20G11BF1K4JN0NNNNN PowerFlex 755 AC Drive — Detailed Product Information, Technical Parameters, Applications, Advantages and Model Recommendations

1. Product Overview

The 20G11BF1K4JN0NNNNN is a high-power AC variable frequency drive belonging to the PowerFlex 755 series. It is designed for large industrial motors and demanding process-control applications where high output power, high current capacity, reliable speed regulation and integration with an industrial automation system are required.

This model is a particularly large configuration within the PowerFlex 755 family. It uses a 690 VAC three-phase input, has a rated current of approximately 1,400 A, and provides power ratings of approximately 1,500 kW for Light Duty, 1,400 kW for Normal Duty and 1,120 kW for Heavy Duty.

The drive uses a Frame 10 power section and a large 600 mm deep MCC-style enclosure. It is forced-air cooled and uses an IP20 / Type 1 enclosure arrangement intended for installation inside a suitable industrial electrical environment.

The model also incorporates EtherNet/IP communication, which allows the drive to be connected to an industrial control network. This is especially useful where the motor drive needs to exchange speed references, operating commands, status information, fault information and diagnostic data with a PLC or other automation controller.

The J configuration in the catalog number is important because it identifies the factory filtering and common-mode configuration. Compared with the older 20G11BF1K4AN0NNNNN configuration, the 20G11BF1K4JN0NNNNN is the current replacement-oriented configuration and uses the corresponding factory-installed filtering / common-mode jumper arrangement.

The original configuration represented by the older A-coded version has been replaced by the J-coded configuration. Therefore, for a new project or replacement project, 20G11BF1K4JN0NNNNN is the more appropriate configuration to evaluate.

4. Product Model Number Explanation

The catalog number 20G11BF1K4JN0NNNNN contains a series of configuration characters that identify the electrical and mechanical characteristics of the drive.

The 20G portion identifies the PowerFlex 755 drive family.

The following configuration characters define the particular construction and electrical arrangement.

The B configuration identifies the IP20 / Type 1, 600 mm deep MCC-style enclosure arrangement.

The F configuration identifies the applicable 690 VAC voltage class.

The 1K4 designation corresponds to the approximately 1,400 A current class.

The J configuration indicates the specified factory filtering and common-mode jumper arrangement.

The N dynamic-braking configuration indicates that an internal dynamic braking transistor is not included in this particular configuration.

The final N-coded positions represent configurations where no additional option is selected in those catalog positions.

For engineering purposes, the entire catalog number should always be treated as one complete configuration. It is not recommended to assume that two models are interchangeable simply because most of their characters are similar.

---

5. Product Introduction

The PowerFlex 755 series is designed for applications that require more sophisticated motor control than a basic general-purpose inverter.

The 20G11BF1K4JN0NNNNN is positioned toward the upper end of this product family and is intended for extremely large industrial motor systems.

A drive of this size is normally installed as part of a larger electrical system. The incoming 690 VAC supply is connected to the drive, while the controlled output is connected to a large AC motor.

The drive controls the electrical frequency and voltage supplied to the motor, allowing the motor’s operating speed and torque to be adjusted according to the requirements of the process.

This type of control is particularly useful when the driven equipment does not need to operate continuously at full speed.

For example, a large pump may require a different speed during normal operation compared with startup or low-demand conditions. Similarly, a conveyor may need to operate at different speeds depending on production throughput.

By allowing the motor to operate at a controlled speed, the drive can improve process flexibility and reduce unnecessary mechanical operation.

---

6. Electrical Performance

The most important electrical characteristic of the 20G11BF1K4JN0NNNNN is its 1,400 A current rating.

This is a very high current capacity and places the product firmly in the high-power industrial-drive category.

At the 690 VAC level, the drive is suitable for large motor systems where the electrical distribution system is designed around high-voltage, high-power three-phase equipment.

The drive provides different power ratings according to the required duty level.

Duty Classification	Approximate Power Rating	Typical Requirement
Light Duty	1,500 kW	Applications with relatively moderate overload requirements
Normal Duty	1,400 kW	Standard industrial variable-speed applications
Heavy Duty	1,120 kW	Applications requiring greater overload capability
Rated Current	1,400 A	Main drive current class

The distinction between Light Duty, Normal Duty and Heavy Duty is important.

