Allen-Bradley 20G1ABE355JN2NNNNN PowerFlex 755 AC Drive

1. Product Introduction

The Allen-Bradley 20G1ABE355JN2NNNNN is a high-power PowerFlex 755 AC Drive designed for demanding industrial motor-control applications where high current capacity, flexible motor control, centralized automation, and reliable operation are required.

The product belongs to the PowerFlex 750-Series and is specifically part of the PowerFlex 755 series.

This model is configured for a 600 VAC, three-phase power system and provides a nominal 355 A output-current rating. Its published motor-duty ratings are approximately 400 HP for Light Duty, 350 HP for Normal Duty, and 300 HP for Heavy Duty.

The drive uses a Frame 8 power structure and a Type 1 / IP20, 600 mm deep MCC-style enclosure. It is an air-cooled, forced-air design intended for large industrial installations rather than compact machine-level applications.

A particularly important feature of this catalog number is the JN2 configuration. Unlike the JN0 version, which is supplied without a HIM, the 20G1ABE355JN2NNNNN includes an Enhanced LCD, Full Numeric, Handheld/Local HIM.

This makes the model suitable for installations where maintenance personnel or operators need direct access to the drive for setup, monitoring, troubleshooting, parameter adjustment, and local operation.

The drive also includes embedded EtherNet/IP, allowing it to be integrated into a plant-wide automation network.

The input arrangement is AC Input with Precharge and no DC terminals. The drive is configured as a filtered unit with the CM jumper installed, which is the preferred configuration for this J-series model.

The combination of high current capability, 600 V operation, Frame 8 construction, local operator interface, forced-air cooling, and embedded EtherNet/IP makes this drive particularly suitable for large conveyors, pumps, fans, blowers, crushers, mining equipment, cement and aggregate machinery, and other large industrial processes.

The dimensions and weight above are appropriate for preliminary engineering and equipment planning. The exact mechanical arrangement should always be checked against the applicable dimensional drawing when designing an enclosure, MCC lineup, lifting system, or installation area.

At approximately 634 kg, this is a large industrial drive and should be treated accordingly during transportation, lifting, installation, and maintenance planning.

4. Electrical Rating

The 20G1ABE355JN2NNNNN has a 355 A output-current rating.

This places the model within the higher-power section of the PowerFlex 755 family.

The principal duty ratings are:

Duty Classification	Motor Rating
Light Duty	400 HP
Normal Duty	350 HP
Heavy Duty	300 HP

The corresponding approximate metric power values are:

Duty Classification	HP	Approx. kW
Light Duty	400 HP	~298 kW
Normal Duty	350 HP	~261 kW
Heavy Duty	300 HP	~224 kW

These ratings should not be interpreted as three independent power capacities that can all be used simultaneously.

The actual usable rating depends on the application duty, overload requirements, ambient temperature, motor characteristics, operating frequency, acceleration requirements, and other installation conditions.

For this reason, the motor’s full-load current and actual mechanical load profile should normally be given priority over horsepower when selecting the drive.

5. Light Duty, Normal Duty and Heavy Duty

The duty classification is important for understanding the practical application range of this drive.

Light Duty

The Light Duty rating reaches approximately 400 HP.

This rating is suited to applications where the motor generally operates under relatively stable loading and does not require the same overload capability as a heavy-duty application.

Typical examples include large fans and certain pump applications.

Normal Duty

The Normal Duty rating is approximately 350 HP.

This is a useful reference point for general industrial motor applications where the mechanical load varies during operation but does not require the highest overload capability.

Heavy Duty

The Heavy Duty rating is approximately 300 HP.

This rating is more appropriate for demanding mechanical applications where starting torque, acceleration torque, load changes, or repeated overload conditions are significant.

Examples can include conveyors, crushers, mixers, material-handling systems, and certain mining applications.

6. 600 VAC Three-Phase Architecture

The 20G1ABE355JN2NNNNN is designed for a 600 VAC, three-phase input system.

This voltage class is commonly associated with larger industrial electrical installations.

At high motor power levels, using a higher system voltage helps keep current at a manageable level while delivering substantial motor power.

For a complete installation, the drive should be considered together with:

• Incoming power distribution
• Transformer capacity
• Branch protection
• Short-circuit requirements
• Motor cable selection
• Motor insulation
• Grounding
• EMC considerations
• Cabinet ventilation
• Ambient temperature
• Motor duty cycle
• Overload requirements

A properly sized drive is therefore determined by the complete electrical and mechanical system, not simply the nominal motor horsepower.

7. Frame 8 Design

The Frame 8 designation is an important characteristic of the 20G1ABE355JN2NNNNN.

Frame 8 is intended for large power applications and provides the physical space necessary for high-current power components and their associated cooling and control systems.

