Allen-Bradley 20G1G3E395LNDNNNNN PowerFlex 755 AC Drive

1. Product Overview

The Allen-Bradley 20G1G3E395LNDNNNNN is a high-power AC variable frequency drive from the PowerFlex 755 series.

It is designed for large industrial motor-control applications where high current capacity, variable-speed operation, controlled acceleration, process flexibility, and integration with an industrial automation system are required.

The model belongs to the 600 VAC three-phase class and is identified as a 395 A class PowerFlex 755 configuration.

It is an air-cooled, high-power packaged drive intended for substantial industrial motor systems.

Compared with compact variable frequency drives, this model is designed for significantly larger motors and heavier industrial equipment.

Typical applications include large pumps, fans, blowers, conveyors, compressors, mixers, agitators, material-handling systems, process equipment, cooling systems, and other high-power rotating machinery.

The E395 configuration sits above the E355 model in the same general 600 VAC PowerFlex 755 range.

It therefore provides additional current and motor capacity while remaining within the large high-power drive category.

Because of its high-power construction, installation involves more than simply connecting the drive to a motor.

Electrical distribution, cabinet arrangement, thermal management, cable routing, grounding, mechanical support, maintenance clearance, and equipment handling all need to be considered during system design.

---

4. Electrical Specifications

The 20G1G3E395LNDNNNNN is designed for 600 VAC three-phase industrial motor systems.

This makes it appropriate for large motors commonly used in industrial plants and heavy-duty process equipment.

Electrical Parameter	Specification
Model	20G1G3E395LNDNNNNN
Input Voltage Class	600 VAC
Input Phase	Three-phase
Current Class	395 A
Normal Duty	Approximately 400 hp
Light Duty	Approximately 450 hp

Frame	8

A 600 VAC motor system is commonly associated with higher-power industrial equipment.

Higher operating voltage can help reduce current for a given motor power compared with lower-voltage systems.

This can influence conductor selection and the design of the upstream electrical distribution system.

The drive should always be matched to the actual motor voltage and nameplate current.

---

5. Motor Capacity and Duty Ratings

One of the most important considerations when selecting the E395 is the difference between Light Duty, Normal Duty and Heavy Duty operation.

Duty Rating	Approximate Motor Capacity	Typical Load Characteristic
Light Duty	450 hp class	Variable torque
Normal Duty	400 hp class	General industrial loads
Heavy Duty	350 hp class	High torque / constant torque

A centrifugal fan and a heavy-duty conveyor can both use a large motor, but their torque requirements are different.

A fan normally has a variable-torque characteristic.

A heavily loaded conveyor may require considerably more torque during acceleration.

A mixer may also experience significant torque changes depending on the material being processed.

For this reason, selecting the E395 solely from the motor horsepower is not recommended.

Motor current and load profile are more important for final drive sizing.

---

6. Physical Dimensions and Weight

The E395 configuration uses the large Frame 8 platform.

This makes it significantly larger than the Frame 7 E295 configuration.

Physical Parameter	Specification
Model	20G1G3E395LNDNNNNN
Frame	8
Height	2453 mm
Width	600 mm
Depth	600 or 800 mm
Approx. Basic Weight	623 kg
Approx. Height	96.6 in
Approx. Width	23.6 in
Approx. Depth	23.6 or 31.5 in
Approx. Weight	1374 lb
Cooling	Forced air
Installation	Cabinet / industrial lineup
Enclosure	Open-type / cabinet configuration

The approximately 623 kg basic weight is an important mechanical consideration.

The equipment should be transported and installed using suitable industrial handling equipment.

The floor or mounting structure should also be evaluated for the weight of the complete assembly.

The actual installation footprint can be larger than the drive dimensions because additional room is required for cable routing, ventilation and maintenance access.

---

7. Frame 8 Mechanical Characteristics

The Frame 8 platform is designed for large industrial drive systems.

It provides the physical space required for high-power electrical components, cooling equipment, power connections and control hardware.

---

8. Product Introduction

The PowerFlex 755 series is designed for applications where motor control is a major part of the industrial process.

The drive does not simply provide a variable output frequency.

It can become part of the overall control architecture of a machine or process.

A large water pump, for example, may need to operate at several different speeds depending on flow requirements.

