20G1G3C302LNDNNNNN – PowerFlex 755TL Cabinet AC Drive

1. Product Overview

The 20G1G3C302LNDNNNNN is a high-power PowerFlex 755TL Cabinet AC Drive designed for demanding industrial motor-control applications.

It is a cabinet-type, air-cooled variable-frequency drive intended for large three-phase AC motors. The unit belongs to the PowerFlex 750 family and specifically to the PowerFlex 755TL product series.

The model is designed around a 400 V AC three-phase power system and provides a 302 A Normal Duty current rating, with additional current ratings available for Light Duty and Heavy Duty operation. The published rating structure for this configuration is approximately 367 A Light Duty, 302 A Normal Duty, and 260 A Heavy Duty.

The large cabinet construction makes this model fundamentally different from compact machine-mounted frequency converters. It is intended for industrial installations where the drive, cooling system, power components, control components, and associated electrical equipment are integrated into a floor-standing cabinet.

The model is particularly suitable for large pumps, fans, compressors, conveyors, process machinery, material-handling equipment, and other high-power motor applications where controlled motor speed, controlled acceleration and deceleration, and stable process operation are required.

The combination of 367 A Light Duty, 302 A Normal Duty, and 260 A Heavy Duty allows the drive to be selected according to the actual load profile rather than simply selecting a drive based on the motor’s nominal horsepower.

For continuous industrial machinery, the Normal Duty rating is generally an important reference point. Applications with significant overload requirements should be evaluated using the appropriate Heavy Duty rating rather than selecting solely from the motor’s nominal power.

3. Product Series

The 20G1G3C302LNDNNNNN belongs to the PowerFlex 755TL series.

The PowerFlex 755TL family is intended for applications requiring high-performance motor control in a cabinet-style industrial drive package.

The “TL” configuration is associated with a low-harmonic cabinet drive architecture. This makes the series particularly relevant to industrial facilities where electrical power quality, harmonic management, and high-power motor control are important considerations.

The PowerFlex 755TL series is positioned above compact variable-frequency drives in terms of physical size, power capability, cabinet integration, and system-level application requirements.

It is therefore normally used in large industrial equipment and plant-level systems rather than small standalone machines.

4. Brand

Brand: Allen-Bradley

Allen-Bradley is the brand associated with the product.

For industrial automation engineers, the brand is widely associated with programmable control systems, motor control, variable-frequency drives, industrial networking, safety systems, and automation components.

Within this product family, the PowerFlex designation identifies the variable-frequency drive platform.

The most important electrical distinction is the three-duty rating.

The 367 A Light Duty rating is intended for applications with comparatively moderate overload requirements.

The 302 A Normal Duty rating provides the primary continuous-duty reference for many industrial applications.

The 260 A Heavy Duty rating is intended for applications where the motor experiences higher load demand and greater overload requirements.

6. Power Rating Explanation

The drive has three useful power classes:

Duty Class Current Approx. Power
Light Duty 367 A 200 kW
Normal Duty 302 A 160 kW
Heavy Duty 260 A 132 kW

This rating structure is important because motor applications do not all place the same demands on a drive.

A centrifugal fan, for example, can have a very different load profile from a conveyor carrying heavy material.

A compressor can also require different acceleration and overload characteristics compared with a pump.

Therefore, a drive should not be selected only from the motor nameplate horsepower. The actual load torque, starting condition, acceleration time, overload requirement, operating speed range, and duty cycle should also be considered.

7. Physical Dimensions and Weight

Mechanical Parameter Specification
Model 20G1G3C302LNDNNNNN
Cabinet width Approx. 1200 mm
Cabinet depth Approx. 675 mm
Cabinet height Approx. 2132 mm
Overall dimensions Approx. 1200 × 675 × 2132 mm
Approximate cabinet volume Approx. 1.73 m³
Approximate weight 861 kg
Mounting Floor standing
Cooling Forced air
Installation space Large industrial electrical-room space
Transportation Heavy equipment handling required
Cabinet access Service access required
Ventilation Required
Floor loading Must accommodate approximately 861 kg plus installation allowances

The physical dimensions are significant.

