The Allen-Bradley 20F11RC015JA0NNNNN is a PowerFlex 753 AC Drive designed for three-phase industrial motor control.
This model is a 400 VAC-class, 15.4 A normal-duty, 7.5 kW normal-duty drive with an 11.5 A heavy-duty rating and 5.5 kW heavy-duty capacity.
It is an air-cooled, open-type Frame 1 drive with embedded I/O, EMC filtering, an internal dynamic-braking transistor, AC input with precharge and DC terminals.
The exact JA configuration is also important because the common-mode capacitor jumper is installed.
This configuration is closely related to the AA version, but the two should not be treated as identical catalog configurations when selecting a replacement.
The drive is particularly well suited to industrial machinery where the motor speed needs to be adjustable and where controlled acceleration, controlled deceleration, PLC integration and reliable motor control are important.
Typical applications include conveyors, pumps, fans, blowers, feeders, packaging machines, material-handling systems, processing equipment and general industrial machinery.

The electrical ratings should always be checked against the actual motor nameplate current.
Horsepower is useful for initial selection, but motor current, duty cycle, overload requirement and mechanical load are more important when determining whether a particular drive is suitable.

| Brand | Allen-Bradley |
| Product Family | PowerFlex |
| Product Series | PowerFlex 753 |
| Product Category | Industrial AC Drives |
| Drive Type | Variable Frequency Drive |
| Main Purpose | Three-phase AC motor speed and torque control |
| Typical Installation | Industrial control cabinet |
| Typical Users | Machine builders, OEMs, system integrators and industrial maintenance teams |
The PowerFlex 753 series is designed around industrial AC motor control.
It provides considerably more functionality than a simple contactor-based motor starter because it can regulate motor speed and provide programmable acceleration and deceleration.
The series also supports different current and power ratings, allowing related drives to be used across different machine sizes.
This is particularly convenient for OEMs that manufacture several versions of the same machine.
The 20F11RC015JA0NNNNN can be viewed as the electronic power-control stage between an automation controller and a three-phase motor.
A typical machine arrangement is:
PLC / Controller
↓
Speed / Start / Stop Command
↓
PowerFlex 753 Drive
↓
Three-Phase AC Motor
↓
Gearbox / Mechanical Transmission
↓
Machine Load
The PLC or machine controller determines what the motor needs to do.
The drive then converts that command into a controlled electrical output.
Instead of simply switching the motor between ON and OFF, the drive can control the motor’s operating speed.
This makes the system much more flexible.
For example, a conveyor may need to operate slowly during loading and faster during normal production.
A pump may need to change speed according to process demand.
A fan may need to increase speed when temperature rises.
A packaging machine may need to accelerate and decelerate repeatedly during each production cycle.
These are exactly the kinds of applications where a variable-frequency drive becomes valuable.
The 7.5 kW normal-duty rating is one of the defining characteristics of this model.
The drive provides a 15.4 A continuous normal-duty output.
This makes it suitable for many motors in the approximately 10 HP class, provided the actual motor nameplate current remains within the applicable drive rating.
The 7.5 kW capacity also makes this model an important step above the 5.5 kW PowerFlex 753 configuration.
For equipment manufacturers, this provides a convenient way to standardize the drive family while moving to a larger motor.
Under heavy-duty conditions, the drive is rated for approximately:
11.5 A continuous
and
5.5 kW
The heavy-duty rating is important for applications where the motor experiences greater torque demand or more severe operating conditions.
Examples can include:
The actual load profile should be evaluated before selecting normal-duty or heavy-duty operation.
| Duty Mode | Continuous Current | 1-Minute Current | 3-Second Current | Power Rating | Approx. HP |
|---|---|---|---|---|---|
| Normal Duty | 15.4 A | 16.9 A | 23.1 A | 7.5 kW | 10 HP |
| Heavy Duty | 11.5 A | 12.7 A | 17.3 A | 5.5 kW | 7.5 HP |
The normal-duty rating is generally the better reference for applications with relatively moderate overload requirements.