A machine should not be selected purely by comparing the motor’s nominal kilowatts with the drive’s maximum advertised power.

The motor current, overload profile, acceleration requirements, load inertia and operating cycle must also be considered.

---

7. Dimensions and Weight

Because this is a very large Frame 10 drive, physical installation requirements are significant.

The commonly specified mechanical envelope for this configuration is approximately 2,453 mm high × 1,200 mm wide × 600 mm deep.

The approximate equipment weight is 1,905 kg.

For practical engineering work, these values should be considered installation-planning values rather than a substitute for the final mechanical drawing.

Mechanical Parameter	Specification
Frame	Frame 10
Height	Approx. 2,453 mm
Width	Approx. 1,200 mm
Depth	Approx. 600 mm
Cabinet Style	MCC Style
Protection	IP20 / Type 1
Approx. Weight (kg)	1,905 kg
Cooling	Forced Air
Installation	Cabinet / MCC
Service Space	Additional clearance required around the equipment
Transportation	Heavy industrial equipment handling required

The approximate 1,905 kg weight is particularly important for transportation and installation planning.

A unit of this size may require suitable lifting equipment, reinforced floor arrangements, appropriate cabinet access and sufficient service clearance.

The dimensions should also be considered together with cable bending radius, incoming power connections, outgoing motor cables, ventilation and maintenance access.

---

8. Product Applications

8.1 Large Pumping Systems

Large industrial pumps are one of the most suitable applications for a high-power variable frequency drive.

The drive can adjust motor speed according to required flow and pressure.

This can be useful in industrial water systems, cooling-water circulation, process-fluid systems, large pumping stations and other continuous-process applications.

The ability to control acceleration is also valuable because large pumps can contain substantial rotating inertia.

---

8.2 Large Fans and Blowers

Large fans and blowers often operate under changing process requirements.

Instead of running continuously at maximum speed, the motor can be controlled according to the required airflow.

This type of application is common in large ventilation systems, industrial exhaust systems, combustion-air systems and cooling installations.

---

8.3 Mining Conveyors

Large mining conveyors can require very high motor power.

The 1,400 A current capability makes this drive suitable for very large conveyor systems where motor starting and speed control are important.

Controlled acceleration can reduce sudden mechanical stress on conveyor belts, couplings, gearboxes and other drive-train components.

---

8.4 Cement Production

Cement and mineral-processing equipment frequently includes large motors.

Potential applications include:

• Large fans
• Mills
• Conveyors
• Crushers
• Material-handling systems
• Process pumps
• Dust-handling systems

The high power rating of the drive makes it suitable for the large motor systems used in these processes.

---

8.5 Steel and Metals Processing

Large steel and metal-processing facilities often use high-power motors for rollers, pumps, fans, material handling and process machinery.

Variable-speed control can be used to coordinate motor operation with the production process.

---

8.6 Material Handling

Large material-handling systems can benefit from controlled acceleration and deceleration.

The drive can be integrated into a plant-level automation system so that motor speed follows the requirements of the production line.

---

8.7 Large Compressor Systems

Some large compressor applications can use variable-speed drives to control motor operation.

However, compressor type, starting torque, speed range, acceleration profile and process control requirements should be checked carefully before selecting the drive.

---

9. Product Advantages

9.1 Very High Power Capacity

The most obvious advantage is the extremely high power capacity.

With approximately 1,400 A of rated current and up to approximately 1,500 kW Light Duty, the drive can serve large motors that are far beyond the practical range of compact industrial drives.

---

9.2 690 VAC Voltage Class

The 690 VAC class is well suited to large industrial motor systems.

At high power levels, operating at a higher voltage can reduce the current required for a given power level compared with lower-voltage systems.

This can be beneficial when designing large motor feeders and industrial power-distribution systems.

---

9.3 Embedded EtherNet/IP

The embedded EtherNet/IP capability is an important advantage for integrated automation systems.

The drive can exchange information with the control system, allowing operators and controllers to monitor operating conditions and manage the motor from a centralized automation architecture.

---

9.4 Controlled Acceleration

Large motors and large mechanical loads can experience substantial stress during starting.

Variable-frequency control allows acceleration to be managed progressively.

This can reduce mechanical shock and make startup behavior easier to coordinate with the production process.

---

9.5 Flexible Speed Control

The motor does not have to operate at a fixed speed.

