Allen-Bradley 20G14NF212JN0NNNNN PowerFlex 755 AC Drive — Detailed Specifications, Product Introduction, Applications, Advantages and Related Models

1. Product Overview

The Allen-Bradley 20G14NF212JN0NNNNN is a high-power PowerFlex 755 air-cooled AC drive designed for large industrial motor-control applications.

This model is rated for 690 VAC, three-phase operation and provides a 212 A Normal Duty rating corresponding to 200 kW, together with a 171 A Heavy Duty rating corresponding to 160 kW.

The drive uses a DC input with precharge configuration and is built in a Frame 7 open-type enclosure. It is designed for installation inside a suitable industrial electrical cabinet or control enclosure.

The JN0 configuration is important because this version does not include the internal dynamic braking transistor. Unlike the JA0 version of the same 212 A drive, the JN0 version is intended for applications where an internal dynamic braking transistor is not required.

This makes the model a practical choice for high-power applications where the motor and mechanical system do not require the additional dynamic braking hardware provided by the JA0 configuration.

The drive also features a filtered configuration with the CM jumper installed, a blank/no-HIM arrangement, forced-air cooling, and an industrial PowerFlex 755 architecture suitable for integration into larger automation systems.

3. Detailed Electrical Parameters

The 20G14NF212JN0NNNNN is a 690 VAC high-power drive intended for applications where a large motor requires controlled variable-frequency operation.

Its Normal Duty rating is 212 A / 200 kW, while the Heavy Duty rating is 171 A / 160 kW.

These two ratings should not be treated as interchangeable simply because they are listed on the same drive.

Normal Duty is generally associated with applications that have relatively moderate overload requirements and smoother load characteristics.

Heavy Duty is more appropriate when the motor must provide greater overload capability for demanding mechanical loads.

The actual motor full-load current, overload requirement, acceleration profile, and process duty cycle should therefore be considered before selecting the drive.

4. Normal Duty Rating

The 212 A / 200 kW Normal Duty rating is one of the defining characteristics of this model.

This makes the drive suitable for large motors used in industrial processes where the load generally operates within a relatively predictable range.

Typical examples include large pumps, fans, blowers, compressors, process machinery, and other applications where the motor does not continuously experience severe overload conditions.

When selecting the drive, it is important to compare the motor’s actual current rather than relying only on the motor’s kW rating.

A 200 kW motor may have different current requirements depending on motor efficiency, power factor, operating voltage, motor design, and application conditions.

---

5. Heavy Duty Rating

The Heavy Duty rating of the 20G14NF212JN0NNNNN is 171 A / 160 kW.

This rating is useful for applications where the mechanical load requires additional overload capability.

Conveyors, mixers, crushers, high-inertia machinery, material-handling systems, and other mechanically demanding equipment can fall into this category.

The Heavy Duty rating is lower in kW than the Normal Duty rating because the drive is being used under a more demanding thermal and overload profile.

For a real machine, the selection should be based on the required operating current and overload conditions rather than simply choosing the largest kW number shown on the drive label.

Duty Classification	Current Rating	Power Rating	Typical Load Type
Normal Duty	212 A	200 kW	Pumps, fans, blowers, process equipment
Heavy Duty	171 A	160 kW	Conveyors, mixers, high-inertia machinery
Drive Frame	—	Frame 7	High-power industrial installation

---

6. Dynamic Braking Configuration

The JN0 configuration does not include the internal dynamic braking transistor.

This is the most important difference between the JN0 and JA0 versions of the same 212 A drive.

For applications where dynamic braking is not required, the JN0 configuration provides a straightforward high-power drive solution without the additional internal braking transistor.

Dynamic braking is normally used when the motor must decelerate rapidly and the mechanical system produces substantial regenerative energy.

When the motor slows down, stored kinetic energy can be transferred back toward the drive’s DC bus. A properly designed braking system can dissipate this energy through a braking resistor.

Because the 20G14NF212JN0NNNNN does not include the internal DB transistor, it should not be treated as the same braking configuration as the JA0 version.