The heavy-duty rating should be used when the application has a more demanding torque profile.
It is important not to assume that a 7.5 kW motor automatically qualifies for the heavy-duty rating simply because the horsepower number appears similar.
The motor’s actual current and application load must be evaluated.
The drive belongs to the 400 VAC three-phase class.
It is intended for industrial power systems in the approximate 380–480 VAC range, subject to the specific installation and drive configuration.
This makes it suitable for many industrial facilities using 400 V or 415 V three-phase systems.
Typical applications include:
Before installation, the supply voltage and motor voltage should always be checked.
The drive uses a Frame 1 mechanical design.
This is significant because it allows the drive to provide 15.4 A normal-duty capacity while maintaining a relatively compact physical package.
Approximate dimensions are:
400.5 mm × 110 mm × 211 mm
Approximate weight:
6.0 kg
The narrow approximately 110 mm width can be especially useful in control cabinets where several drives and automation components must fit into a limited space.
| Mechanical Parameter | Specification |
|---|---|
| Model | 20F11RC015JA0NNNNN |
| Frame Size | Frame 1 |
| Height | 400.5 mm |
| Width | 110 mm |
| Depth | 211 mm |
| Approx. Weight | 6.0 kg |
| Enclosure | Open Type |
| IP Rating | IP20 |
| Cooling | Forced Air |
| Mounting | Panel / Cabinet |
The dimensions above represent the approximate drive body dimensions.
They should not be interpreted as the total cabinet space required.
The installation should provide additional room for power cables, control wiring, grounding conductors, airflow and maintenance access.
The approximate 6.0 kg weight should also be considered when designing the mounting panel.
The drive uses forced-air cooling.
During operation, the power semiconductors generate heat.
The internal cooling system moves air through the drive to remove this heat.
For reliable operation, the surrounding cabinet needs sufficient airflow.
Particular attention should be paid to:
When multiple drives are installed inside the same cabinet, their combined thermal load should be considered.
A cabinet that is too hot can reduce the operating margin of the drive and shorten component life.
The IP20 open-type design means that the drive is normally installed inside a suitable electrical enclosure.
The drive itself is not intended to function as a fully sealed outdoor enclosure.
The surrounding cabinet should provide the environmental protection required by the machine.
This is particularly important in areas with:
The cabinet should be designed to maintain appropriate temperature and cleanliness.
The 20F11RC015JA0NNNNN uses a filtered EMC configuration.
AC drives use high-frequency switching to regulate the motor output.
This switching operation can generate electromagnetic disturbances.
The filtering arrangement helps reduce certain conducted noise components.
However, good EMC performance depends on the complete installation.
Important installation practices include:
The drive’s EMC filter should therefore be considered part of a complete EMC strategy rather than a substitute for proper installation.
The JA configuration is a particularly important feature of this exact model.
For:
20F11RC015JA0NNNNN
the common-mode capacitor jumper is installed.
This differs from the closely related:
20F11RC015AA0NNNNN
where the jumper is removed.
| Model | CM Capacitor Jumper |
|---|---|
| 20F11RC015JA0NNNNN | Installed |
| 20F11RC015AA0NNNNN | Removed |
The main motor-current and power ratings are essentially the same between these two configurations.
However, the common-mode capacitor configuration is important for system grounding and electrical compatibility.
When replacing a drive, the complete catalog number should therefore be checked rather than selecting a unit based only on kW and current.
The drive includes an internal dynamic-braking transistor.
This is useful when the motor needs controlled or relatively rapid deceleration.
During deceleration, the motor can return energy to the drive’s DC bus.
This regenerative energy can increase the DC-bus voltage.
A braking resistor can dissipate the excess energy.
The internal braking transistor provides the switching function required to control an external braking resistor.
Typical applications include:
The external resistor itself is not included in the drive.
It must be selected according to the braking energy, resistance requirements and duty cycle of the machine.
