---

3. Detailed Electrical Parameters

The 20G1AJE395AN0NNNNN is intended for 600 VAC three-phase systems.

Its three duty classifications are particularly important because the usable motor horsepower depends on the type of load.

Electrical Parameter	Specification
Catalog Number	20G1AJE395AN0NNNNN
Input Voltage	600 VAC class
Input Phase	3 Phase
Light-Duty Continuous Current	395 A
Light-Duty 1-Minute Current	Approx. 435 A
Light-Duty Motor Rating	450 HP
Normal-Duty Continuous Current	355 A
Normal-Duty 1-Minute Current	Approx. 391 A
Normal-Duty 3-Second Current	Approx. 533 A
Normal-Duty Motor Rating	400 HP
Heavy-Duty Continuous Current	Approx. 295 A
Heavy-Duty 1-Minute Current	Approx. 443 A
Heavy-Duty 3-Second Current	Approx. 533 A
Heavy-Duty Motor Rating	350 HP
Approximate Metric Power Class	300 kW class
DC Bus Class	Approximately 810 VDC
Input Type	AC Input with Precharge
DC Input Terminals	None
Cooling	Forced Air
Filtering	Filtered
CM Jumper	Removed
Dynamic Braking	None
Internal Braking Transistor	None

The published selection data gives the 395 A drive a 450 HP light-duty rating, 400 HP normal-duty rating, and 350 HP heavy-duty rating.

For normal industrial applications, the 400 HP normal-duty rating is often the most useful reference point.

For equipment with frequent overloads, high acceleration torque, or difficult mechanical starting conditions, the heavy-duty rating should be considered rather than selecting the drive solely from the motor horsepower nameplate.

---

4. Understanding the Duty Ratings

The three duty classifications allow the same drive platform to be applied to different mechanical load profiles.

Light Duty

The light-duty rating provides the highest horsepower capability.

It is generally appropriate for applications where the load profile is relatively moderate and the motor does not experience severe overload conditions.

The 20G1AJE395AN0NNNNN provides approximately 450 HP in this classification.

Typical examples include certain large fan, blower, and pump applications.

Normal Duty

The normal-duty rating provides approximately 400 HP.

This is a useful rating for many general industrial applications where the motor experiences normal acceleration and operating conditions without prolonged severe overload.

Heavy Duty

The heavy-duty rating is approximately 350 HP.

The reduction in horsepower compared with light duty reflects the greater thermal and current demands associated with more demanding load conditions.

This rating is more relevant to equipment such as heavily loaded conveyors, certain material-handling systems, crushers, and other machinery requiring higher torque or frequent overload capability.

---

5. Product Series – PowerFlex 755

The PowerFlex 755 series is designed for high-performance industrial motor-control applications.

It is particularly suitable for larger motors and machinery where drive communication, diagnostics, network integration, and advanced control functions are important.

The 20G1AJE395AN0NNNNN represents one of the high-power 600 VAC configurations within the series.

The large Frame 8 mechanical design allows the drive to accommodate substantially higher motor power than compact drive families.

This makes the product suitable for plant-level equipment rather than only individual small machines.

---

6. Catalog Number Configuration

The catalog number 20G1AJE395AN0NNNNN identifies a very specific combination of electrical and mechanical features.

The 20G1 prefix identifies the PowerFlex 755 platform.

The AJE section identifies the 600 VAC class configuration.

The 395 section identifies the 395 A light-duty current class.

The AN0 configuration is also significant.

The A configuration corresponds to the specified CM jumper arrangement, while the N0 configuration identifies the blank/no-HIM version.

Therefore, this product should not be treated as interchangeable with every other 395 A PowerFlex 755 drive simply because the current rating is identical.

The operator-interface arrangement, CM-jumper configuration, enclosure, input architecture, braking configuration, and mechanical package should all be checked during replacement.

---

7. HIM Configuration – Blank / No HIM

Unlike the AN4 version, the 20G1AJE395AN0NNNNN is supplied in a blank / no-HIM configuration.

This means the drive does not include the enhanced full numeric HIM as part of this catalog configuration.

This arrangement can be useful when the drive is intended to be integrated into a centralized control system and local operator-interface functions are not required on every individual drive.