At approximately 2132 mm high, the cabinet requires careful consideration of room height, transportation routes, door openings, lifting arrangements, and service clearance.

The approximate 861 kg weight also means that the installation floor should be checked for appropriate load-bearing capacity.

The cabinet should not be treated like a conventional wall-mounted variable-frequency drive. It should be planned as a complete industrial electrical cabinet.

8. Product Introduction

The 20G1G3C302LNDNNNNN is designed for high-power variable-speed motor control in industrial environments.

The drive converts incoming three-phase AC electrical power into controlled electrical output for a motor. By controlling the output frequency and voltage, the system can regulate motor speed and torque according to the process requirement.

This approach allows a motor-driven machine to operate at different speeds rather than simply switching between full-speed operation and shutdown.

For many industrial processes, this provides better process control.

For example, a pump does not necessarily need to operate at full speed at all times. A fan may require different airflow during different production conditions. A conveyor may require controlled acceleration and different operating speeds depending on material flow.

The drive provides the electrical control platform required for these applications.

9. Low-Harmonic Architecture

One of the important characteristics of the PowerFlex 755TL series is its low-harmonic architecture.

Large variable-frequency drives can have a significant effect on an industrial electrical distribution system.

When many high-power drives are installed in the same facility, harmonic current can become an important engineering consideration.

The low-harmonic design of the PowerFlex 755TL series is intended for applications where controlling the electrical characteristics seen by the upstream power system is important.

This can be particularly valuable in large manufacturing plants, water-treatment facilities, process plants, production facilities, and other installations containing several large electrical loads.

10. Cooling System

The 20G1G3C302LNDNNNNN uses an air-cooled design.

At approximately 160 kW Normal Duty, the amount of heat generated by the drive system is significant, so airflow management is an important part of the installation.

The cabinet should have adequate ventilation and sufficient clearance for the cooling system.

The surrounding environment should also be considered.

Dust, high ambient temperature, blocked ventilation paths, excessive humidity, and poor cabinet-room airflow can negatively affect drive operation and service life.

For this reason, the drive-room HVAC and ventilation system should be considered together with the drive installation.

11. Main Product Advantages

11.1 High-Power Motor Control

The 302 A Normal Duty rating makes this drive suitable for large industrial motors.

The 160 kW Normal Duty class allows it to serve applications that are beyond the practical range of small and medium machine drives.

This makes it suitable for plant-level motor applications where high output power and controlled speed are required.

11.2 Low-Harmonic Operation

The low-harmonic architecture is one of the major system-level advantages of this series.

It can be particularly useful where a large number of variable-frequency drives operate from the same electrical distribution system.

This allows electrical engineers to consider the drive not only as a motor controller but also as part of the plant’s overall power-quality design.

11.3 Cabinet Integration

The cabinet design provides an integrated industrial installation.

Instead of installing a large drive module separately and then building a separate enclosure around it, the cabinet configuration provides a dedicated floor-standing drive arrangement.

This can simplify large system architecture and make the drive suitable for centralized electrical rooms.

11.4 Multiple Duty Ratings

The three duty ratings provide flexibility.

The same drive configuration can be evaluated for different application load characteristics:

  • 367 A Light Duty
  • 302 A Normal Duty
  • 260 A Heavy Duty

This is useful because industrial machinery does not have a single universal torque profile.

11.5 Large Industrial Application Range

The drive can be used in a wide range of machinery.

Typical applications include:

  • Large pumps
  • Large fans
  • HVAC process equipment
  • Compressors
  • Conveyors
  • Crushers
  • Mixers
  • Process lines
  • Material-handling systems
  • Water-treatment systems
  • Industrial ventilation
  • Production machinery

12. Typical Applications

Large Pump Systems

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

The drive can control pump speed according to flow or pressure requirements.

