Allen-Bradley 509-AOD-A0D Full Voltage Starter

Allen-Bradley 509-AOD-A0D Full Voltage Starter is a NEMA-size 0, non-reversing motor starter designed for direct-on-line starting of three-phase motors. This open-type unit includes a eutectic alloy overload relay and is configured for a 115-120 V, 60 Hz coil, enabling convenient control from standard low-voltage circuits while switching higher-power motor circuits. As part of the Bulletin 509 family, it is a 3-pole starter suitable for line voltages up to 600 V and typically supports about 18 A continuous current at size 0, with horsepower ratings around 1.5 HP at 230 V and 2 HP at higher voltages (380–415 V and 460–575 V). The starter ships with one normally open auxiliary contact and is designed for use with Bulletin 509 motor-control systems, providing reliable control in light-to-medium duty applications. Common use cases include small conveyors, fans, pumps, and other equipment requiring simple, direct-on-line motor starting in industrial panels.