It can also be advantageous where the operator interface is provided elsewhere in the control architecture.

Typical examples include a plant PLC/HMI system, a centralized operator station, or a control room where individual local keypads are not required.

For maintenance purposes, technicians may use the appropriate external interface or temporary HIM arrangement when required.

---

8. Enclosure and Protection

The drive uses an IP54 / NEMA Type 12 enclosure configuration.

This is an important characteristic for industrial installations because the enclosure provides protection against dust, dirt, and other typical indoor industrial contaminants.

The product is not intended to be treated as a small open-frame inverter.

The 800 mm deep MCC-style package is designed for integration into large industrial electrical systems.

Mechanical Parameter	Specification
Catalog Number	20G1AJE395AN0NNNNN
Frame	Frame 8
Enclosure	NEMA Type 12
Protection	IP54
Package Style	800 mm Deep MCC Style
Cooling	Air Cooled
Approx. Height	2100–2500 mm
Approx. Width	600 mm
Approx. Depth	800 mm
Approx. Weight	600–650 kg
Installation	Industrial / MCC / Floor-mounted System
Service Access	Front Service Area Recommended
Ventilation	Forced-Air Cooling Required

The dimensions and weight shown above should be treated as engineering planning values.

For fabrication of a cabinet, MCC section, foundation, transportation frame, lifting system, or maintenance enclosure, the exact mechanical drawing for the selected configuration should always be used.

---

9. Dimensions and Weight

The 20G1AJE395AN0NNNNN is a large Frame 8 drive.

A practical preliminary planning envelope is approximately:

2100–2500 mm height × 600 mm width × 800 mm depth

The approximate equipment weight can be considered in the range of:

600–650 kg

The actual installation weight can vary depending on the exact packaging, configuration, accessories, mounting arrangement, and shipping configuration.

For that reason, the approximate weight should be used for early engineering, transportation planning, and space allocation rather than as a certified lifting value.

Physical Parameter	Approximate Value
Model	20G1AJE395AN0NNNNN
Height	2100–2500 mm
Width	600 mm
Depth	800 mm
Approx. Weight	600–650 kg
Frame	8
Enclosure	NEMA Type 12
IP Rating	IP54
Package	800 mm Deep MCC Style

Because the equipment is approximately several hundred kilograms, installation planning should also consider lifting access, floor loading, transportation routes, service clearance, and cabinet access.

---

10. AC Input with Precharge

The drive uses an AC input with precharge.

The catalog configuration does not provide DC input terminals.

The precharge function is part of the input architecture and helps manage initial charging of the drive’s DC bus.

This is important when integrating the drive into a plant power system.

It also means that the drive should not automatically be assumed to support every common-DC-bus configuration simply because it belongs to the PowerFlex 755 family.

The exact input and DC-bus architecture should always be checked when replacing a drive or integrating it into an existing system.

---

11. Filtering and CM Jumper

The 20G1AJE395AN0NNNNN is supplied with a filtered configuration and the CM jumper removed.

These details can be important in industrial applications involving long motor cables, sensitive instrumentation, communication networks, and multiple drives installed in the same electrical area.

The CM-jumper configuration influences the common-mode electrical characteristics of the installation.

Proper grounding and cable installation remain essential.

Configuration	20G1AJE395AN0NNNNN
Model	20G1AJE395AN0NNNNN
EMC Filtering	Filtered
CM Jumper	Removed
Dynamic Braking	None
Internal Braking Transistor	None
AC Precharge	Yes
DC Terminals	None
Cooling	Air Cooled

---

12. EtherNet/IP Communication

The 20G1AJE395AN0NNNNN includes embedded EtherNet/IP functionality.

This provides an important advantage in modern industrial automation systems.

The drive can be integrated into an automation network rather than operating as a completely independent motor controller.

Depending on the control architecture, the automation system can exchange information such as:

• Start command
• Stop command
• Speed reference
• Frequency reference
• Drive status
• Motor current
• Output frequency
• Fault status
• Warning status
• Operating condition
• Diagnostic information

This architecture can significantly simplify the control of large numbers of drives in a production facility.