The approximate dimensions are:

2100 mm × 610 mm × 600 mm

The 600 mm depth corresponds to the MCC-style configuration.

This is considerably larger than compact VFD products used in small machines.

For installation planning, engineers should allow space for:

• Power cables
• Motor cables
• Grounding conductors
• Control wiring
• Network wiring
• Ventilation
• Maintenance access
• Lifting equipment
• Door or enclosure clearance
• Heat dissipation

The drive should be installed in an environment where the cooling airflow is not restricted.

8. Forced-Air Cooling

The drive uses a forced-air cooling system.

The cooling fan is specified as a backward-curved centrifugal fan.

The approximate fan airflow is 1805 m³/h, with an electrical input of approximately 0.45 kW.

The fan efficiency is approximately 63.7%.

The purpose of this cooling system is to remove heat generated by the drive’s high-power semiconductor devices, DC bus components, and associated power electronics.

At this power level, proper thermal management is essential.

A drive may have sufficient electrical capacity on paper but still experience reliability problems if the surrounding cabinet cannot remove the heat generated during continuous operation.

For this reason, the drive room or enclosure should provide suitable airflow and should prevent hot exhaust air from being drawn directly back into the cooling intake.

9. Enhanced LCD Full Numeric Handheld / Local HIM

The JN2 configuration is one of the defining characteristics of this model.

The 20G1ABE355JN2NNNNN includes an Enhanced LCD, Full Numeric, Handheld/Local HIM.

This provides a local interface for drive setup, operation, monitoring, and maintenance.

A local HIM can be useful when technicians need to work directly with the drive without depending entirely on a remote PLC or HMI.

Typical tasks may include:

• Viewing drive status
• Checking fault conditions
• Reviewing parameters
• Adjusting drive settings
• Checking operating values
• Performing commissioning
• Monitoring motor operation
• Troubleshooting abnormal conditions

This makes the JN2 version especially useful for installations where both centralized automation and local maintenance access are required.

10. JN0 vs JN2 vs JN4

The three configurations are particularly useful when selecting the appropriate PowerFlex 755 operator-interface arrangement.

Configuration	Operator Interface	Typical Application
JN0	No HIM / Blank	Centralized PLC or HMI control
JN2	Enhanced LCD, Handheld / Local HIM	Local maintenance and commissioning
JN4	Enhanced LCD, Door-Mounted HIM	Direct cabinet-door operation

The 20G1ABE355JN2NNNNN sits between the no-HIM and door-mounted versions in terms of local operator accessibility.

It is a practical choice when local personnel need access to the drive but the installation does not require a permanently mounted display on the cabinet door.

11. Embedded EtherNet/IP

The drive includes embedded EtherNet/IP.

This allows the PowerFlex 755 to function as an integrated component of a networked industrial control system.

For example, a large production system may use a PLC to coordinate several PowerFlex drives.

The PLC can issue commands while the drive reports information such as operating status, motor speed, current, warnings, and faults.

This provides a much more integrated architecture than a drive controlled entirely through hardwired start/stop signals.

Typical network-related information may include:

• Start command
• Stop command
• Speed reference
• Actual speed
• Drive status
• Output current
• Fault information
• Warning information
• Diagnostic information
• Parameter information

For large facilities, this can reduce wiring complexity and improve access to operating information.

12. AC Input with Precharge

The drive uses an AC input with precharge and does not include DC input terminals in this configuration.

The precharge function is important in high-power drives because the DC-link capacitors require controlled charging when the drive is energized.

Without suitable current control during the initial charging sequence, the inrush current could be extremely high.

The precharge architecture provides a controlled energization process and forms an important part of the drive’s high-power electrical design.

13. Filtered Configuration

The 20G1ABE355JN2NNNNN is specified with Filtered, CM Jumper Installed.

This is the preferred configuration for the J-series model.

The filtering arrangement is useful in applications where electromagnetic compatibility must be considered as part of the overall electrical design.

This can be particularly important in plants where high-power drives operate near:

• PLC systems
• Industrial Ethernet networks
• Instrumentation
• Sensors
• Communication equipment
• Control electronics
• Measurement systems

The drive should still be installed according to appropriate grounding, cable-routing, shielding, and EMC practices.

14. Product Applications

Large Conveyors

The 20G1ABE355JN2NNNNN is well suited to large conveyor systems.

A large conveyor can have substantial mechanical inertia, particularly when carrying heavy bulk materials.

Typical applications include:

• Industrial ventilation
• Dust collection
• Combustion air
• Process exhaust
• Furnace ventilation
• Large HVAC systems
• Mining ventilation

Cement and Aggregate

Cement and aggregate facilities commonly contain many large rotating machines.