A large fan may need to change speed according to ventilation demand.

A conveyor may require smooth acceleration to reduce mechanical stress.

A mixer may operate at different speeds during different production stages.

A compressor may need to adjust its speed according to changing process conditions.

The E395 provides the current capacity required for many of these large industrial applications.

Its 600 VAC class is also appropriate for high-power motor systems.

---

9. Large Pump Applications

Large pumps are an important application area for the E395.

Industrial pumping systems frequently operate under changing process conditions.

A fixed-speed motor may run continuously at full speed even when the process does not require maximum flow.

Variable-speed operation allows the motor speed to be adjusted according to actual demand.

Typical applications include:

• Industrial water circulation.
• Cooling-water systems.
• Process-fluid circulation.
• Large water transfer systems.
• Utility pumping.
• Industrial treatment systems.
• Process pumps.

The drive can provide controlled acceleration and adjustable operating speed.

This can help make the overall pumping system easier to control.

---

10. Large Fan Applications

Large industrial fans can require hundreds of horsepower.

Examples include:

• Factory ventilation.
• Exhaust systems.
• Cooling towers.
• Process ventilation.
• Industrial air circulation.
• Large combustion-air systems.
• Dust collection systems.

The E395 provides enough capacity for substantial fan motors.

For variable-torque fan applications, the Light Duty rating can provide higher horsepower capacity than the Normal Duty rating.

This makes duty selection particularly important.

---

11. Blower Applications

Large blowers are another suitable application.

Blowers can be used in industrial ventilation, process-air systems and other applications requiring continuous air movement.

Variable-speed operation can allow the blower output to follow the process requirement.

This can provide greater flexibility than operating the blower at a single fixed speed.

---

12. Conveyor Applications

Large conveyors can require significant motor torque.

This is particularly true when the conveyor starts under load.

The E395 can provide controlled acceleration for large conveyor systems when the motor current and duty requirements are within its rating.

Controlled acceleration can reduce sudden mechanical loading on:

• Belts.
• Gearboxes.
• Couplings.
• Shafts.
• Bearings.
• Drive pulleys.

For conveyors with high starting torque or frequent acceleration cycles, the Heavy Duty rating should be evaluated carefully.

---

13. Compressor Applications

Large compressors can require substantial motor power and controlled operation.

The drive can provide adjustable motor speed for applications where compressor output needs to respond to changing process requirements.

Compressor torque characteristics vary by machine type.

Therefore, the final selection should be based on the actual compressor load curve and motor current.

---

14. Mixer Applications

Industrial mixers can have highly variable mechanical loads.

The motor may experience increased torque as material is introduced into the mixing vessel.

Different materials can also produce different torque requirements.

The E395 can be suitable for large mixer systems when properly sized.

Controlled acceleration can help reduce mechanical shock during startup.

---

15. Agitator Applications

Agitators can require continuous torque over long operating periods.

They may also need controlled speed adjustment to achieve the desired mixing performance.

The E395 can provide the required variable-speed control for large agitator systems when the motor current and duty cycle fall within the drive rating.

---

16. Material-Handling Applications

High-power material-handling equipment often requires precise control of acceleration and operating speed.

Examples include:

• Large conveyors.
• Bulk-material systems.
• Transfer equipment.
• Industrial feeders.
• Heavy-duty handling machinery.

Variable-speed control can help coordinate multiple machines in the same production process.

---

17. Process Machinery

The E395 can also be used in large process machines.

Examples include:

• Rotating production equipment.
• Large process pumps.
• Process blowers.
• Large mixers.
• Industrial agitators.
• High-power mechanical systems.

The drive can provide a controlled motor interface between the electrical supply and the mechanical process.

---

18. Main Product Advantages

18.1 High Current Capability

The approximately 395 A class provides substantial motor-control capacity.

This makes the E395 appropriate for large industrial motors that are outside the normal range of compact variable frequency drives.

---

18.2 600 VAC Industrial Operation

The 600 VAC class makes the model suitable for high-power motor systems.

This is especially useful in industrial facilities with higher-voltage motor distribution.

---

18.3 Approximately 400 hp Normal Duty

The approximately 400 hp Normal Duty rating gives the E395 a broad application range.