---

13. Application Areas

The 20G1AJE395AN0NNNNN is primarily suited to large industrial motor applications.

Its 600 VAC class input, 395 A light-duty current capability, 400 HP normal-duty rating, and Frame 8 construction make it particularly appropriate for large mechanical systems.

13.1 Large Pumps

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

Industrial water systems, process pumps, cooling-water pumps, raw-water systems, and transfer pumps often require variable-speed operation.

The drive can adjust motor speed according to process demand.

This can provide better flow and pressure control compared with fixed-speed motor operation.

Typical applications include:

• Water transfer pumps
• Process-water pumps
• Cooling-water pumps
• Industrial circulation pumps
• Raw-water pumps
• Wastewater pumps
• Large irrigation pumps

---

14. Fan and Blower Applications

Large fans and blowers frequently use motors in the hundreds of horsepower.

Variable-speed control allows airflow to be adjusted according to process requirements.

Typical applications include:

• Industrial ventilation
• Furnace fans
• Exhaust systems
• Induced-draft fans
• Forced-draft fans
• Process blowers
• Dust collection systems
• Large HVAC-related industrial systems

The drive’s large current capacity makes it suitable for fan systems that exceed the practical range of smaller variable-frequency drives.

---

15. Conveyor Systems

Large conveyors can impose significant mechanical loads during acceleration.

A high-power AC drive can provide controlled acceleration and deceleration rather than relying on direct-on-line starting.

This can reduce mechanical shock and help coordinate motor speed with the overall material-handling system.

Potential applications include:

• Mining conveyors
• Cement conveyors
• Aggregate conveyors
• Port material handling
• Bulk material handling
• Heavy industrial transfer systems
• Warehouse material systems

---

16. Mining Applications

Mining operations frequently use high-power motors for conveyors, pumps, ventilation systems, crushers, and material-processing machinery.

The 20G1AJE395AN0NNNNN can be considered for these applications when the electrical environment and motor duty are appropriate.

The large Frame 8 configuration provides a substantial platform for high-power motor control.

The integrated network capability also makes it suitable for centralized control architectures.

---

17. Cement and Aggregate Equipment

Cement and aggregate facilities use large motors throughout the production process.

Typical applications include:

• Material conveyors
• Large fans
• Crushers
• Pumps
• Blowers
• Material feeders
• Processing machinery

The 400 HP normal-duty class makes the drive suitable for many large motor applications within this sector.

For crushers and other severe-load machinery, the heavy-duty current requirement should be evaluated carefully.

---

18. Water and Wastewater Applications

Large municipal and industrial water systems often use high-power motors continuously.

The drive can be applied to:

• Raw-water pumping
• Wastewater pumping
• Sludge systems
• Aeration blowers
• Filtration systems
• Process-water circulation
• Cooling-water systems

Variable-speed operation can allow the process system to respond to changing demand rather than continuously running the motor at maximum speed.

---

19. Compressor Applications

Industrial compressors can also benefit from variable-speed motor control.

A PowerFlex 755 drive can provide controlled motor speed while exchanging process information with the plant automation system.

Before applying the drive to a compressor, the engineering team should verify the compressor manufacturer’s motor requirements, starting torque, overload profile, speed range, and cooling requirements.

---

20. Heavy Industrial Machinery

The drive can also be used in other high-power machinery where variable-speed motor control is required.

Potential applications include:

• Large process machines
• Material-handling equipment
• Production-line machinery
• Industrial ventilation systems
• Large mixers
• Processing equipment
• Utility machinery
• Manufacturing plant equipment

The exact suitability depends on motor current, load profile, speed range, acceleration requirements, and environmental conditions.

---

21. Main Product Advantages

21.1 High Current Capability

The primary advantage of the 20G1AJE395AN0NNNNN is its high output-current capability.

With a 395 A light-duty rating and 355 A normal-duty rating, it is designed for large motors.

This places it well above compact machine-level drives.

---

21.2 400 HP Normal-Duty Capability

A normal-duty rating of approximately 400 HP makes this model appropriate for large industrial motors.

This allows the drive to be used in applications where smaller PowerFlex models would not provide sufficient capacity.