The drive can be applied to:

Examples include:

• Large mixers
• Industrial processing machinery
• Material-processing systems
• Process pumps
• Large fans
• Blowers
• Material-handling equipment

15. Main Product Advantages

• Maintenance
• Troubleshooting
• Parameter adjustment
• Local inspection

This can reduce dependence on a remote control system during service work.

Embedded EtherNet/IP

Embedded EtherNet/IP makes the drive suitable for centralized automation.

The drive can exchange operating information with the control system and become part of the overall plant automation network.

Frame 8 Construction

The large Frame 8 platform is designed for high-power applications.

It provides the physical and thermal architecture required for large industrial motor-control systems.

Forced-Air Cooling

The forced-air system provides a practical cooling method for this power class.

It is well suited to properly ventilated industrial electrical rooms and MCC installations.

EMC Filtering

The filtered configuration helps support electromagnetic compatibility within the overall electrical installation.

Flexible Duty Ratings

The 400 HP LD / 350 HP ND / 300 HP HD structure gives users flexibility when application loading changes.

This is particularly useful when comparing motors that have similar horsepower but significantly different mechanical load profiles.

17. Five Recommended Models from the Same Series or Related Range

The following five models are closely related to the 20G1ABE355JN2NNNNN.

Model	Voltage	Output Current	LD	ND	HD	HIM	Frame	Cooling
20G1ABE355JN0NNNNN	600 VAC, 3PH	355 A	400 HP	350 HP	300 HP	No HIM	8	Air Cooled
20G1ABE355JN4NNNNN	600 VAC, 3PH	355 A	400 HP	350 HP	300 HP	Door-Mounted LCD	8	Air Cooled
20G1ABE395JN2NNNNN	600 VAC, 3PH	395 A	450 HP	400 HP	350 HP	Handheld / Local LCD	8	Air Cooled
20G1ABE435JN2NNNNN	600 VAC, 3PH	435 A	500 HP	450 HP	350 HP	Handheld / Local LCD	8	Air Cooled
20G1ABE460JN2NNNNN	600 VAC, 3PH	460 A	500 HP	450 HP	400 HP	Handheld / Local LCD	8	Air Cooled

The first two alternatives maintain the same 355 A electrical class while changing the operator-interface configuration.

The 395 A, 435 A, and 460 A versions provide additional current capacity and therefore become useful when the motor load is close to the upper capability of the 355 A model.

18. Detailed Comparison of Related Models

Model	Current	LD Rating	ND Rating	HD Rating	Approx. Dimensions	Approx. Weight
20G1ABE355JN0NNNNN	355 A	400 HP	350 HP	300 HP	~2100 × 610 × 600 mm	~634 kg
20G1ABE355JN2NNNNN	355 A	400 HP	350 HP	300 HP	~2100 × 610 × 600 mm	~634 kg
20G1ABE355JN4NNNNN	355 A	400 HP	350 HP	300 HP	~2100 × 610 × 600 mm	~634 kg
20G1ABE395JN2NNNNN	395 A	450 HP	400 HP	350 HP	~2100 × 610 × 600 mm	~634 kg

20G1ABE460JN2NNNNN	460 A	500 HP	450 HP	400 HP	~2100 × 610 × 600 mm	~634 kg

The weight and dimensional values are approximate because exact mechanical configuration, accessories, packaging, and installation arrangement can affect the final equipment size and weight.

For detailed cabinet fabrication, the exact dimensional drawing should be used.

19. Five Popular Allen-Bradley Models

20G1ABC650JN4NNNNN	PowerFlex 755	480 VAC Class	~650 A	Very large industrial	Large Frame	Large MCC style	~600+ kg class

The comparison illustrates the broad range of drive sizes available under the same brand.

For a 350 HP-class 600 V motor, the 20G1ABE355JN2NNNNN is much more relevant than the compact PowerFlex 523 or PowerFlex 525 models.

21. Local HIM Advantages

The local HIM is one of the strongest reasons to select the JN2 configuration instead of JN0.

A no-HIM drive is excellent when the system is entirely centralized.

However, maintenance personnel often benefit from being able to interact with the drive directly.

The local HIM can make commissioning more convenient because technicians can inspect parameters and operating conditions at the drive itself.

During troubleshooting, this can reduce the amount of time required to determine whether a problem originates from the motor, drive, control system, communication network, or process equipment.

The JN2 configuration is therefore particularly attractive for plants where both remote automation and local maintenance access are important.

22. Advantages for Maintenance

High-power industrial drives are often installed in locations where downtime can be expensive.

The local HIM gives maintenance personnel direct access to the drive.