It can be used for many large pumps, conveyors, blowers and other industrial machines.

---

18.4 Approximately 450 hp Light Duty

Variable-torque applications can take advantage of the higher Light Duty rating.

Large centrifugal pumps and fans are typical examples where this distinction can be important.

---

18.5 Approximately 350 hp Heavy Duty

The Heavy Duty rating makes the E395 suitable for demanding applications where greater torque capability is required.

This is particularly relevant to conveyors, mixers and other constant-torque machines.

---

18.6 PowerFlex 755 Platform

The PowerFlex 755 platform is designed for large industrial automation systems.

It provides a flexible basis for motor control, process integration, feedback and communication functions.

---

18.7 Large Frame 8 Construction

The Frame 8 construction is designed for high-power installations.

It provides a cabinet-based architecture appropriate for centralized electrical rooms.

---

18.8 Variable-Speed Operation

The drive allows the motor to operate at different speeds according to process requirements.

This can provide greater flexibility than fixed-speed operation.

---

18.9 Controlled Acceleration

Large motors can produce substantial mechanical shock when started directly.

Controlled acceleration allows the machine to reach operating speed more gradually.

This can reduce stress on mechanical components.

---

18.10 Flexible Industrial Integration

The PowerFlex 755 architecture can be integrated into larger industrial control systems.

This makes the drive appropriate for automated production and process-control applications.

---

19. Energy Efficiency Considerations

Variable-speed operation can provide significant process benefits in suitable applications.

For pumps and fans, the required power can decrease substantially as motor speed is reduced.

This means that a drive can potentially reduce energy consumption when the process frequently operates below full capacity.

However, actual energy savings depend on the complete system.

Important factors include:

• Motor efficiency.
• Pump or fan efficiency.
• Operating speed.
• Load profile.
• Operating hours.
• Process requirements.
• Piping or duct system resistance.

The drive should therefore be considered as part of the complete energy-management strategy rather than as an isolated energy-saving device.

---

20. Thermal Management

The E395 is a high-power air-cooled drive.

Thermal management is therefore an important installation consideration.

The cooling airflow must remain unobstructed.

The surrounding electrical room must also have sufficient cooling capacity.

If several high-power drives operate in the same electrical room, the total heat load can become substantial.

The complete room should therefore be evaluated for:

• Ambient temperature.
• Ventilation.
• Heat rejection.
• Airflow.
• Equipment spacing.
• Dust and contamination.

Proper thermal management can contribute significantly to reliable long-term operation.

---

21. Installation Considerations

The large size and weight of the E395 require careful installation planning.

Important considerations include:

• Cabinet dimensions.
• Floor loading.
• Lifting equipment.
• Transportation route.
• Power cable routing.
• Motor cable routing.
• Control wiring.
• Communication wiring.
• Grounding.
• Ventilation.
• Service access.

The approximately 623 kg basic equipment weight means that suitable mechanical handling equipment should be available.

The cabinet should be installed on an appropriately designed supporting structure.

Adequate clearance should be provided around the equipment for inspection and maintenance.

---

22. Maintenance Considerations

High-power drives should be included in a planned preventive-maintenance program.

Cooling fans and ventilation passages should be inspected periodically.

The cabinet should be kept free from excessive dust and contamination.

Electrical connections should be inspected according to the applicable maintenance procedures.

The surrounding environment should remain within the permitted temperature and humidity range.

Because the equipment operates at high voltage and high current, appropriate electrical isolation and safety procedures are essential before maintenance work.

These models provide a useful progression around the E395 configuration.

The E242 and E295 models are lower-current alternatives.

The E355 provides slightly less capacity while remaining in the same general high-power family.

The E435 provides additional current and motor capacity above the E395.

---

25. Five Larger Related Models

For projects requiring more motor capacity than the E395, the following larger configurations can be considered.