The drive includes embedded I/O.
This is useful because basic machine-control signals can be connected directly to the drive.
Depending on the system architecture, typical signals can include:
For a relatively simple machine, embedded I/O can reduce the need for additional interface components.
For a larger machine, the drive can become part of a PLC-based automation system.
The model uses a Blank / No HIM configuration.
HIM stands for Human Interface Module.
A local HIM can be useful during commissioning and troubleshooting, but it is not necessary for every machine.
Many OEM machines use a dedicated touchscreen HMI.
In such a machine, the operator interacts with the HMI while the drive remains inside the electrical cabinet.
The blank/no-HIM configuration can therefore be a practical choice for automated machinery.
Conveyor systems are one of the most common applications for variable-frequency drives.
The drive can adjust conveyor speed according to production requirements.
For example, a production line may require:
Slow Speed → Loading
Medium Speed → Processing
High Speed → Normal Production
The drive can provide these speed changes electronically.
Controlled acceleration can also reduce sudden mechanical loading.
This can be beneficial for belts, chains, gearboxes, shafts and couplings.
The 20F11RC015JA0NNNNN can be used in suitable industrial pump applications.
Typical examples include:
The motor speed can be adjusted according to the required flow or pressure.
For suitable centrifugal-pump applications, reducing speed can also provide energy-saving opportunities.
The pump curve and process requirements should always be considered when establishing the operating range.
Industrial fans and blowers often need variable airflow.
Running a fan continuously at full speed is not always necessary.
The drive can adjust motor speed according to:
Typical applications include:
Packaging equipment often has repeated motion cycles.
A typical sequence might be:
Start
↓
Accelerate
↓
Run at Production Speed
↓
Decelerate
↓
Stop
↓
Repeat
The drive can provide programmable acceleration and deceleration.
This can improve the smoothness of the machine’s motion.
Where rapid stopping is required, the dynamic-braking transistor can also be useful when combined with an appropriately selected external braking resistor.
Material-handling applications can involve heavy loads.
A heavily loaded conveyor can place significant mechanical stress on the drive train when starting abruptly.
Controlled acceleration allows the motor to increase speed gradually.
This can help reduce sudden mechanical shock on:
The heavy-duty rating should be evaluated carefully for applications with high starting torque.
Industrial feeders frequently require adjustable speed.
The feed rate can be modified according to production demand.
Potential applications include:
The drive can receive speed commands through its available I/O or the machine’s broader automation architecture.
Mixers can present a challenging starting condition because the material inside the mixer may create substantial resistance.
The drive can provide controlled acceleration rather than applying the full operating condition immediately.
This can be useful for:
The application should be evaluated according to actual torque requirements.
The drive can also be used for many general industrial applications where the motor current and duty cycle remain within its ratings.
Potential uses include:
The 15.4 A continuous normal-duty output gives the drive substantial capacity for medium-size motors.
It provides a useful step above the 11.5 A PowerFlex 753 model.
The 7.5 kW rating makes the drive suitable for many approximately 10 HP-class applications.
This is a common motor size in industrial machinery.
The heavy-duty rating gives the same physical drive another useful application range.
This makes the drive more flexible when the load profile changes.
One of the strongest physical advantages is the Frame 1 package.
The approximate 110 mm width can help reduce cabinet width.
The 400 VAC class makes the drive suitable for many industrial three-phase power systems.
The internal DB transistor provides flexibility for machines requiring controlled stopping.
Embedded I/O can simplify basic machine-control wiring.
The integrated filtering supports a properly designed industrial EMC installation.
The JA configuration provides the installed common-mode capacitor jumper arrangement.
This can be important for matching the intended electrical configuration of the machine.
The blank/no-HIM arrangement is useful for PLC- and HMI-controlled equipment.
For OEM machine builders, the 20F11RC015JA0NNNNN offers a useful combination of electrical capacity and compact mechanical size.
