Allen Bradley 20G1AND477JA0NNNNN Inverter Drive – 300kW, IP20

The AB 20G1AND477JA0NNNNN is a high-capacity PowerFlex 755 AC drive engineered for controlling large motors in heavy-duty industrial environments. Rated at 477 A, this drive delivers up to 300 kW (400 HP) at normal duty operation with a 3-phase 480 VAC input and integrated DC precharge functionality.

This open-type IP20/IP00 model includes an internal dynamic braking transistor and is designed without a Human Interface Module (HIM), using a blank cover instead. Built for cabinet installation, it is ideal for high-inertia and high-power motor control applications, offering reliable performance and modular integration with Rockwell Automation systems.