Braking Parameter	20G14NF212JN0NNNNN
Dynamic Braking	None
Internal DB Transistor	No
Internal Braking Resistor	No
JA0 Comparison	JA0 includes DB transistor
JN0 Configuration	No internal DB transistor
Main Advantage	Simplified configuration where dynamic braking is not required
Typical Application	Loads with normal deceleration requirements

7. JN0 Versus JA0

The difference between these two catalog numbers is important when selecting a replacement or designing a new machine.

Both drives provide the same 212 A / 200 kW Normal Duty rating and 171 A / 160 kW Heavy Duty rating.

Both are 690 VAC, three-phase, Frame 7 PowerFlex 755 drives.

The main difference is the dynamic braking configuration.

The 20G14NF212JA0NNNNN includes an internal dynamic braking transistor.

The 20G14NF212JN0NNNNN does not.

Therefore, if the machine has significant regenerative energy or requires rapid controlled deceleration, the braking configuration must be considered before choosing the JN0 version.

8. Product Introduction

The PowerFlex 755 platform is designed for industrial motor applications that require more capability than a basic compact variable-frequency drive.

The platform is intended for integration into larger automation systems, making it suitable for machinery and process equipment where the drive needs to communicate with the plant control system.

The 20G14NF212JN0NNNNN represents the high-power end of the 690 VAC air-cooled PowerFlex 755 range.

Its 200 kW Normal Duty rating makes it appropriate for large motors and large process equipment.

The Frame 7 mechanical design also reflects its intended application level. This is not a small panel-mounted drive that can simply be installed anywhere inside a compact enclosure. It requires appropriate cabinet space, ventilation, cable routing, grounding, and service access.

---

9. Product Series

The product belongs to the PowerFlex 755 series.

PowerFlex 755 drives are designed for industrial applications where motor control, networking, diagnostics, and system integration are important.

The series includes multiple voltage classes and power ratings, allowing engineers to use a common drive architecture across a range of motor sizes.

This can simplify plant standardization.

For example, a facility may use smaller PowerFlex drives on auxiliary equipment and PowerFlex 755 drives on larger process motors.

The control philosophy and general drive architecture can remain familiar across different applications.

10. Main Applications

10.1 Large Pumps

Large industrial pumps are one of the most natural applications for a drive of this size.

Variable-speed control allows the pump to operate according to actual process demand rather than running continuously at a fixed speed.

The 200 kW Normal Duty rating provides sufficient capacity for many large pumping systems.

Typical applications include industrial water circulation, cooling-water systems, process pumping, water treatment, and large fluid-transfer systems.

---

10.2 Large Fans and Blowers

Large fans and blowers often have variable process requirements.

Using a variable-frequency drive allows motor speed to be adjusted according to airflow requirements.

This can provide better process control than simply operating the motor at full speed and controlling airflow mechanically.

The drive’s high power rating makes it suitable for large industrial ventilation and air-moving equipment.

---

10.3 Compressors

Industrial compressors can require substantial motor power and carefully controlled acceleration.

The 690 VAC rating is useful in facilities where high-voltage motor distribution is already established.

The PowerFlex 755 architecture also makes the drive suitable for integration with process control systems.

---

10.4 Conveyors

Large conveyors can require significant motor power, particularly in mining, bulk material handling, and large production facilities.

Variable-speed control allows the conveyor speed to be matched to production requirements.

The JN0 configuration can be suitable where the application does not require the internal dynamic braking transistor.

If rapid stopping or high regenerative energy is expected, however, the braking requirements should be evaluated before selecting JN0.

---

10.5 Mixers and Agitators

Mixers can have substantial starting torque, particularly when starting with material already inside the vessel.

The Heavy Duty rating is especially important for these applications.

Motor current and starting torque should be checked carefully because the nominal motor kW alone does not fully describe the mechanical load.

---

10.6 Centrifuges

Centrifuges can involve high rotational speed and significant stored kinetic energy.

