Allen-Bradley 20G14NF119JN0NNNNN – PowerFlex 755 Air-Cooled AC Drive

1. Product Overview

The Allen-Bradley 20G14NF119JN0NNNNN is a high-power PowerFlex 755 AC Drive designed for large industrial motor-control applications.

This model is rated for a 690 VAC, three-phase system and uses a DC input with precharge configuration. It provides a 119 A Normal Duty output rating, corresponding to a 110 kW Normal Duty power rating. Under Heavy Duty operation, the drive is rated at approximately 98 A and 90 kW.

The unit is an air-cooled, open-type, Frame 6 drive. It is designed primarily for installation inside an appropriate electrical cabinet or industrial control enclosure where suitable ventilation, grounding, environmental protection, and service access can be provided.

One of the most important characteristics of the 20G14NF119JN0NNNNN is its JN0 configuration. Unlike the JA0 version of the same current and voltage class, this model has no internal dynamic braking transistor and no internal dynamic braking resistor. This distinction is important when replacing an existing drive or selecting a drive for a braking-intensive machine.

The drive is supplied with filtering and the CM jumper installed, and it has a blank configuration with no HIM. The unit also provides embedded Ethernet communication capability, making it suitable for integration into a larger industrial automation network.

The model belongs to the PowerFlex 755 series within the PowerFlex 750-Series family. It is positioned toward higher-power industrial applications rather than small standalone machinery.

4. Electrical Rating

The 20G14NF119JN0NNNNN is a high-capacity drive with a 119 A Normal Duty output rating.

Its Normal Duty power rating is 110 kW, making it suitable for large industrial motors where a smaller PowerFlex drive would not provide sufficient continuous current.

The Heavy Duty rating is approximately 98 A / 90 kW.

Operating Duty	Output Current	Power Rating	Typical Load Type
Normal Duty	119 A	110 kW	Pumps, fans, blowers, conveyors and other normal industrial loads
Heavy Duty	98 A	90 kW	Higher-load applications requiring greater overload capability

The difference between Normal Duty and Heavy Duty should be taken seriously when selecting the drive.

A motor should not be selected solely according to its kW rating. Motor nameplate current, load torque, acceleration requirements, overload profile, operating speed, inertia, duty cycle, and ambient conditions can all affect the final drive size.

For a variable-torque pump or fan, the 110 kW Normal Duty rating may be the relevant selection point.

For a demanding constant-torque machine, the 90 kW Heavy Duty rating may be more important.

5. 690 VAC / 932 VDC Electrical System

The drive is designed for a 690 VAC three-phase industrial system.

The associated DC-link voltage class is approximately 932 VDC.

This high-voltage architecture is particularly relevant to large industrial installations where motors and electrical distribution systems operate at higher voltage levels.

Using a higher voltage for large motor systems can help reduce current for a given power level. However, the complete electrical system must be designed around the voltage class.

The incoming power system, motor, cables, protective equipment, disconnecting equipment, grounding system, and cabinet insulation requirements all need to be compatible with the installation.

The 932 VDC figure is especially important when the drive is used as part of a common DC-bus system. It should not be treated simply as another standard 480 VAC drive.

6. DC Input with Precharge

The 20G14NF119JN0NNNNN uses a DC input with precharge configuration.

This makes the drive particularly useful in applications where a DC bus is already available.

A common DC-bus system can be used where multiple drives share a common power architecture. This type of arrangement can be useful in large machines and production systems containing several motor drives.

The precharge function controls the initial charging of the drive’s DC-link capacitors.

Without appropriate precharge control, the initial energization of large capacitors can produce a very high inrush current.

The precharge arrangement therefore contributes to controlled energization and helps protect the DC-link charging circuit.

7. Dynamic Braking Configuration

The JN0 configuration has no dynamic braking transistor and no internal braking resistor.

This is one of the most important differences between this model and certain other PowerFlex 755 configurations.

Dynamic Braking Item	20G14NF119JN0NNNNN
Dynamic Braking	None
Internal Braking Transistor	No
Internal Braking Resistor	No
External Braking Resistor	Not directly supported through an internal DB transistor
Best Suited For	Applications where internal dynamic braking is not required

This means that the drive should not be selected on the assumption that it has the same braking functionality as a JA0-configured model.