Model	Series	Voltage	Current Class	Frame	Light Duty	Normal Duty	Heavy Duty	Approx. Dimensions	Approx. Weight
20G1G3E435LNDNNNNN	PowerFlex 755	600 VAC	435 A	8	500 hp class	450 hp class	400 hp class	2453 × 600 × 600/800 mm	~623 kg
20G1G3E545LNDNNNNN	PowerFlex 755	600 VAC	545 A	8	600 hp class	550 hp class	450 hp class	2453 × 600 × 600/800 mm	~623 kg
20G1G3E595LNDNNNNN	PowerFlex 755	600 VAC	595 A	9	700 hp class	600 hp class	550 hp class	2453 × 1200 × 600/800 mm	~1246 kg
20G1G3E690LNDNNNNN	PowerFlex 755	600 VAC	690 A	9	800 hp class	700 hp class	600 hp class	2453 × 1200 × 600/800 mm	~1246 kg
20G1G3E760LNDNNNNN	PowerFlex 755	600 VAC	760 A	9	900 hp class	800 hp class	700 hp class	2453 × 1200 × 600/800 mm	~1246 kg

The E435 and E545 remain in the Frame 8 range.

The E595 and higher configurations move into the larger Frame 9 platform.

This increase is significant from both electrical and mechanical perspectives.

The Frame 9 configurations can weigh approximately 1246 kg, which is roughly twice the basic weight of the Frame 8 configuration.

---

26. Five Representative Same-Brand Models

The following are representative models from other PowerFlex product families.

They cover smaller and medium-sized motor applications and should not be treated as direct replacements for the E395.

Model	Series	Voltage Class	Current Class	Approx. Power Range	Approx. Dimensions	Approx. Weight	Typical Application
25B-D010N114	PowerFlex 525	480 VAC	10 A class	Approx. 4–7.5 kW	Approx. 180 × 100 × 200 mm	~2–3 kg	Small pumps and fans
25B-D017N114	PowerFlex 525	480 VAC	17 A class	Approx. 7.5–11 kW	Approx. 180 × 100 × 200 mm	~3 kg	General machinery
25B-D024N114	PowerFlex 525	480 VAC	24 A class	Approx. 11–15 kW	Approx. 180 × 100 × 200 mm	~3–4 kg	Medium motor applications
25A-D017N114	PowerFlex 523	480 VAC	17 A class	Approx. 7.5–11 kW	Approx. 180 × 100 × 200 mm	~2–3 kg	Compact industrial machinery
20F1ANC030JA0NNNNN	PowerFlex 753	480 VAC	30 A class	Approx. 15–22 kW	Approx. 300 × 200 × 250 mm	~15–20 kg	Process and industrial machinery

These five models illustrate the broader range of motor-control equipment available within the same brand.

The PowerFlex 523 and 525 examples are designed for much smaller machines.

The PowerFlex 753 example occupies a higher industrial application class but is still considerably smaller than the E395 high-power configuration.

They are therefore better viewed as representative models rather than direct replacements.

---

27. E355 vs. E395 Comparison

The E355 and E395 are particularly close in the PowerFlex 755 600 VAC high-power range.

Parameter	E355	E395
Model	20G1G3E355LNDNNNNN	20G1G3E395LNDNNNNN
Voltage Class	600 VAC	600 VAC
Current Class	355 A	395 A
Frame	8	8
Light Duty	400 hp class	450 hp class
Normal Duty	350 hp class	400 hp class
Heavy Duty	300 hp class	350 hp class
Height	2453 mm	2453 mm
Width	600 mm	600 mm
Depth	600/800 mm	600/800 mm
Approx. Weight	~623 kg	~623 kg

The E395 provides an additional current margin compared with the E355.

The two configurations share the same general Frame 8 mechanical platform.

This means that moving from E355 to E395 is generally less dramatic mechanically than moving from E295 to E355.

The main difference is the higher electrical and motor capacity.

---

28. E395 vs. E435 Comparison

The E435 is the next logical higher-capacity configuration in this group.

Parameter	E395	E435
Model	20G1G3E395LNDNNNNN	20G1G3E435LNDNNNNN
Voltage	600 VAC	600 VAC
Current Class	395 A	435 A
Frame	8	8
Light Duty	450 hp class	500 hp class
Normal Duty	400 hp class	450 hp class
Heavy Duty	350 hp class	400 hp class
Height	2453 mm	2453 mm
Width	600 mm	600 mm
Depth	600/800 mm	600/800 mm
Approx. Weight	~623 kg	~623 kg

The E435 is useful when the motor current requirement exceeds the E395 capacity.