The acceleration and deceleration requirements should therefore be reviewed carefully.

For centrifuges that require aggressive braking, the absence of an internal DB transistor on the JN0 model needs to be considered during system design.

---

10.7 Process Machinery

The drive is suitable for a wide variety of continuous-process equipment.

Potential applications include:

• Paper processing equipment.
• Metals-processing machinery.
• Large production lines.
• Industrial material handling.
• Process pumps.
• Industrial blowers.
• Large fans.
• Compressors.
• Mixers.
• Machine systems requiring high-power variable-speed control.

---

11. Product Advantages

11.1 200 kW Normal Duty Capacity

The 200 kW Normal Duty rating allows the drive to handle large industrial motors.

This makes it suitable for applications where smaller compact drives are no longer appropriate.

---

11.2 690 VAC Voltage Class

The 690 VAC rating is particularly useful for large industrial motor systems.

At a given power level, higher voltage allows the system to operate at a lower current compared with an equivalent lower-voltage system.

This can have an impact on motor cable sizing, switchgear, busbar design, and electrical distribution.

---

11.3 High-Power Frame 7 Construction

The Frame 7 architecture provides a robust platform for large industrial applications.

It also gives the drive sufficient physical capacity for its high-power electrical design.

The larger physical size should be considered during cabinet design.

---

11.4 Embedded Ethernet/IP

Embedded Ethernet/IP capability is useful when the drive needs to communicate with the machine or plant control system.

The control system can use the drive for functions such as:

• Speed reference.
• Run/stop commands.
• Status monitoring.
• Fault monitoring.
• Warning monitoring.
• Current monitoring.
• Drive diagnostics.
• Process feedback.

This can reduce the need for separate communication hardware for basic network integration.

---

11.5 Filtered Configuration

The drive is supplied in a filtered configuration with the CM jumper installed.

This is useful for industrial installations where electromagnetic compatibility and common-mode considerations are part of the electrical design.

Filtering does not eliminate the need for good installation practices.

Cable routing, grounding, motor-cable construction, cabinet layout, and bonding still matter.

---

11.6 No HIM Configuration

The blank/no-HIM arrangement can be useful in cabinet-based automation systems.

Many modern installations use a remote HMI or PLC-based control architecture rather than requiring a local operator keypad directly on every drive.

This can make the cabinet layout cleaner and can allow operators to control the process from a central interface.

---

12. Advantages of the JN0 Configuration

The JN0 configuration is particularly attractive when the machine does not require internal dynamic braking.

There is little value in selecting a braking-equipped configuration when the mechanical system does not generate significant regenerative energy during normal operation.

For applications with smooth acceleration and deceleration, the JN0 configuration can therefore be a practical choice.

It is also useful when braking is handled by another part of the system architecture or when the application does not require rapid deceleration.

The key point is that JN0 should be selected intentionally.

It is not simply a cheaper or different version of JA0; it represents a different braking configuration.

---

13. Mechanical Specifications

The 20G14NF212JN0NNNNN is a Frame 7 drive.

The approximate physical dimensions are:

430 mm wide × 881.5 mm high × 349.6 mm deep.

The approximate weight is in the range of 72.6–108.9 kg, depending on the final configuration and installed hardware.

These dimensions and weight are important for cabinet engineering.

A cabinet should not be designed around the drive body alone.

Additional room is needed for power connections, motor cables, grounding, control wiring, network cables, airflow, maintenance access, and surrounding equipment.

14. Environmental Specifications

Because this is a high-power forced-air drive, thermal management is an important part of the installation.

The typical operating temperature range is approximately 0 to 50 °C, subject to the specific installation and rating conditions.

Relative humidity is approximately 5–95% non-condensing, while storage temperature is approximately -40 to +70 °C.

The drive should be protected from condensation and unsuitable environmental conditions.

Dust, corrosive gases, excessive humidity, and high cabinet temperatures can all affect long-term reliability.

---

15. Cabinet Installation

A Frame 7, 200 kW-class drive should be treated as a major cabinet component.

