The Allen-Bradley 509-DOD is one of those starters that earns its keep by doing its job reliably, without constant attention.\u003c\/p\u003e\n\u003cp\u003eThis is a NEMA Size 3 direct-on-line (DOL) motor starter designed for straightforward motor control and protection. It handles up to 90 amps of continuous current and supports motors up to 7.5 horsepower, making it a solid choice for common industrial loads like pumps, compressors, and conveyors.\u003c\/p\u003e\n\u003cp\u003eWhat makes this unit especially practical is its temperature-compensated overload protection. Instead of reacting too quickly—or too late—it adjusts based on actual conditions. That means better protection for your motor and fewer unnecessary shutdowns.\u003c\/p\u003e\n\u003cp\u003eYou’re also getting factory-installed auxiliary contacts, which saves time during install, along with external reset capability and support for emergency stop setups. Internally, the use of silver alloy contacts and treated metal components helps extend the life of the unit, even in tougher environments.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBuilt for consistent motor starting and protection in everyday industrial use\u003c\/li\u003e\n\u003cli\u003e90A continuous current rating handles demanding equipment\u003c\/li\u003e\n\u003cli\u003eTemperature-compensated overload relay helps prevent overheating without nuisance trips\u003c\/li\u003e\n\u003cli\u003eComes with 2 normally open auxiliary contacts already installed\u003c\/li\u003e\n\u003cli\u003eSupports emergency stop applications and external reset\u003c\/li\u003e\n\u003cli\u003eSilver alloy contacts improve durability and electrical performance\u003c\/li\u003e\n\u003cli\u003eRated for up to 5 million mechanical operations\u003c\/li\u003e\n\u003cli\u003eSimple screw terminal connections make installation straightforward\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-DOD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Direct Online (DOL) Motor Starter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNEMA Size:\u003c\/strong\u003e Size 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current:\u003c\/strong\u003e 90 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService Limit Current:\u003c\/strong\u003e 104 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax HP:\u003c\/strong\u003e 7.5 HP @ 115V (1-phase)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl Voltage:\u003c\/strong\u003e 110V (50 Hz) \/ 120V (60 Hz)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuxiliary Contacts:\u003c\/strong\u003e 2 NO (expandable up to 8)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload Relay:\u003c\/strong\u003e Eutectic alloy, temperature compensated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Class:\u003c\/strong\u003e Class 30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Inrush Current:\u003c\/strong\u003e 947 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type:\u003c\/strong\u003e Screw terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Size:\u003c\/strong\u003e 8…1 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMechanical Life:\u003c\/strong\u003e 5,000,000 operations\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e Up to 65°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Vertical, rail mounting optional\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure:\u003c\/strong\u003e Open type\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Material:\u003c\/strong\u003e Silver alloy\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\u003eMeets IEC 60947-4-3 (Class 2 coordination) standards\u003c\/li\u003e\n\u003cli\u003eBuilt to NEMA Size 3 specifications\u003c\/li\u003e\n\u003cli\u003eCorrosion-resistant treated metal components\u003c\/li\u003e\n\u003cli\u003eSuitable for installations up to 10,000 ft (with derating)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThis starter fits right into applications where reliability matters more than bells and whistles:\u003c\/li\u003e\n\u003cli\u003eManufacturing equipment\u003c\/li\u003e\n\u003cli\u003eHVAC systems\u003c\/li\u003e\n\u003cli\u003ePump and fluid handling setups\u003c\/li\u003e\n\u003cli\u003eConveyor systems\u003c\/li\u003e\n\u003cli\u003eCompressors and general motor-driven machinery\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e\n\u003cbr\u003e\n\u003cdiv\u003e\n\u003cblockquote\u003e\n\u003cp style=\"font-size: 12px;\"\u003e\u003cem\u003eUse of Original Equipment Manufacturer (OEM) trademarks, names, and logos is for informational and identification purposes only.
