Allen-Bradley 505-AOD Full Voltage Reversing Starter

Allen-Bradley 505-AOD Full Voltage Reversing Starter is a NEMA-rated reversing starter from the Bulletin 505 family designed to control and reverse 3-phase motors from line voltage. This Size 0, open-type unit is rated for up to 600 VAC and provides a continuous current rating of 18 A, making it suitable for medium-duty motor applications in industrial control panels, conveyors, pumps, fans, and similar equipment where forward and reverse operation is needed. The 505-AOD variant features an eutectic alloy overload relay and a coil rated for 115–120 VAC at 60 Hz, enabling motor protection within a compact, field-installable package. As part of Allen-Bradley’s 505 motor control lineup, it can be integrated with other 505 components to create coordinated motor control for open-type installations. This starter is intended for open installation without a dedicated enclosure, providing straightforward wiring access in control cabinets or on panel boards, while delivering reliable switching of line voltage to the motor.