Instead of operating a pump continuously at maximum speed, the control system can adjust motor speed according to process demand.

This can improve process flexibility and provide more precise control.

Industrial Fans

Large fans can require substantial motor power.

The drive can regulate fan speed according to ventilation or process requirements.

Typical applications include industrial exhaust systems, process ventilation, cooling systems, air-handling equipment, and large-scale ventilation systems.

Compressors

Compressors can have demanding torque characteristics and may require controlled acceleration and speed regulation.

A high-power drive can be integrated into the compressor control system where variable-speed operation is required.

Conveyor Systems

Large conveyors often benefit from controlled starting and stopping.

A variable-frequency drive can provide controlled acceleration, reducing mechanical shock during startup.

Speed adjustment can also allow the conveyor to match the production process.

Process Machinery

Industrial process equipment frequently requires a motor to operate at different speeds during different stages of production.

The drive can provide a controllable motor-speed platform for such machinery.

Water and Wastewater Systems

Large pumps, blowers, and process motors are common in water-treatment installations.

A low-harmonic high-power drive can be useful where several large motors operate within the same facility.

13. Application Advantages

The main advantage of using a high-power variable-frequency drive is that the motor becomes part of the process-control system.

Instead of treating the motor as a simple ON/OFF device, the drive allows motor speed and torque to become controllable process variables.

This can be useful for:

  • Flow regulation
  • Pressure regulation
  • Speed regulation
  • Controlled acceleration
  • Controlled deceleration
  • Process synchronization
  • Production-line coordination
  • Reduced mechanical shock
  • Improved operational flexibility

14. Installation Requirements

Because this is a large cabinet drive, installation planning is more involved than with compact inverters.

The following factors should be considered before installation:

Installation Item Recommended Consideration
Model 20G1G3C302LNDNNNNN
Power supply 400 V AC, 3-phase system
Cabinet location Dedicated industrial electrical area
Floor loading Must support approximately 861 kg
Cabinet height Approximately 2132 mm
Cabinet width Approximately 1200 mm
Cabinet depth Approximately 675 mm
Ventilation Required
Ambient temperature Must remain within applicable operating limits
Dust control Important
Cable routing Adequate power and control separation
Grounding Proper industrial grounding required
Motor cable Correctly sized for motor current and installation conditions
Maintenance access Adequate service clearance required
Lifting Heavy-equipment handling required
Electrical protection Must be coordinated with the drive and power system
EMC considerations Should be included in system design
Motor compatibility Verify motor voltage, current, insulation, and duty

The cabinet dimensions and weight should be incorporated into the plant layout before equipment delivery.

The approximately 861 kg weight also means that ordinary manual handling is not appropriate for installation.

15. Five Related PowerFlex 755 Models

The following models are closely related PowerFlex 755-family configurations.

They cover different current ratings and therefore different motor-power ranges.

They should be regarded as related models rather than automatically interchangeable replacements.

Model Series Voltage Light Duty Normal Duty Heavy Duty Approx. Dimensions Approx. Weight
20G1G3C367LNDNNNNN PowerFlex 755TL 400 V AC 460 A / 250 kW 367 A / 200 kW 302 A / 160 kW Approx. 1200 × 675 × 2132 mm Approx. 861 kg
20G1G3C460LNDNNNNN PowerFlex 755TL 400 V AC 540 A / 315 kW 460 A / 250 kW 367 A / 200 kW Approx. 1200 × 675 × 2132 mm Approx. 861 kg
20G1G3C540LNDNNNNN PowerFlex 755TL 400 V AC 650 A / 400 kW 540 A / 315 kW 460 A / 250 kW Configuration-dependent cabinet Approx. 861 kg class
20G1G3C585LNDNNNNN PowerFlex 755TL 400 V AC Higher current class 585 A class Application-dependent Configuration-dependent cabinet Configuration-dependent
20G1G3C750LNDNNNNN PowerFlex 755TL 400 V AC Higher current class 750 A class Application-dependent Large cabinet configuration Configuration-dependent

Among these models, the 20G1G3C367LNDNNNNN and 20G1G3C460LNDNNNNN are particularly useful comparison points because they remain within the same 400 V PowerFlex 755TL cabinet family while providing higher current capacity.