A 15.4 A normal-duty drive can handle a larger motor than the 11.5 A configuration while remaining in the Frame 1 mechanical family.
This can be useful when designing compact machine cabinets.
The PowerFlex 753 platform also allows related drives to be used across different motor sizes.
This can help standardize:
System integrators can benefit from the drive’s combination of embedded functionality and expansion capability.
The drive can be integrated into a wider automation system using the appropriate I/O and communication architecture.
This makes it suitable for both relatively simple standalone motor applications and more sophisticated machine-control systems.
The same general drive platform can also be used across several motor sizes.
That can simplify engineering when a project contains multiple motors.
From a maintenance perspective, a programmable AC drive provides considerably more information than a basic motor starter.
Depending on the system configuration, technicians can monitor:
This information can help separate electrical problems from mechanical problems.
For example, a motor that draws excessive current at low speed may indicate a mechanical loading problem rather than a simple control fault.
The following models are useful related choices within the same PowerFlex 753 family.

These models provide a useful progression from approximately 2.2 kW to 11 kW.
For applications around 7.5 kW, the 20F11RC015JA0NNNNN is the most directly relevant model in this group.
For an application requiring approximately 11 kW, the larger-frame 20F11NC022JA0NNNNN becomes a logical next step.

The 15.4 A model offers considerably more current capacity.
However, using a larger drive than necessary is not always the best solution.
The motor’s actual current and the application duty should be used to determine the appropriate model.
A typical industrial conveyor system could be arranged as:
PLC
↓
Speed Reference
↓
20F11RC015JA0NNNNN
↓
Three-Phase Motor
↓
Gearbox
↓
Conveyor
The PLC can command different speed references depending on production requirements.
The drive then regulates the motor output.
Acceleration and deceleration can be programmed to reduce sudden mechanical loading.
This is especially useful for conveyors carrying heavy or fragile products.
A typical pump system could use:
Pressure Sensor
↓
PLC / Controller
↓
PowerFlex 753
↓
Pump Motor
↓
Pump
The controller adjusts the speed reference according to the required process pressure.
The drive changes motor speed accordingly.
This can provide better process control than operating the pump continuously at full speed.
An industrial fan may be controlled according to temperature.
For example:
Low Temperature → Low Fan Speed
Normal Temperature → Medium Fan Speed
High Temperature → High Fan Speed
The drive can implement the corresponding motor-speed command.
This can improve ventilation control and provide energy-saving opportunities in appropriate applications.
A packaging machine may require hundreds or thousands of motor cycles during production.
The drive can provide controlled acceleration and deceleration for each cycle.
A typical sequence is:
Start
↓
Acceleration
↓
Production Speed
↓
Deceleration
↓
Stop
↓
Repeat
The dynamic-braking transistor can be useful when the machine needs relatively rapid stopping.
Consider a conveyor carrying a heavy load.
If the motor is started at full speed immediately, the mechanical system may experience a large torque shock.
With the drive, the motor can accelerate progressively.
For example:
0% Speed
↓
20% Speed
↓
50% Speed
↓
80% Speed
↓
100% Speed
The exact ramp time depends on the machine.
The result can be smoother mechanical operation.
The approximate drive dimensions are:
400.5 mm H × 110 mm W × 211 mm D
The cabinet should provide additional clearance beyond these dimensions.
The designer should consider:
The drive should also be arranged so that hot air from one drive does not directly enter another drive’s cooling intake.
Before commissioning the drive, the following should be checked.
Confirm that the incoming three-phase supply is compatible with the drive.
Confirm that the motor voltage is suitable for the drive output.
Check the motor nameplate current against the applicable 15.4 A normal-duty or 11.5 A heavy-duty rating.
Confirm the motor’s rated frequency.
Determine whether the machine should be treated as normal duty or heavy duty.
Calculate the braking requirement if the machine needs rapid deceleration.
Because the JA configuration has the CM capacitor jumper installed, grounding and system configuration should be considered carefully.