The drive can provide a variable operating speed according to the process requirement.

This is particularly useful for pumps, fans, conveyors and other variable-load equipment.

---

9.6 Industrial-Scale Construction

The Frame 10 MCC-style construction is intended for large industrial electrical installations.

This makes the product more appropriate for centralized motor-control rooms, large electrical rooms and industrial MCC environments than compact machine-mounted drives.

---

9.7 Integrated Diagnostics

A network-connected drive can provide useful operating and diagnostic information to the control system.

This can simplify troubleshooting and help maintenance personnel identify abnormal operating conditions.

---

10. Product Limitations and Engineering Considerations

The large size of the drive is both an advantage and a limitation.

For a small or medium-size motor, this model would be substantially oversized.

The drive is intended for applications where the motor power and current requirements justify a large Frame 10 installation.

The IP20 / Type 1 construction also means that the drive should be installed in an appropriate protected electrical environment.

It should not be treated as an outdoor weatherproof enclosure without additional protection.

Cooling is another important consideration.

A drive with this electrical capacity generates significant heat, so ventilation, airflow, room temperature and heat dissipation must be considered during system design.

The drive also has no internal dynamic braking configuration in the specified catalog number.

If the application involves rapid deceleration or a high-inertia load that regenerates substantial energy into the DC bus, the braking requirements must be evaluated separately.

---

11. Five Recommended Models from the Same Series or Closely Related Configurations

The following models are useful comparison candidates when evaluating the 20G11BF1K4JN0NNNNN.

Model	Series	Voltage	Current	LD Rating	ND Rating	HD Rating	Dimensions / Depth	Weight (kg)
20G11BF1K4JN0NNNNN	PowerFlex 755	690 VAC	1,400 A	1,500 kW	1,400 kW	1,120 kW	Approx. 2453 × 1200 × 600 mm	Approx. 1,905
20G11BF1K4JN4NNNNN	PowerFlex 755	690 VAC	1,400 A	1,500 kW class	1,400 kW	1,120 kW	Approx. 2453 × 1200 × 800 mm	Approx. 1,905+
20G11JF1K4JN0NNNNN	PowerFlex 755	690 VAC	1,400 A	1,500 kW class	1,400 kW	1,120 kW	Approx. 2453 × 1200 × 800 mm class	Approx. 1,900+
20G11BE1K4JN0NNNNN	PowerFlex 755	600 VAC	1,430 A	1,500 hp class	1,400 hp	1,250 hp	Approx. 2453 × 1200 × 600 mm class	Approx. 1,900
20G11BC1K4JN0NNNNN	PowerFlex 755	400 VAC	1,465 A	850 kW	800 kW	630 kW	Approx. 2453 × 1200 × 600 mm class	Approx. 1,800–1,900

The models above should be viewed as engineering comparison candidates rather than automatically interchangeable products.

The 20G11BF1K4JN4NNNNN is particularly relevant when a different cabinet depth or configuration is required.

The 20G11JF1K4JN0NNNNN is also closely related electrically but uses the deeper MCC-style construction.

The 20G11BE1K4JN0NNNNN is useful when the plant uses a 600 VAC-class electrical system.

The 20G11BC1K4JN0NNNNN is useful for a lower-voltage, high-current application where the motor power requirement is lower than the 690 VAC 1,400 A configuration.

Because the exact shipping weight can change with cabinet construction and installed components, weights for the related models should be confirmed before transportation, lifting or foundation calculations.

12. Five Popular Models from the Same Brand

For users who want alternatives within the same brand but not necessarily the same PowerFlex 755 configuration, the following models are useful reference products.

Model	Product Family	Typical Voltage Class	Current / Power Class	Main Application	Construction	Dimensions	Weight (kg)
20G11BF1K4JN0NNNNN	PowerFlex 755	690 VAC	1,400 A / 1,400 kW ND	Large industrial machinery	Frame 10 MCC	Approx. 2453 × 1200 × 600 mm	Approx. 1,905
20G11JF1K0JN0NNNNN	PowerFlex 755	690 VAC	1,040 A / 1,000 kW ND	Large pumps, fans and process equipment	Frame 10 MCC	Approx. 2453 × 1200 × 800 mm class	Approx. 1,800+
20G11BE1K4JN4NNNNN	PowerFlex 755	600 VAC	1,430 A / 1,400 hp ND	Large industrial motor systems	Frame 10 MCC	Approx. 2453 × 1200 × 600–800 mm class	Approx. 1,900+
25B-D017N104	PowerFlex 525	480 VAC class	Small-to-medium power	General machinery, pumps and fans	Compact drive	Compact, model dependent	Model dependent
25B-D024N114	PowerFlex 525	480 VAC class	Small-to-medium power	Machine automation and general motor control	Compact drive	Compact, model dependent	Model dependent