The exact physical dimensions and shipping weight should be confirmed from the mechanical configuration before equipment replacement or cabinet planning because high-current cabinet assemblies can vary depending on the complete configuration.

16. Comparison of Related Models

Model Normal Duty Current Normal Duty Power Voltage Cooling Mounting Dimensions Weight
20G1G3C302LNDNNNNN 302 A 160 kW 400 V Air cooled Floor cabinet 1200 × 675 × 2132 mm 861 kg
20G1G3C367LNDNNNNN 367 A 200 kW 400 V Air cooled Floor cabinet Approx. 1200 × 675 × 2132 mm Approx. 861 kg
20G1G3C460LNDNNNNN 460 A 250 kW 400 V Air cooled Floor cabinet Approx. 1200 × 675 × 2132 mm Approx. 861 kg
20G1G3C540LNDNNNNN 540 A 315 kW 400 V Air cooled Floor cabinet Configuration-dependent Approx. 861 kg class
20G1G3C585LNDNNNNN 585 A class Application-dependent 400 V Air cooled Floor cabinet Configuration-dependent Configuration-dependent

The models become progressively larger in electrical capacity as the current rating increases.

When selecting among them, the motor’s full-load current should be compared with the appropriate duty rating.

A 302 A drive should not be replaced by a larger-current model merely because the larger model appears to offer more capacity. The complete system must also be evaluated for protection, cable sizing, cabinet arrangement, power distribution, cooling, and control configuration.

17. Five Popular Models from the Same Brand

23. Product Family Structure

The relationship between the main product families can be summarized as follows:

Product Family Typical Application Scale Typical Drive Size Typical Application
PowerFlex 525 Small Compact Machine-level automation
PowerFlex 753 Medium to large Industrial Pumps, fans, conveyors, machinery
PowerFlex 755 Large Industrial High-performance motor control
PowerFlex 755TL Large to very large Cabinet Low-harmonic high-power applications

The 20G1G3C302LNDNNNNN belongs to the last category.

Its cabinet construction, current rating, power class, and physical size clearly place it in the large industrial-drive category.

24. Main Advantages in Industrial Plants

High Power Density

The drive provides substantial motor-control capacity within a dedicated cabinet system.

This makes it suitable for centralized drive installations where several large motor systems are installed within the same industrial electrical area.

Power Quality Consideration

The low-harmonic architecture makes this type of drive suitable for applications where the electrical network must be carefully managed.

This is especially relevant to plants with multiple large drives and other sensitive electrical equipment.

Wide Application Range

The drive is not restricted to one machine type.

The same basic platform can be used in pumping, ventilation, conveying, processing, compression, and material-handling applications, provided the motor and load requirements match the drive ratings.

Industrial Construction

The cabinet construction is designed for industrial installations.

It provides a substantial enclosure for the drive system and supports installation in dedicated electrical rooms or industrial equipment areas.

Multiple Duty Ratings

The Light Duty, Normal Duty, and Heavy Duty classifications allow the engineer to match the drive more closely to the actual load profile.

25. Advantages for Pump Applications

For pump applications, variable-speed control can allow the pump to operate closer to actual process requirements.

For example, a water-treatment system may require different flow rates during different production periods.

Instead of maintaining the motor at a fixed speed and controlling flow through mechanical throttling, the drive can adjust motor speed according to the process requirement.

This provides a more flexible control architecture and can reduce unnecessary mechanical stress.

26. Advantages for Conveyor Applications

For conveyors, controlled acceleration can reduce mechanical shock.

