Allen-Bradley 1336F-BRF75-AA-EN-L6 AC Variable Frequency Drive

Allen-Bradley 1336F-BRF75-AA-EN-L6 AC Drive is a 7.5 HP (5.5 kW) variable-frequency drive from the 1336 Plus II family with an integrated bypass for uninterrupted motor power during maintenance. It accepts 380-480 VAC input (DC bus rated 513-620 VDC) and delivers adjustable-speed control for AC motors, with the BRF75 rating corresponding to about 15.4 A output. The enclosure is IP20/NEMA 1 and the unit uses frame size A4, enabling compact installations. The L6 option designates a 115 V AC control power supply (ACDO) for the drive’s electronics, and the model includes a bypass contactor to route motor power around the drive if needed. This model is referenced in Rockwell’s 1336-Series migration guidance to PowerFlex 750-Series drives, which documents upgrade paths from 1336 drives to higher-capacity successors.