The last two models belong to a much smaller drive class and should not be considered direct replacements for the 1,400 A PowerFlex 755.

They are included because they are representative of popular smaller drive configurations when the motor power requirement is significantly lower.

---

13. Same-Series Model Comparison

Model	Main Voltage	Current	ND Power	HD Power	Depth	Major Characteristic
20G11BF1K4JN0NNNNN	690 VAC	1,400 A	1,400 kW	1,120 kW	600 mm	Main reference model
20G11BF1K4JN4NNNNN	690 VAC	1,400 A	1,400 kW	1,120 kW	800 mm class	Alternative cabinet configuration
20G11JF1K4JN0NNNNN	690 VAC	1,400 A	1,400 kW	1,120 kW	800 mm	Deeper MCC configuration
20G11BE1K4JN0NNNNN	600 VAC	1,430 A	1,400 hp	1,250 hp	600 mm	600 VAC version
20G11BC1K4JN0NNNNN	400 VAC	1,465 A	800 kW	630 kW	600 mm	400 VAC high-current version

The most important difference between these models is not simply the current rating.

Voltage class, cabinet depth, filtering, enclosure configuration, braking configuration and motor-duty requirements can all affect whether a particular model is suitable.

---

14. Selection Comparison by Application

Application	Recommended Direction	Reason
1.4 MW, 690 VAC large motor	20G11BF1K4JN0NNNNN	Closely matches the electrical requirement
Existing 20G11BF1K4AN0NNNNN replacement	20G11BF1K4JN0NNNNN	Closely aligned replacement configuration
690 VAC system requiring deeper cabinet	20G11JF1K4JN0NNNNN	800 mm-class MCC configuration
600 VAC large motor	20G11BE1K4JN0NNNNN	Appropriate voltage class
400 VAC high-power motor	20G11BC1K4JN0NNNNN	400 VAC high-current configuration
Medium-size industrial motor	PowerFlex 753 family	More suitable power range
Small or medium machine	PowerFlex 525 family	Compact and economical architecture

---

15. Why the 20G11BF1K4JN0NNNNN Is a Strong Replacement Candidate

For an existing installation that previously used 20G11BF1K4AN0NNNNN, the 20G11BF1K4JN0NNNNN is particularly important because it maintains the same general high-power electrical and mechanical concept.

The major characteristics remain centered around:

• 690 VAC
• 1,400 A
• Frame 10
• 600 mm MCC-style construction
• IP20 / Type 1
• Forced-air cooling
• AC input with precharge and DC terminals
• 1,400 kW Normal Duty
• 1,120 kW Heavy Duty
• Embedded EtherNet/IP
• Filtered configuration
• CM jumper installed
• No internal dynamic braking configuration

This makes it much more logical as a replacement candidate than selecting a smaller drive simply because its horsepower appears similar.

---

16. Installation Considerations

The physical dimensions of approximately 2.453 m high × 1.2 m wide × 0.6 m deep mean that installation planning should begin before the drive is ordered.

The electrical room must have sufficient floor space.

The installation must also provide enough room for power cables and control wiring.

Ventilation is important because this is a forced-air-cooled high-power drive.

The cooling-air path should not be blocked by nearby equipment.

The room’s ambient temperature must also remain within the allowable operating range of the drive system.

Because the approximate weight is 1,905 kg, transportation and lifting should be treated as a major installation activity rather than ordinary electrical-equipment handling.

A suitable lifting method, floor loading calculation and access route should be planned in advance.

---

17. Maintenance Considerations

For a drive of this size, preventive maintenance is important.

Cooling fans should be inspected because the cooling system is critical to the drive’s thermal performance.

Electrical connections should be inspected according to the applicable maintenance procedure.

The cabinet should be kept free from excessive dust and contamination.