---

21.3 600 VAC Three-Phase Platform

The 600 VAC class makes the drive suitable for high-voltage industrial motor systems.

This is particularly useful in facilities where large motors operate on higher-voltage three-phase power systems.

---

21.4 Large Frame 8 Construction

Frame 8 provides a robust platform for high-power applications.

The large-frame construction allows the electrical system, cooling system, and power components to be packaged for industrial service.

---

21.5 Industrial Enclosure

The IP54 / NEMA Type 12 configuration is useful for industrial indoor environments.

It provides considerably more enclosure protection than a basic open-frame configuration.

---

21.6 Integrated EtherNet/IP

Embedded EtherNet/IP makes the drive suitable for modern PLC-based automation systems.

This allows drive operation to become part of a larger control strategy.

---

21.7 No-HIM Configuration

The blank/no-HIM configuration is useful for installations where local keypad operation is not required.

It can reduce unnecessary local operator-interface hardware when the entire drive system is controlled through a plant HMI or control-room system.

---

21.8 Filtered Configuration

The integrated filtering configuration supports the electrical design of industrial installations where EMC considerations are important.

It is especially relevant in facilities containing multiple drives, PLCs, instrumentation, and communication networks.

---

21.9 Flexible Duty Selection

The light-duty, normal-duty, and heavy-duty ratings allow the same basic drive platform to be evaluated against different load characteristics.

This is useful when selecting equipment for pumps, fans, conveyors, and other machinery with different overload profiles.

---

23. Installation Considerations

The 20G1AJE395AN0NNNNN is not a small wall-mounted drive.

Its large physical size and approximately several-hundred-kilogram weight require careful installation planning.

The electrical room or MCC location should provide sufficient space for:

• Drive installation
• Power cable routing
• Motor cable routing
• Grounding connections
• Cooling airflow
• Maintenance access
• Component replacement
• Inspection
• Lifting and transportation

The ventilation system must also be considered.

Because this is an air-cooled high-power drive, the ambient temperature and airflow conditions can have a direct effect on drive thermal performance.

---

24. Motor Selection Considerations

The motor should be selected based on current as well as horsepower.

Important parameters include:

• Motor rated voltage
• Motor rated current
• Motor horsepower
• Motor frequency
• Motor speed
• Motor overload
• Starting torque
• Load torque
• Acceleration time
• Deceleration time
• Motor cable length
• Motor insulation system
• Environmental conditions

A 400 HP motor is not automatically compatible simply because the drive carries a 400 HP normal-duty rating.

The actual motor full-load current must be compared with the applicable drive current rating.

The mechanical load profile must also be evaluated.

---

25. Maintenance Considerations

The drive should be included in a planned preventive-maintenance program.

Recommended maintenance areas include:

• Cooling fans
• Airflow paths
• Electrical terminals
• Grounding connections
• Power cables
• Motor cables
• Enclosure condition
• Internal contamination
• Drive temperature
• Fault history
• Alarm history
• Communication status
• Mechanical mounting
• Ventilation conditions

Because the drive is used for large motors, a drive failure can potentially stop a major production process.

Preventive maintenance is therefore particularly valuable.

---

The replacement should be evaluated carefully rather than assumed to be a physically and electrically identical drop-in unit.

In particular, engineers should compare:

• Current rating
• Motor horsepower
• Input voltage
• Enclosure
• Frame
• HIM configuration
• CM jumper configuration
• Filtering
• Braking
• Communication
• Dimensions
• Cooling
• Cable connections

---

35. Overall Product Evaluation

The Allen-Bradley 20G1AJE395AN0NNNNN is a high-power industrial AC drive designed for large three-phase motors operating in a 600 VAC class system.

Its 395 A light-duty rating, 355 A normal-duty rating, and 295 A heavy-duty rating provide flexibility across different mechanical load profiles.

The approximately 450 HP light-duty, 400 HP normal-duty, and 350 HP heavy-duty motor ratings make this drive suitable for substantial industrial equipment.

The Frame 8, IP54 / NEMA Type 12, and 800 mm deep MCC-style construction place it firmly in the large industrial drive category.

Its embedded EtherNet/IP capability makes it suitable for integration into modern automation systems.
