Product Overview

The Allen-Bradley 20G11NC104JA0NNNNN​ is a high-performance air-cooled PowerFlex 755 AC drive engineered by Rockwell Automation, representing the gold standard of variable frequency drive (VFD) technology for demanding industrial motor control applications. As a member of the PowerFlex 755 series—Rockwell’s flagship drive platform—the Allen-Bradley 20G11NC104JA0NNNNN​ delivers 104 amps of output current at 400 V AC three-phase input, providing 55 kW of normal-duty (ND) power or 45 kW of heavy-duty (HD) power in a compact Frame 5 open-type enclosure. Currently in the Active Mature product lifecycle stage and classified as repairable/replaceable by the manufacturer, the Allen-Bradley 20G11NC104JA0NNNNN​ is built for long-term operational deployment with a standard 1-year warranty and estimated lead time of just 5 days.Designed with embedded EtherNet/IP as a standard feature, the Allen-Bradley 20G11NC104JA0NNNNN​ simplifies integration into Logix control architectures, allowing drive instructions embedded directly within ControlLogix or CompactLogix programmable automation controllers (PACs) to manage the drive natively. The unit features AC input with DC terminals, standard corrosive-gas protection, forced-air cooling, and an IP20/IP00 NEMA/UL open-type enclosure measuring 270 mm × 550 mm × 212 mm and weighing 21 kg. An internally mounted EMC filter with CM jumper installed (preferred configuration), combined with an integrated dynamic braking (DB) transistor, equips the Allen-Bradley 20G11NC104JA0NNNNN​ to handle both regenerative energy management and electromagnetic compliance in electrically harsh industrial environments. The drive ships with a blank HIM (no human interface module), allowing system integrators to select the appropriate operator interface for their specific application.The Allen-Bradley 20G11NC104JA0NNNNN​ is ideally suited for applications requiring precise positioning, speed, or torque control—including pumps, fans, conveyors, compressors, extruders, and hoists. Its slot-based hardware architecture with five option slots supports feedback, I/O, safety, and communications modules, giving engineers the flexibility to tailor the drive to evolving application needs. With support for V/Hz control, vector control with FORCE technology, sensorless vector control, permanent magnet motor control, and Integrated Motion on EtherNet/IP, the Allen-Bradley 20G11NC104JA0NNNNN​ delivers the versatility and performance that modern manufacturing, material handling, metals, mining, oil and gas, and refining operations demand. The drive’s predictive diagnostics capabilities—extended through FactoryTalk Analytics GuardianAI—enable plant operators to monitor VFD health, project remaining lifespan of critical components, and receive actionable insights before failures occur, transforming the Allen-Bradley 20G11NC104JA0NNNNN​ from a mere motor controller into a cornerstone of smart, connected industrial operations.