A well-maintained installation is important for long-term drive performance.
Maintenance personnel should periodically inspect:
The cooling system deserves particular attention.
Dust buildup can reduce airflow and increase operating temperature.
A clean cabinet with adequate ventilation is therefore an important part of drive maintenance.

The final selection should be based on motor nameplate current and actual load characteristics rather than horsepower alone.
The 20F11RC015JA0NNNNN offers a very useful balance between motor capacity and physical size.
It provides 15.4 A normal-duty output and 7.5 kW normal-duty capacity while retaining the relatively compact Frame 1 mechanical design.
This makes it especially attractive for machine builders that need more capacity than the 5.5 kW class but want to avoid moving to a larger physical frame unnecessarily.
The drive also includes several features that are useful in modern industrial machinery.
These include:
The installed common-mode capacitor jumper also makes the JA configuration distinct.
The catalog number 20F11RC015JA0NNNNN contains configuration information rather than being an arbitrary product number.
The number identifies the drive family, voltage class, current/power configuration and option arrangement.
The 20F portion identifies the PowerFlex 753 family.
The 11R portion is associated with the applicable 400 VAC-class Frame 1 configuration.
The C015 portion corresponds to the approximately 15.4 A output class.
The JA portion is especially important because it identifies the filtered configuration with the CM capacitor jumper installed.
The remaining characters define additional factory configuration details.
For replacement work, it is therefore better to use the complete catalog number rather than trying to identify the drive only from its horsepower rating.

The Allen-Bradley 20F11RC015JA0NNNNN is a PowerFlex 753, 400 VAC, three-phase AC drive with a 15.4 A normal-duty output rating and 7.5 kW normal-duty capacity.
Its heavy-duty rating is approximately 11.5 A and 5.5 kW, giving it useful flexibility for both standard industrial motor applications and more demanding load conditions.
The drive’s Frame 1 construction is one of its strongest physical advantages.
With approximate dimensions of 400.5 mm × 110 mm × 211 mm and an approximate weight of 6.0 kg, it offers substantial electrical capacity while remaining relatively compact.
The drive is also well equipped for industrial automation.
The combination of embedded I/O, forced-air cooling, EMC filtering, AC input with precharge, DC terminals and an internal dynamic-braking transistor makes it suitable for a wide range of machine-control applications.
The JA configuration is particularly important.
The common-mode capacitor jumper is installed, which distinguishes this model from the closely related 20F11RC015AA0NNNNN.
The two models have the same basic 15.4 A / 7.5 kW normal-duty and 11.5 A / 5.5 kW heavy-duty ratings, but their common-mode capacitor configurations are different.
For conveyors, pumps, fans, blowers, feeders, packaging machines and material-handling systems, the drive provides adjustable motor speed and controlled acceleration and deceleration.
For machines that need rapid or frequent stopping, the internal dynamic-braking transistor provides the ability to use an appropriately selected external braking resistor.
For OEM machine builders, another major advantage is the ability to remain within the PowerFlex 753 family as motor sizes change.
A smaller machine may use the 20F11RC011JA0NNNNN, while a larger 7.5 kW application can move to the 20F11RC015JA0NNNNN.
For an application requiring approximately 7.5 kW normal-duty motor control on a 400 VAC three-phase system, this model is a particularly useful choice.
In practical terms, the 20F11RC015JA0NNNNN can be summarized as a 15.4 A, 7.5 kW normal-duty, 11.5 A, 5.5 kW heavy-duty, 400 VAC, three-phase, Frame 1 PowerFlex 753 AC drive with embedded I/O, forced-air cooling, IP20 open-type construction, filtered EMC configuration, installed CM capacitor jumper, internal dynamic-braking transistor, AC input with precharge, DC terminals and blank/no-HIM configuration.
Its combination of compact dimensions, substantial current capacity, flexible speed control, dynamic braking capability and industrial automation integration makes it a strong choice for medium-size automated machinery.