Network communication should also be checked when the drive forms part of an automated production system.

Fault history and diagnostic information can be useful when investigating intermittent problems.

The actual maintenance interval should be determined according to operating environment, load profile, temperature, dust level and plant maintenance standards.

---

18. Advantages for Automation Systems

One of the strongest characteristics of this drive is its suitability for integrated automation.

The embedded EtherNet/IP interface means that the drive can be connected to a compatible industrial controller without necessarily requiring a separate communication module for basic network integration.

Typical control data can include:

Control / Monitoring Item	Typical Use
Start Command	Start motor operation
Stop Command	Stop motor operation
Speed Reference	Set desired motor speed
Actual Speed	Monitor motor operating speed
Output Current	Monitor motor loading
Drive Status	Determine operating condition
Warning Status	Identify abnormal conditions
Fault Status	Identify drive faults
Fault Information	Assist troubleshooting
Parameter Data	Configure and monitor drive behavior

This communication capability is especially useful in large process plants where many high-power motors must be coordinated.

---

19. Advantages for Energy Management

Variable-speed operation can provide energy benefits in applications where the load varies with speed.

The greatest potential benefit is usually seen in variable-torque applications such as centrifugal pumps and fans.

If a process does not require full speed continuously, the drive can reduce motor speed rather than forcing the motor to operate at maximum speed all the time.

The actual energy savings depend on the motor, load curve, operating schedule, process requirements and overall system design.

Therefore, the drive itself should not be considered an automatic energy-saving device. The greatest benefit occurs when the process allows motor speed to be reduced.

---

20. Advantages for Mechanical Systems

Controlled acceleration and deceleration can be particularly valuable for large mechanical systems.

A large conveyor, for example, may contain a substantial amount of stored mechanical energy.

Starting such a system abruptly can result in high mechanical stress.

Variable-speed control can provide a smoother transition from zero speed to operating speed.

This can help reduce stress on:

• Gearboxes
• Couplings
• Conveyor belts
• Shafts
• Bearings
• Pumps
• Fans
• Mechanical brakes
• Production equipment

The exact mechanical benefit depends on the machine design and control strategy.

---

21. Important Difference Between Normal Duty and Heavy Duty

A common mistake when selecting a high-power drive is to focus only on the Normal Duty power rating.

The 20G11BF1K4JN0NNNNN has an approximately 1,400 kW Normal Duty rating and approximately 1,120 kW Heavy Duty rating.

This means that a motor/application requiring heavy-duty overload performance should not simply be selected based on the 1,400 kW figure.

The machine’s operating cycle must be evaluated.

If the motor experiences frequent high torque, acceleration loads, overload conditions or demanding mechanical cycles, the Heavy Duty rating may be the more appropriate basis for selection.

---

25. Conclusion

The 20G11BF1K4JN0NNNNN is a large-frame PowerFlex 755 AC drive designed for demanding industrial motor applications.

Its combination of 690 VAC input, 1,400 A rated current, approximately 1,400 kW Normal Duty capacity, 1,120 kW Heavy Duty capacity, Frame 10 construction and embedded EtherNet/IP makes it suitable for some of the largest conventional low-voltage industrial motor-control applications.

The product is particularly well matched to large pumps, fans, conveyors, mining equipment, cement machinery, material-handling systems, steel-processing equipment and other process machinery requiring controlled speed and high motor power.

Its approximately 2,453 mm × 1,200 mm × 600 mm physical envelope and approximately 1,905 kg weight also show that this is not a compact machine-level inverter. It is a major industrial electrical assembly that requires appropriate transportation, lifting, cabinet access, ventilation and maintenance planning.

For an existing installation based on the older 20G11BF1K4AN0NNNNN, the 20G11BF1K4JN0NNNNN is especially relevant because it represents the replacement-oriented configuration within the same PowerFlex 755 high-power platform.

When selecting this drive for a real project, the most important factors are the motor’s rated voltage, rated current, required duty classification, overload characteristics, acceleration requirements, braking requirements, incoming supply, enclosure requirements, cooling conditions, communication architecture and available installation space.

Overall, the 20G11BF1K4JN0NNNNN can be summarized as a 690 VAC, 1,400 A, Frame 10, megawatt-class industrial AC drive designed for high-power variable-speed motor control and automation-system integration.
