Allen-Bradley 20G11NC037JA0NNNNN PowerFlex 755 AC Drive
An Active Mature Frame 3 drive rated at 18.5 kW normal duty and 15 kW heavy duty, with embedded EtherNet/IP and filtered input.
Product Identification
20G11NC037JA0NNNNN is a PowerFlex 755 drive configured for 400 V AC three-phase operation. Its Frame 3 assembly combines the 37 A rating with embedded EtherNet/IP, forced-air cooling and standard protection.
The exact suffix identifies an open-type, filtered input configuration with DC terminals, a common-mode jumper, dynamic-braking transistor and blank HIM location.

Functions
- Provides adjustable-frequency motor control within the published normal- and heavy-duty ratings.
- Connects directly to EtherNet/IP through the embedded PowerFlex 755 communication interface.
- Supports local control integration and option-module expansion within the 750-Series architecture.
- Uses forced-air cooling for the Frame 3 power structure.
- Provides a DB transistor for an externally engineered dynamic-braking system.
Applications
- EtherNet/IP-connected conveyors, pumps, fans and process machinery using 400 V motors.
- Normal-duty loads matched to the 18.5 kW rating.
- Heavy-duty applications selected against the documented 15 kW capacity.
- Panel systems that require a filtered open-type drive and separate enclosure protection.
- Lifecycle migration from an earlier catalog variant after the complete option set is compared.
Lifecycle
- Rockwell Automation lists 20G11NC037JA0NNNNN as Active Mature.
- The earlier 20G11NC037AA0NNNNN was discontinued with this JA0 catalog number identified as its direct replacement.
- For any exchange, retain motor data, parameters, network settings, option inventory, braking arrangement and enclosure conditions.
- Do not assume the catalog replacement removes the need for firmware, application and installation verification.