The cabinet designer needs to consider both electrical and thermal requirements.

The drive produces heat during operation, and the forced-air cooling system requires adequate airflow.

The cabinet should provide appropriate ventilation while also preventing contaminants from entering the electrical system.

Cable routing is another important consideration.

Large motor cables should be routed in a way that minimizes interference with low-level control and communication wiring.

Grounding and bonding should be designed as part of the complete electrical system rather than added after installation.

20. Five Popular Models From the Same Brand

The following five models represent other commonly used products from the same brand and are useful for comparison.

They are not direct replacements for the 690 VAC, 200 kW 20G14NF212JN0NNNNN. Their voltage classes, power levels, and physical designs are different.

21. Related AC-Input Version

Another related configuration is the 20G1ANF212JN0NNNNN.

This model has the same general 212 A / 200 kW Normal Duty and 171 A / 160 kW Heavy Duty power level and is also a Frame 7, 690 VAC PowerFlex 755 drive.

The important difference is the input arrangement.

The requested 20G14NF212JN0NNNNN uses DC input with precharge, while the 20G1ANF212JN0NNNNN is an AC-input-with-precharge configuration without DC terminals.

This distinction is extremely important when designing a replacement because the two models should not be treated as mechanically or electrically identical simply because the current and kW ratings are similar.

22. Catalog Number Breakdown

The catalog number provides useful information about the drive configuration.

The 20G designation identifies the PowerFlex 755 family.

The 14 section corresponds to the DC-input-with-precharge configuration.

The NF section identifies the 690 VAC configuration.

The 212 portion identifies the 212 A Normal Duty rating.

The J portion identifies the filtered / CM jumper configuration.

The N braking designation indicates that the internal dynamic braking transistor is not included.

The 0 identifies the blank/no-HIM configuration.

Catalog Number Section	General Meaning
20G	PowerFlex 755 family
14	DC Input with Precharge
NF	690 VAC configuration
212	212 A Normal Duty rating
J	Filtered / CM Jumper Installed
N	No Internal Dynamic Braking Transistor
0	Blank / No HIM
NNNNN	No additional selected options in those positions

---

23. Why the 212 A Rating Is Important

The 212 A rating places this model in a high-power industrial category.

At this size, drive selection should be based on a complete motor and load study.

The following items should be checked:

• Motor nameplate voltage.
• Motor full-load current.
• Motor power.
• Motor service factor.
• Required overload.
• Acceleration time.
• Deceleration time.
• Operating speed range.
• Load inertia.
• Starting torque.
• Continuous operating duty.
• Ambient temperature.
• Installation altitude.
• Cabinet cooling.
• Braking requirements.

The drive should not be selected solely because the motor is labeled “200 kW.”

---

24. Applications Where JN0 Is a Good Fit

The JN0 version is especially suitable for applications where the load does not require dynamic braking.

Examples include large centrifugal pumps with normal deceleration requirements.

Large fans and blowers can also be suitable because they typically have predictable load behavior.

Some continuous process machinery can benefit from the same configuration when rapid braking is not required.

Large compressors may also use this configuration depending on the compressor design and deceleration requirements.

The important factor is the actual mechanical behavior of the machine.

---

25. Applications Requiring Additional Braking Evaluation

Some applications deserve additional attention before choosing JN0.

These include:

• High-inertia centrifuges.
• Rapid-stop conveyors.
• High-speed rotating machinery.
• Winders and unwinders.
• Certain hoisting systems.
• Large machine tools.
• Rapid-cycle machinery.
• Machinery with frequent deceleration.

In these applications, the amount of regenerative energy can be significant.

If dynamic braking is required, the JA0 version should be evaluated instead.

---

26. Maintenance Considerations

The cooling system should be included in the maintenance schedule.

Fans, ventilation passages, cabinet filters, and surrounding airflow paths should be inspected periodically.

Dust accumulation can reduce cooling efficiency and increase operating temperature.