This can simplify tasks such as:

• Checking operating conditions
• Confirming parameters
• Investigating faults
• Checking drive status
• Performing commissioning
• Reviewing diagnostic information
• Verifying control settings

The benefit becomes especially noticeable in large plants containing multiple drives.

23. Advantages for Centralized Automation

Although the JN2 includes a local interface, it does not prevent the drive from being used in a centralized automation architecture.

The drive can simultaneously provide local access and communicate through EtherNet/IP.

This gives the installation two levels of interaction:

Local level: technician or operator interacts with the HIM.

System level: PLC or control system communicates with the drive through the industrial network.

This combination provides greater flexibility than a drive designed only for local operation or only for remote control.

25. Application Selection Guide

Application	Suitability	Main Consideration
Large Conveyor	Excellent	Starting torque and load inertia
Mining Conveyor	Excellent	Continuous heavy industrial operation
Crusher	Excellent	High mechanical loading
Large Pump	Excellent	Variable-speed process control
Large Fan	Excellent	Long-duration operation
Blower	Excellent	Airflow regulation
Cement Machinery	Excellent	Large motors and centralized control
Aggregate Equipment	Excellent	Crushers and conveyors
Material Handling	Excellent	High motor power
Process Machinery	Excellent	Networked control
Water Pumping	Very Good	Large pumping systems
Industrial Ventilation	Very Good	Large fan systems

26. Important Installation Considerations

Because the 20G1ABE355JN2NNN is a large Frame 8 drive, installation should be treated as an engineering project rather than a simple equipment-mounting operation.

The approximate physical size is:

2100 mm H × 610 mm W × 600 mm D

The approximate weight is:

634 kg

Adequate floor loading should therefore be confirmed before installation.

The access route should also be checked.

Door widths, elevators, loading areas, crane capacity, lifting equipment, and final positioning all need to accommodate a drive of this size and weight.

The cooling airflow should also be considered.

A large drive can generate considerable heat during operation, and insufficient ventilation can shorten component life or cause thermal protection trips.

27. Why This Model Is Suitable for Large Industrial Systems

The 20G1ABE355JN2NNNNN combines several features that are particularly valuable in large industrial systems.

First, it provides substantial current capacity.

Second, it operates in the 600 V class.

Third, it uses a large Frame 8 architecture.

Fourth, it includes embedded EtherNet/IP.

Fifth, it provides a local enhanced LCD HIM.

Sixth, it uses forced-air cooling.

Seventh, it supports multiple duty classifications.

This combination makes it much more than a basic frequency converter.

It can function as an important control component in a large automated production system.

28. Overall Advantages Summary

29. Final Technical Summary

The Allen-Bradley 20G1ABE355JN2NNNNN is a high-power PowerFlex 755 AC Drive belonging to the PowerFlex 750-Series.

Its principal electrical configuration is 600 VAC, three-phase, 355 A, with approximately 400 HP Light Duty, 350 HP Normal Duty, and 300 HP Heavy Duty ratings.

The drive uses a Frame 8 power structure with a Type 1 / IP20, 600 mm deep MCC-style enclosure.

It is forced-air cooled, uses AC input with precharge, has no DC terminals, includes filtered EMC configuration, and has the CM jumper installed.

The defining feature of the JN2 configuration is the Enhanced LCD Full Numeric Handheld/Local HIM.

This local interface makes the model particularly useful in industrial environments where technicians need direct access to the drive during commissioning, maintenance, troubleshooting, and parameter adjustment.

At the same time, embedded EtherNet/IP allows the drive to participate in a centralized automation system.

The drive is therefore capable of supporting both local and remote interaction.

Its strongest application areas include large conveyors, mining machinery, crushers, large pumps, fans, blowers, cement plants, aggregate processing equipment, material-handling systems, and large process machinery.

The approximate physical dimensions are 2100 × 610 × 600 mm, and the approximate weight is 634 kg.

Because of its size and weight, the drive should be installed in a properly engineered industrial electrical environment with adequate floor loading, mechanical handling capability, ventilation, maintenance clearance, and cable-access provisions.

For projects where the same 355 A / 600 V power class is required but a different operator-interface arrangement is preferred, the 20G1ABE355JN0NNNNN and 20G1ABE355JN4NNNNN are the most directly related alternatives.

The JN0 version is intended for applications that do not require a local HIM.

The JN4 version is intended for applications requiring a door-mounted operator interface.

For applications requiring additional current margin, the 395 A, 435 A, and 460 A versions provide progressively larger drive capacity.

Overall, the 20G1ABE355JN2NNNNN is a strong choice for large industrial motor applications where high power, 600 V operation, local operator access, EtherNet/IP communication, flexible duty ratings, Frame 8 construction, and centralized industrial automation are all important considerations.
