Allen-Bradley 505-AOD-23 Full-Voltage Reversing Starter

Allen-Bradley 505-AOD-23 is a NEMA-size 0 full-voltage reversing starter in open, non-enclosed form. It is designed to control a motor using a 115–120 V, 60 Hz control circuit and ships without an overload relay. As part of Rockwell Automation's 505 family, this unit provides forward and reverse motor operation by energizing the appropriate contactors in a compact package that does not include an enclosure. The 505-AOD-23 variant specifies 115–120 V operation, aligning with common North American power standards, and its size 0 designation indicates a small-footprint unit suitable for lower-power applications. This open-style starter is intended for use in electrical control panels or other environments where space efficiency matters and a direct-voltage reversing solution is required.
