The Allen-Bradley 509-AOD motor starter is built to help prevent that. It’s a straightforward, reliable solution for controlling and protecting motors without adding unnecessary complexity to your setup.\u003c\/p\u003e\n\u003cp\u003eThis is a NEMA Size 0 direct-on-line (DOL) starter, rated for 18 amps continuous current and up to 5 horsepower at 575V (3-phase). It’s commonly used in everyday industrial applications where you just need equipment to start, run, and stay protected.\u003c\/p\u003e\n\u003cp\u003eWhat makes this unit especially useful is the Class 30 overload protection. It gives your motor enough time to handle normal startup conditions, but steps in when there’s a real overload situation—helping reduce the risk of damage. It also includes temperature compensation, which means it adjusts more accurately based on the environment instead of tripping too early or too late.\u003c\/p\u003e\n\u003cp\u003eThe construction is solid where it counts—silver alloy contacts for conductivity, long mechanical life, and simple screw terminal connections that make installation and maintenance easier.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBuilt-in overload protection (Class 30) helps protect motors from overheating\u003c\/li\u003e\n\u003cli\u003eDirect-on-line starting keeps things simple and easy to manage\u003c\/li\u003e\n\u003cli\u003e18A continuous current rating for common industrial motor applications\u003c\/li\u003e\n\u003cli\u003eHandles up to 5HP at 575V (3-phase)\u003c\/li\u003e\n\u003cli\u003eTemperature-compensated protection for more accurate performance\u003c\/li\u003e\n\u003cli\u003eExternal reset capability for easier troubleshooting and restart\u003c\/li\u003e\n\u003cli\u003eSupports emergency stop applications\u003c\/li\u003e\n\u003cli\u003eUp to 8 auxiliary contacts for added control flexibility\u003c\/li\u003e\n\u003cli\u003eRail mountable design for straightforward installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e 509-AOD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Direct Online Starter (DOL)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNEMA Size:\u003c\/strong\u003e Size 0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current:\u003c\/strong\u003e 18A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService Limit Current:\u003c\/strong\u003e 21A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Horsepower:\u003c\/strong\u003e 5HP @ 575V, 3-phase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl Voltage:\u003c\/strong\u003e 110V (50 Hz) \/ 120V (60 Hz) AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload Relay:\u003c\/strong\u003e Eutectic alloy, Class 30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShort-Circuit Release:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Inrush Current:\u003c\/strong\u003e 140A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating VA Burden:\u003c\/strong\u003e 29VA (sealed, 60 Hz coils)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnections:\u003c\/strong\u003e Screw terminals (power \u0026amp; control)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Size:\u003c\/strong\u003e 14–10 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuxiliary Contacts:\u003c\/strong\u003e Up to 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMechanical Life:\u003c\/strong\u003e 10 million operations\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e DIN rail capable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure:\u003c\/strong\u003e Open type\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial Compliance and Certifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e It aligns with IEC 60947-4-3 Class 2 coordination standards, which helps ensure proper protection under fault conditions.