Electrical connections should also be inspected as part of normal preventive maintenance.

High-power connections should remain secure and properly torqued according to the applicable installation requirements.

Network connections and control wiring should also be checked if the drive is part of a large automated system.

27. Advantages for System Integrators

For system integrators, the PowerFlex 755 platform offers a useful combination of high power capability and industrial communication.

The embedded Ethernet/IP capability allows the drive to fit naturally into PLC-based automation systems.

The common drive architecture also helps engineering teams standardize programming, diagnostics, commissioning, and maintenance practices.

The 690 VAC rating is particularly useful when the facility already uses high-voltage motor distribution.

28. Advantages for Machine Builders

Machine builders can benefit from the scalable PowerFlex 755 platform.

Different motor sizes can be accommodated using closely related catalog numbers.

This can reduce the number of completely different drive platforms that an engineering team needs to support.

For a machine that does not need dynamic braking, the JN0 configuration provides a straightforward solution at the 200 kW Normal Duty level.

If braking requirements change, the JA0 version provides a closely related alternative with the internal braking transistor.

29. Advantages for End Users

For end users, the major advantage is controlled operation of large industrial motors.

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

The integrated network capability can also improve access to operating information and diagnostics.

For a plant with multiple PowerFlex 755 installations, standardizing on the same family can simplify training and maintenance.

31. Direct Technical Comparison With Nearby Models

The 171 A model is one step below the requested drive.

It provides 160 kW Normal Duty and 132 kW Heavy Duty.

The 212 A model increases the Normal Duty rating to 200 kW.

The 263 A model increases the Normal Duty rating again to 250 kW.

This makes the 212 A model a useful middle choice when a 171 A drive is too small but a 263 A drive would provide unnecessary capacity.

Model / Part Number	ND Current	ND Power	HD Current	HD Power	Frame	Dimensions	Weight
20G14NF171JN0NNNNN	171 A	160 kW	142 A	132 kW	7	430 × 881.5 × 349.6 mm	72.6–108.9 kg
20G14NF212JN0NNNNN	212 A	200 kW	171 A	160 kW	7	430 × 881.5 × 349.6 mm	72.6–108.9 kg
20G14NF263JN0NNNNN	263 A	250 kW	212 A	200 kW	7	430 × 881.5 × 349.6 mm	72.6–108.9 kg

34. Final Recommendation

The Allen-Bradley 20G14NF212JN0NNNNN is a strong choice for a 690 VAC, three-phase, approximately 200 kW Normal Duty motor application where a PowerFlex 755 architecture is preferred and the machine does not require an internal dynamic braking transistor.

Its combination of 212 A Normal Duty capacity, 171 A Heavy Duty capacity, 690 VAC operation, Frame 7 construction, forced-air cooling, Ethernet/IP integration, filtered configuration, and DC input with precharge makes it suitable for large industrial process and machine applications.

The most important selection point is the JN0 braking configuration.

If the application has normal acceleration and deceleration requirements and does not require an internal dynamic braking transistor, JN0 is a practical configuration.

If the machine has substantial regenerative energy or requires frequent rapid deceleration, the 20G14NF212JA0NNNNN should be considered instead because it includes the internal dynamic braking transistor.

For lower-power applications, the 20G14NF171JN0NNNNN, 20G14NF142JN0NNNNN, and 20G14NF119JN0NNNNN provide smaller alternatives within the same 690 VAC PowerFlex 755 family.

For higher-power requirements, the 20G14NF263JN0NNNNN provides the next higher rating at approximately 250 kW Normal Duty.

In practical terms, the 20G14NF212JN0NNNNN sits in a useful position within the 690 VAC PowerFlex 755 range: it is large enough for serious industrial machinery, but it remains within the established Frame 7 architecture used by nearby 160 kW and 250 kW-class models.

The product is therefore particularly well suited to large pumps, fans, blowers, compressors, conveyors, process machinery, mixers, material-handling equipment, and other industrial systems requiring reliable high-power variable-speed motor control.