If the application requires rapid deceleration or significant regenerative braking energy dissipation, the overall drive architecture should be reviewed carefully.

For applications involving large inertia, rapid stopping, downhill loads, high-speed deceleration, or frequent braking cycles, the braking strategy should be established during the engineering stage.

8. JN0 Versus JA0

A particularly useful comparison is between the following two models:

20G14NF119JN0NNNNN

and

20G14NF119JA0NNNNN

They share the same basic current and voltage class, but their braking configurations are different.

Feature	20G14NF119JN0NNNNN	20G14NF119JA0NNNNN
Voltage	690 VAC	690 VAC
Normal Duty Current	119 A	119 A
Normal Duty Power	110 kW	110 kW
Heavy Duty Current	98 A	98 A
Heavy Duty Power	90 kW	90 kW
Input	DC with Precharge	DC with Precharge
Frame	Frame 6	Frame 6
Cooling	Air Cooled	Air Cooled
Enclosure	Open Type	Open Type
Filtering	Filtered	Filtered
CM Jumper	Installed	Installed
HIM	Blank / No HIM	Blank / No HIM
Dynamic Braking Transistor	None	Included
Internal Braking Resistor	None	None

The JN0 version is therefore appropriate when the application does not require the internal dynamic braking transistor.

The JA0 version is the more appropriate configuration when the system requires an internal braking transistor for an external braking resistor.

This distinction can become critical during replacement projects. Matching only the voltage and current is not always enough; the complete catalog number should be compared.

9. Air-Cooled Construction

The drive uses an air-cooled design.

For an industrial drive in the 110 kW range, thermal management is an important part of installation planning.

The drive generates heat during normal operation due to semiconductor conduction losses, switching losses, control electronics, and other internal losses.

The cabinet therefore needs sufficient airflow and adequate heat dissipation.

The surrounding enclosure should be designed so that hot air is not trapped around the drive.

Environmental conditions also matter. High ambient temperature, dust, poor ventilation, excessive humidity, and contaminated cooling paths can all reduce long-term reliability.

10. Open-Type Enclosure

The 20G14NF119JN0NNNNN is an open-type drive.

It is intended to be incorporated into a suitable electrical cabinet or control enclosure rather than being installed directly in an exposed industrial environment.

The surrounding cabinet provides the environmental protection required by the actual installation.

Depending on the application, the cabinet may also contain:

• Main disconnect equipment.
• Input protection.
• DC-bus equipment.
• Control power supplies.
• PLC equipment.
• Network switches.
• External braking or energy-management equipment where applicable.
• Terminal blocks.
• Motor protection components.
• Safety equipment.
• Cooling and ventilation equipment.

The cabinet must be designed as a complete electrical system rather than simply treating the drive as a standalone box.

11. Filtering and CM Jumper

The model is configured as Filtered, CM Jumper Installed.

Filtering is important in variable-frequency drive applications because high-frequency switching can create electromagnetic noise.

Proper filtering, grounding, bonding, and motor-cable installation help reduce unwanted electrical interference.

The CM jumper configuration is also relevant to common-mode noise management and the overall grounding architecture.

For larger industrial installations, the drive, cabinet, motor, motor cable, grounding system, and network wiring should be treated as one electrical system.

Good installation practice is often just as important as the drive’s internal filtering hardware.

12. HIM Configuration

The drive is supplied with a Blank / No HIM configuration.

HIM means Human Interface Module.

A no-HIM configuration is practical for systems where local operation is not the primary control method.

Instead, the drive can be controlled through a PLC, HMI, DCS, SCADA system, or networked control architecture.

This arrangement is common in centralized industrial automation systems where operators interact with the machine through a plant-level HMI rather than directly through the drive itself.

13. Ethernet Communication

The drive includes embedded Ethernet capability.

This provides a convenient communication path between the drive and the larger automation system.

Typical information exchanged through a networked drive installation can include:

• Start commands.
• Stop commands.
• Speed references.
• Frequency references.
• Motor current.
• Output frequency.
• Drive status.
• Warning information.
• Fault information.
• Diagnostic information.
• Operating parameters.
• Process-related information.

This can significantly simplify centralized monitoring when multiple drives are installed throughout a production line.

14. Product Applications

Large Pumps

Large pumps are one of the most suitable applications for a drive in this power range.

