The 31091-400-57 replacement coil is a simple, practical fix that gets your equipment back in service without replacing the entire contactor or starter.\u003c\/p\u003e\n\u003cp\u003eThis coil is designed for NEMA Size 4 devices and is commonly used with 8502SF contactors, 8536SF starters, and 8903SV lighting contactors. If you're working with any of these, this is a direct-fit solution that saves time and avoids unnecessary hassle. It’s rated for 440\/480V AC at 50\/60 Hz, so it works across standard industrial control voltages.\u003c\/p\u003e\n\u003cp\u003eOne thing you’ll notice right away is the build quality. The coil is fully encapsulated, which helps protect it from dust, moisture, and general wear you’d expect in real-world environments. That added protection goes a long way toward extending the life of the component and keeping your system reliable.\u003c\/p\u003e\n\u003cp\u003eFrom a performance standpoint, it delivers the power you need to engage properly, with strong inrush capability and steady sealed consumption once it’s running. And when it comes time to install, the screw clamp terminals make the job straightforward—no complicated setup, just a secure connection and you’re good to go.\u003c\/p\u003e\n\u003cp\u003eWhether you’re replacing a failed coil or keeping a spare on hand for maintenance, this is one of those parts that just makes sense to have ready.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDirect replacement for worn or failed coils\u003c\/li\u003e\n\u003cli\u003eFits 8502SF contactors, 8536SF starters, and 8903SV lighting contactors\u003c\/li\u003e\n\u003cli\u003eRated for 440\/480 VAC, 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003eFully encapsulated to help protect against dirt and moisture\u003c\/li\u003e\n\u003cli\u003eReliable inrush power for consistent operation\u003c\/li\u003e\n\u003cli\u003eEfficient power use during normal operation\u003c\/li\u003e\n\u003cli\u003eScrew clamp connections for quick installation\u003c\/li\u003e\n\u003cli\u003eHelps extend the life of existing equipment\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 31091-400-57\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Coil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNEMA Size:\u003c\/strong\u003e 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e480V AC @ 60 Hz\u003cbr\u003e440V AC @ 50 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInrush Power:\u003c\/strong\u003e 1185–1260 VA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAverage Consumption:\u003c\/strong\u003e 85–89 VA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eHeight: approx. 2.9 in\u003c\/li\u003e\n\u003cli\u003eWidth: approx. 2.6 in\u003c\/li\u003e\n\u003cli\u003eDepth: approx. 2.5 in\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type:\u003c\/strong\u003e Screw Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Encapsulated\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\u003eBuilt to meet standard industrial control requirements\u003c\/li\u003e\n\u003cli\u003eSuitable for commercial and industrial electrical systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e Mexico\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer warranty:\u003c\/strong\u003e 18 months\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\u003eMotor control systems in industrial settings\u003c\/li\u003e\n\u003cli\u003eCommercial lighting control applications\u003c\/li\u003e\n\u003cli\u003eMaintenance and repair jobs where downtime matters\u003c\/li\u003e\n\u003cli\u003eRetrofit situations requiring a voltage-specific coil\u003c\/li\u003e\n\u003cli\u003eFacilities maintaining NEMA Size 4 equipment\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.
