Duty	560 kW	Pumps, fans and stable industrial loads
Heavy Duty	500 kW	Higher torque and overload requirements

A common mistake is to select the drive solely according to the motor’s nameplate kW.

The machine’s torque curve and overload requirement are equally important.

For example, a 500 kW motor used in a heavy conveyor application may require the Heavy Duty rating even though the drive has a larger Low Duty rating.

---

28. Mechanical Installation

The physical size of this equipment should be considered at the earliest stage of cabinet design.

A Frame 9 MCC-style drive is not a component that can simply be mounted into a small standard control cabinet.

The installation may require:

• MCC lineup space
• Dedicated ventilation
• Large power cable compartments
• Busbar connections
• Lifting equipment
• Service access
• Separate control wiring sections
• Adequate grounding
• Heat management

The approximate 1,246 kg cabinet-level weight also means that transportation and positioning need to be planned before delivery.

---

29. Cabinet and Ventilation Requirements

A high-power air-cooled drive generates considerable heat.

The cabinet must therefore provide a suitable airflow path.

The design should take into account:

1. Air inlet temperature.
2. Air outlet temperature.
3. Fan airflow.
4. Cabinet heat losses.
5. Other equipment installed nearby.
6. Filter maintenance.
7. Ambient temperature.
8. Installation altitude.

A drive can have excellent electrical specifications but still experience reliability problems if the cabinet ventilation is inadequate.

---

30. Braking and Regeneration Considerations

Because this catalog number does not contain an internal dynamic-braking transistor, applications involving rapid deceleration need special attention.

A high-inertia 560 kW-class machine can return a significant amount of energy to the drive during deceleration.

Depending on the application, the system may need:

• External braking equipment
• Regenerative equipment
• Longer deceleration time
• Mechanical braking
• A coordinated energy-management arrangement

For a pump or fan with a long natural coast-down period, this may not be a significant issue.

For a high-speed conveyor or high-inertia machine requiring frequent stopping, it can become a major design consideration.

---

31. Application Advantages

Application	Main Benefit
Large pump	Adjustable flow and pressure
Large fan	Adjustable airflow
Conveyor	Smooth acceleration and speed control
Compressor	Adjustable operating speed
Crusher	Controlled motor operation
Mining equipment	High current and power capacity
Process equipment	Networked control and diagnostics
Cooling system	Variable-speed operation
Material handling	Centralized speed control
Industrial ventilation	Process-based airflow regulation

---

32. Key Strengths of the 20G11BC1K0AN0NNNNN

Strength	Practical Meaning
1,040 A output	Suitable for very large motors
560 kW ND	High continuous motor-control capacity
500 kW HD	Suitable for demanding loads
630 kW LD	High capacity for less demanding duty
400 VAC	Compatible with common industrial voltage systems
Frame 9	High-power industrial architecture
Embedded EtherNet/IP	Direct automation-network integration
DC terminals	Suitable for advanced DC-bus arrangements
EMC filter	Improved electromagnetic compatibility
Air cooling	Practical high-power thermal-management method
MCC-style design	Suitable for large electrical installations
No HIM	Flexible operator-interface configuration
No DB transistor	Suitable when internal dynamic braking is unnecessary

---

33. Recommended Selection Strategy

When evaluating this model for a project, the following sequence is recommended.

Step 1 — Confirm the Motor Voltage

Check the motor nameplate.

The motor and drive electrical system must be compatible with the 400 VAC configuration.

Step 2 — Confirm Motor Current

Check the motor’s rated full-load current.

The drive should be selected based on current and duty requirements, not simply horsepower.

Step 3 — Identify the Load Type

Determine whether the machine is:

• Variable torque
• Constant torque
• High overload
• High inertia
• Regenerative

Step 4 — Determine Duty

Select Low Duty, Normal Duty or Heavy Duty according to the actual application.

Step 5 — Check Braking

Determine whether the motor must stop quickly.

If yes, evaluate regeneration and braking requirements.

Step 6 — Check Communication

Determine whether embedded EtherNet/IP is appropriate for the control architecture.

Step 7 — Check Cabinet Space

Allow space for the Frame 9 MCC-style equipment, cables, cooling and service access.

Step 8 — Check Weight

A cabinet-level weight of approximately 1,246 kg means that transportation, floor loading and lifting requirements must be considered.

---

34. Product Positioning

The 20G11BC1K0AN0NNNNN occupies the high-power end of the PowerFlex 755 range.

It is not intended for small motors or simple standalone machine applications.

Its strengths become apparent when the application has:

• Very high motor power
• Large current requirements
• Centralized plant control
• Network communication
• Complex process requirements
• Large electrical infrastructure
• High-value rotating equipment

For a small production machine, a compact drive would generally be a more practical solution.

For a 500–600 kW industrial motor, however, a Frame 9 architecture is much more appropriate.

---

35. Final Product Summary

The 20G11BC1K0AN0NNNNN is a high-power PowerFlex 755 AC drive with a 1,040 A output rating and a 400 VAC three-phase input configuration.

The model is particularly well suited to large pumps, large fans, conveyors, mining equipment, compressors, process machinery, cooling systems and other heavy industrial applications.

Its biggest advantages are the combination of 1,040 A current capacity, 560 kW Normal Duty rating, 500 kW Heavy Duty rating, 400 VAC three-phase operation, Frame 9 construction and embedded EtherNet/IP.

The large physical size and approximately 1,246 kg cabinet-level weight mean that installation planning is just as important as electrical selection.

For replacement work, the exact catalog number should be checked carefully because configuration details such as CM jumper position, dynamic-braking capability, HIM configuration, filtering, cabinet depth and power options can change the behavior and installation requirements.

A particularly important point is that 20G11BC1K0AN0NNNNN is a discontinued catalog configuration, so it should be treated primarily as an existing-equipment or replacement-reference model rather than automatically assumed to be a current standard-production selection. A direct replacement configuration has been identified for this catalog number.

Overall, the 20G11BC1K0AN0NNNNN can be regarded as a large-frame, high-current, high-power industrial AC drive intended for demanding motor-control applications where several hundred kilowatts of motor power and advanced plant-level integration are required.