Examples include:

• Industrial water circulation.
• Cooling-water pumps.
• Process pumps.
• Water-treatment equipment.
• Large booster pumps.
• Industrial fluid-transfer systems.

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

This can provide better process control than operating a large motor continuously at a fixed speed.

Large Fans

The drive can also be used for large fans and blowers.

Potential applications include:

• Industrial ventilation.
• Furnace ventilation.
• Exhaust systems.
• Dust collection.
• Cooling systems.
• Process-air systems.

Large fan motors can require substantial starting and running current, making a high-capacity drive appropriate for these applications.

Conveyors

The drive is well suited to large conveyor systems.

A controlled acceleration profile can reduce mechanical shock and help prevent sudden loading of belts, gearboxes, couplings, and other mechanical components.

Potential applications include:

• Bulk-material conveyors.
• Mining-related conveyors.
• Manufacturing lines.
• Packaging systems.
• Material-transfer systems.
• Warehouse equipment.

Compressors

Large industrial compressors can also require a drive in this capacity range.

The drive can provide controlled motor speed and can be integrated with a larger automation system.

Compressor applications should be evaluated carefully because the actual torque and speed characteristics can vary significantly between compressor designs.

Blowers

Large industrial blowers often benefit from adjustable speed.

The drive can be used in:

• Air-handling systems.
• Industrial process ventilation.
• Combustion-air systems.
• Dust extraction.
• Gas-handling equipment.
• Process-air equipment.

Mixers and Agitators

Large mixers and agitators may require substantial continuous motor current and controlled acceleration.

The drive’s 119 A Normal Duty capacity provides a considerable motor-control range for large process equipment.

Material Handling

Large material-handling systems can also use this drive.

Examples include:

• Transfer equipment.
• Bulk handling.
• Feeding systems.
• Large conveyors.
• Production-line machinery.
• Heavy industrial handling equipment.

Process Machinery

The PowerFlex 755 platform is also appropriate for engineered process machinery where speed control and network integration are important.

The drive can become part of a larger automation system rather than operating as an isolated frequency converter.

15. Main Product Advantages

High 110 kW Normal Duty Capacity

The most obvious advantage is the high power rating.

At 110 kW Normal Duty, the drive can handle large industrial motors that are beyond the range of many compact variable-frequency drives.

690 VAC Capability

The 690 VAC rating makes the unit suitable for high-voltage industrial motor systems.

This is particularly useful in facilities where 690 VAC distribution is already established.

DC-Bus Compatibility

The DC input and precharge architecture provide flexibility for common-DC-bus applications.

This can be valuable when multiple drives are integrated into a coordinated power system.

Ethernet Integration

Embedded Ethernet capability allows the drive to be incorporated into a networked automation system.

Operators and control systems can obtain drive status and operating information without relying solely on local interaction.

No Unnecessary Dynamic-Braking Hardware

For applications that do not require dynamic braking, the JN0 configuration avoids paying for an internal braking transistor that the application may not need.

This can make it a sensible choice for applications with controlled deceleration requirements that do not depend on a dedicated dynamic-braking resistor system.

Frame 6 Industrial Construction

The Frame 6 architecture provides a substantial physical and electrical platform suitable for large industrial applications.

It is designed for cabinet integration and engineered machine installations.

Air Cooling

Air cooling provides a practical solution for high-power industrial applications without introducing the complexity of liquid cooling.

Open Cabinet Integration

The open-type configuration provides flexibility for system integrators.

The drive can be combined with other control, protection, networking, and power-distribution components inside a properly engineered cabinet.

16. Dimensions and Weight

For mechanical planning, the drive is associated with a Frame 6 construction.

A practical reference size is approximately:

665.5 mm high × 308 mm wide × 346.4 mm deep

18. Recommended Same-Series Models

The following models are useful alternatives within the same PowerFlex 755 / 690 VAC DC-input family.

Model / Part Number	Voltage	Normal Duty Current	Normal Duty Power	Heavy Duty Current	Heavy Duty Power	Frame / Position
20G14NF061JN0NNNNN	690 VAC	61 A	55 kW	50 A	45 kW	Lower capacity
20G14NF082JN0NNNNN	690 VAC	82 A	75 kW	61 A	55 kW	Lower capacity

20G14NF171JN0NNNNN	690 VAC	171 A	160 kW	142 A	132 kW	Larger capacity / Frame 7

The 20G14NF098JN0NNNNN is particularly useful when the required motor current is below the 119 A rating.