A large conveyor may have a significant amount of mechanical mass.

Starting the motor abruptly can place stress on couplings, gearboxes, belts, shafts, and other mechanical components.

A variable-frequency drive allows the acceleration profile to be controlled according to the machine requirement.

27. Advantages for Fan Applications

Fan systems frequently operate at different required airflow levels.

Variable-speed control allows the fan speed to be adjusted to match the required airflow.

This is useful for industrial ventilation, process cooling, extraction systems, and other applications where full-speed operation is not continuously necessary.

28. Advantages for Compressor Applications

Compressors often require carefully managed acceleration and operating speed.

A high-power drive can provide controlled motor operation and integrate motor speed into the overall compressor-control strategy.

The exact suitability depends on compressor type, motor characteristics, pressure requirements, acceleration requirements, and the manufacturer’s application requirements.

29. Maintenance Considerations

Large cabinet drives require a planned maintenance strategy.

Important maintenance areas include:

  • Cooling fans
  • Air passages
  • Electrical connections
  • Power terminals
  • Control wiring
  • Grounding
  • Cabinet ventilation
  • Environmental contamination
  • Cooling-system performance
  • Alarm history
  • Motor connections
  • Communication connections

Dust accumulation can be particularly important for air-cooled equipment.

The cooling system should be inspected regularly in environments containing dust, fibers, oil mist, or other airborne contaminants.

30. Replacement Selection

When replacing an existing 20G1G3C302LNDNNNNN, the replacement should not be selected only by comparing horsepower.

The following characteristics should be matched:

Selection Parameter Why It Matters
Model 20G1G3C302LNDNNNNN
Input voltage Must match the electrical distribution system
Motor voltage Must match the motor
Motor current Determines required drive current capacity
Duty class Determines usable current and overload capability
Power rating Must correspond to motor and load requirements
Harmonic requirements Important for plant power quality
Cabinet dimensions Required for mechanical replacement
Cabinet weight Important for transportation and installation
Cooling Must match installation environment
Braking Must match stopping requirements
Regeneration Important for regenerative loads
Communication Must match automation architecture
Safety Must match machine safety requirements
Motor feedback Required when feedback control is used
Environmental conditions Determines enclosure and cooling requirements

A replacement that has the same current rating but a different input architecture may not be a direct functional replacement.

Likewise, a drive with the same horsepower but a different voltage class cannot be treated as an equivalent product.

32. Final Product Description

The 20G1G3C302LNDNNNNN is a large cabinet-type variable-frequency drive belonging to the PowerFlex 755TL series within the PowerFlex 750 family.

Its primary electrical configuration is 400 V AC, three-phase, with a 367 A Light Duty rating, 302 A Normal Duty rating, and 260 A Heavy Duty rating. The corresponding power classes are approximately 200 kW, 160 kW, and 132 kW respectively.

The unit is designed for high-power industrial motor applications where precise motor-speed control, controlled acceleration and deceleration, and low-harmonic operation are important.

Its physical construction is substantial, with an approximate cabinet size of 1200 mm wide × 675 mm deep × 2132 mm high and an approximate weight of 861 kg.

Because of this size and weight, the product should be planned as a complete industrial electrical cabinet rather than as a conventional compact inverter.

The PowerFlex 755TL platform is particularly suitable for large industrial pumps, fans, compressors, conveyors, process machinery, water-treatment systems, material-handling systems, and other large motor-driven equipment.

The low-harmonic design is an important characteristic for plants where multiple high-power drives share the same electrical distribution network.

For equipment replacement, the complete catalog number should always be compared with the proposed replacement. Voltage, current, duty class, power rating, cabinet dimensions, cooling, braking, harmonic architecture, communication options, and motor requirements should all be checked together.

For engineering documentation, procurement, and equipment replacement, the 20G1G3C302LNDNNNNN should therefore be treated as a specific high-power cabinet-drive configuration rather than simply as a generic 302 A frequency converter.
