Allen-Bradley 709-AAD3 Across-the-Line AC Starter

The Allen-Bradley 709-AAD3 Across-the-Line AC Starter is an enclosed automatic starter from the Bulletin 709 family, offered in Size 0. It provides direct-on-line control for AC motors, with the switching and control components housed in a single enclosure. The 709-AAD3 designation identifies a specific configuration within Allen-Bradley’s 709 across-the-line starter lineup, a legacy product line now under Rockwell Automation. This Size-0 unit is designed for control panels and motor-control cabinets where a compact, protected starter is required to perform automatic motor control tasks: closing the line circuit to energize the motor and opening it to stop. In typical installations, the starter is wired to a control circuit that issues start and stop commands, enabling straightforward motor operation in industrial settings. The enclosure provisions and exact electrical ratings for this model are defined by its Bulletin 709 configuration, making it suitable for incorporation into existing 709-based control schemes or as a retrofit in facilities with legacy Allen-Bradley equipment.