The 20G14NF142JN0NNNNN is the natural next step when the motor requires more current than the 119 A model can provide.

The 20G14NF171JN0NNNNN moves into a still higher power range and is associated with the larger Frame 7 class.

19. Same-Series Power Comparison

Model / Part Number	Normal Duty Current	Normal Duty Power	Heavy Duty Current	Heavy Duty Power
20G14NF061JN0NNNNN	61 A	55 kW	50 A	45 kW
20G14NF082JN0NNNNN	82 A	75 kW	61 A	55 kW

20G14NF119JN0NNNNN	119 A	110 kW	98 A	90 kW
20G14NF142JN0NNNNN	142 A	132 kW	119 A	110 kW
20G14NF171JN0NNNNN	171 A	160 kW	142 A	132 kW

The 119 A model sits near the middle of this larger-capacity group.

It provides a useful balance between the 90 kW Normal Duty class and the 132 kW Normal Duty class.

20. Five Popular Same-Brand Models

The following models are useful related products when comparing different motor sizes and applications.

Model / Part Number	Series	Voltage Class	Current Class	Approx. Power Class	Cooling	Typical Application
25B-D017N114	PowerFlex 525	480 VAC class	17 A class	Approx. 7.5 kW class	Air Cooled	Compact machines, pumps, fans
25B-D024N114	PowerFlex 525	480 VAC class	24 A class	Approx. 11 kW class	Air Cooled	General industrial machinery
25B-D030N114	PowerFlex 525	480 VAC class	30 A class	Approx. 15 kW class	Air Cooled	Machinery and process control

20G11NC072JA0NNNNN	PowerFlex 755	480 VAC class	72 A class	Approx. 55 kW class	Air Cooled	Larger pumps, fans and machinery

The PowerFlex 525 models are generally better suited to compact and medium-size machines.

The PowerFlex 755 models are designed for more demanding applications where higher motor power, greater control flexibility, and advanced system integration are required.

21. Popular Model Mechanical Comparison

Exact physical dimensions and weights can vary with frame size, voltage class, configuration, and installed options. Therefore, the following table is intended as a product-selection reference.

Model / Part Number	Series	Size Class	Dimensions	Weight
25B-D017N114	PowerFlex 525	Frame-dependent	Configuration dependent	Configuration dependent
25B-D024N114	PowerFlex 525	Frame-dependent	Configuration dependent	Configuration dependent
25B-D030N114	PowerFlex 525	Frame-dependent	Configuration dependent	Configuration dependent
20G11NC5P0JA0NNNNN	PowerFlex 755	Frame-dependent	Configuration dependent	Configuration dependent
20G11NC072JA0NNNNN	PowerFlex 755	Frame-dependent	Configuration dependent	Configuration dependent

For a purchasing specification, these models should be checked against the exact required frame and option configuration before final mechanical planning.

22. Application Selection Guide

Application	Recommended Consideration
Large Pump	Normal Duty rating, motor current, variable-torque characteristics
Large Fan	Normal Duty rating and thermal conditions
Blower	Continuous current and operating speed range
Conveyor	Starting torque, acceleration, deceleration and load inertia
Compressor	Motor current, torque profile and speed range
Mixer	Heavy Duty requirements and overload characteristics
Material Handling	Torque, acceleration and stopping requirements
Process Machinery	Network integration, speed control and diagnostics
Common DC-Bus System	DC input and precharge configuration
Braking-Intensive System	Review JN0 configuration carefully because no internal DB transistor is included

The last point is particularly important.

The 20G14NF119JN0NNNNN is not the configuration to select simply because the motor is 110 kW. If the machine has substantial regenerative energy during deceleration, the braking arrangement needs to be reviewed separately.

23. Motor Selection Considerations

The motor should be checked against the drive’s current rating rather than simply comparing kW values.

The following information should be available before final selection:

• Motor rated voltage.
• Motor rated current.
• Motor rated frequency.
• Motor rated speed.
• Motor power.
• Service factor.
• Load type.
• Starting torque.
• Continuous torque.
• Acceleration time.
• Deceleration time.
• Inertia.
• Required speed range.
• Ambient temperature.
• Altitude.
• Duty cycle.