Because both belong to the same broad Frame 8 mechanical range, the physical installation concept is similar.

---

29. Application Selection Guide

Large centrifugal pump	Light Duty / Normal Duty
Large fan	Light Duty
Large blower	Light Duty / Normal Duty
Industrial conveyor	Normal Duty
Heavy conveyor	Heavy Duty
Large mixer	Heavy Duty evaluation
Agitator	Normal Duty / Heavy Duty
Compressor	Load-specific selection
Process pump	Motor-current based selection
Material handling	Normal Duty / Heavy Duty
Large production machine	Full load analysis required

The table is intended as a practical selection guide.

The final drive should always be selected from the motor’s actual electrical and mechanical requirements.

31. Why the E395 Is Suitable for Large Industrial Systems

The main advantage of the E395 is the combination of high electrical capacity and the flexible PowerFlex 755 architecture.

The drive is large enough to control substantial industrial motors while still providing the adjustable-speed capability needed by modern automated machinery.

For a pump system, this means the motor can operate according to actual process demand.

For a conveyor, it means acceleration can be controlled.

For a fan, it allows airflow to be adjusted.

For a mixer, it provides the ability to operate at different speeds.

For a process machine, it can become part of the overall automation system.

This flexibility is one of the major reasons why high-power variable frequency drives are used in modern industrial installations.

---

32. Overall Product Summary

The Allen-Bradley 20G1G3E395LNDNNNNN is a high-power PowerFlex 755 AC variable frequency drive designed for large industrial motor-control applications.

It belongs to the PowerFlex 755 series and operates in the 600 VAC three-phase class.

The model is identified with a 395 A current class and is suitable for approximately 450 hp Light Duty, 400 hp Normal Duty, and 350 hp Heavy Duty applications.

The E395 uses a Frame 8 physical platform.

Its approximate dimensions are 2453 mm high × 600 mm wide × 600 or 800 mm deep, and its basic equipment weight is approximately 623 kg.

This makes it a substantial piece of industrial electrical equipment.

The E395 is suitable for large pumps, fans, blowers, conveyors, compressors, mixers, agitators, material-handling systems, cooling equipment and process machinery.

Its high current capacity allows it to serve motors that are far larger than those normally connected to compact variable frequency drives.

Its 600 VAC class makes it suitable for high-power motor systems.

Its Light Duty, Normal Duty and Heavy Duty ratings provide flexibility when matching the drive to different types of industrial loads.

The E395 is especially useful when the motor needs to operate at different speeds rather than running continuously at a fixed speed.

For pumps and fans, this can provide process flexibility.

For conveyors and material-handling equipment, controlled acceleration can reduce mechanical shock.

For mixers and agitators, variable-speed control can help accommodate changing process conditions.

For large industrial machinery, the PowerFlex 755 platform provides a foundation for integrating motor control into the larger automation system.

One of the most important considerations is that the E395 should not be selected simply because the motor has a particular horsepower rating.

The motor nameplate current, voltage, duty classification, torque characteristics, acceleration requirements and overload requirements should all be evaluated.

The physical installation is equally important.

At approximately 2453 × 600 × 600/800 mm and approximately 623 kg, the E395 requires considerably more installation planning than a compact drive.

The electrical cabinet must provide sufficient room for the drive itself as well as power cables, ventilation, control wiring and maintenance access.

For applications requiring slightly less capacity, the E355 can be considered.

For applications requiring more capacity, the E435 and E545 provide higher-current alternatives, while the E595 and larger configurations move into the even larger Frame 9 platform.

For smaller motors, the E242 and E295 provide lower-current options within the same general 600 VAC PowerFlex 755 range.

In practical terms, the 20G1G3E395LNDNNNNN can be regarded as a high-capacity industrial drive for large motors where reliable variable-speed operation, controlled acceleration, high-voltage motor compatibility and flexible industrial integration are important.

Its combination of approximately 395 A current capacity, 600 VAC operation, 400 hp Normal Duty capability, Frame 8 construction, and approximately 623 kg basic weight places it firmly in the large industrial drive category.

It is particularly appropriate for demanding industrial applications where motor power is high and where speed control is an integral part of the production or process system.