A 110 kW motor is not automatically suitable simply because the drive is rated at 110 kW.

The motor’s actual nameplate current and operating conditions determine whether the drive provides adequate capacity.

24. Cabinet Design Considerations

Because the drive is open type, cabinet design is an important part of the installation.

The cabinet should provide:

• Appropriate electrical protection.
• Adequate ventilation.
• Sufficient drive clearance.
• Proper grounding.
• Suitable cable routing.
• Separation of power and control wiring where appropriate.
• Adequate access for maintenance.
• Protection against excessive dust and moisture.
• Suitable ambient temperature control.

The heat generated by a large drive should be included in the cabinet thermal calculation.

If several drives are installed inside one cabinet, their combined heat output can become significant.

25. Maintenance

Regular inspection can help prevent unexpected drive shutdowns.

Maintenance activities can include:

• Checking cooling airflow.
• Inspecting ventilation paths.
• Removing excessive dust.
• Inspecting electrical connections.
• Checking grounding connections.
• Reviewing fault history.
• Checking cabinet temperature.
• Inspecting motor cables.
• Checking network connections.
• Inspecting cooling fans.
• Verifying that environmental conditions remain acceptable.

For a high-power industrial drive, maintenance should be considered part of the overall equipment reliability strategy rather than an occasional corrective task.

26. Advantages for Industrial Automation

The 20G14NF119JN0NNNNN is particularly useful in centralized automation architectures.

Its Ethernet capability allows the drive to become part of the control network.

The PLC or higher-level controller can issue commands and receive operating information.

This can reduce the need for extensive hardwired status signals and provide operators with more detailed drive information.

For a production line containing many motors, centralized monitoring can make troubleshooting considerably easier.

27. Product Position Within the PowerFlex 755 Family

The model can be positioned as follows:

PowerFlex 755 → 690 VAC DC-input family → Frame 6 → 119 A Normal Duty → 110 kW Normal Duty → JN0 configuration

This gives a useful way to distinguish the product from visually similar models.

For example, the catalog number contains information about voltage class, current range, configuration, and option selection.

When ordering a replacement, the complete catalog number should be retained whenever possible.

29. Overall Product Assessment

The Allen-Bradley 20G14NF119JN0NNNNN is a high-capacity PowerFlex 755 air-cooled AC drive designed for large industrial motor applications.

Its 119 A Normal Duty / 110 kW rating provides substantial motor-control capacity, while the 98 A / 90 kW Heavy Duty rating gives a separate selection point for applications with more demanding load characteristics.

The 690 VAC electrical class makes it appropriate for high-voltage industrial motor systems, while the 932 VDC-class DC input with precharge configuration provides flexibility for common DC-bus applications.

The drive’s Frame 6 open-type construction is suitable for integration into a properly engineered industrial cabinet.

Its filtered configuration with CM jumper installed helps support the electrical-noise management requirements associated with high-power variable-frequency drive systems.

The embedded Ethernet capability is another practical advantage for modern factories, particularly where several drives must be controlled and monitored from a central automation system.

The most important limitation to remember is the JN0 dynamic-braking configuration. This model has no internal dynamic braking transistor and no internal braking resistor. It should therefore be selected with a clear understanding of the machine’s deceleration and regenerative-energy requirements.

For applications such as large pumps, fans, blowers, conveyors, compressors, mixers, material-handling equipment, and process machinery that do not require the internal dynamic-braking transistor, the 20G14NF119JN0NNNNN provides a strong combination of high power capacity, 690 VAC operation, DC-bus capability, network integration, and cabinet-based industrial construction.

In short, the 20G14NF119JN0NNNNN is a 690 VAC, three-phase, 119 A Normal Duty, 110 kW Normal Duty, 98 A Heavy Duty, 90 kW Heavy Duty, Frame 6, air-cooled PowerFlex 755 AC drive with DC input and precharge, filtered configuration, CM jumper installed, blank/no HIM, embedded Ethernet capability, and no internal dynamic braking transistor.

For replacement projects, purchasing, and engineering work, the complete catalog number 20G14NF119JN0NNNNN should be specified rather than identifying the unit only as a “PowerFlex 755 110 kW drive.” The JN0 suffix represents a meaningful functional configuration and can affect the braking design of the finished machine.
