It monitors current draw and trips the control circuit when heat buildup indicates an overload, preventing motor winding damage. This type of relay is a standard component in motor starter assemblies used across commercial and industrial electrical systems. Licensed electricians and industrial maintenance technicians are the primary installers and service personnel for this class of device.\u003c\/p\u003e\n\u003cp\u003eThe H2109B-3 is suited for use in motor control center (MCC) assemblies and combination motor starters in commercial and light industrial applications. It is typically installed in conjunction with a contactor to form a complete motor starter. Typical applications include HVAC fan and pump motors, compressor circuits, and general-purpose three-phase motor control panels.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThermal overload protection guards motors against sustained overcurrent and heat damage\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 1.6 inches x 1.7 inches x 3.1 inches for panel-efficient installation\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 0.25 pounds for easy handling during retrofit or new installation\u003c\/li\u003e\n  \u003cli\u003eDesigned for integration with compatible motor starters and contactors\u003c\/li\u003e\n  \u003cli\u003eProvides automatic trip function to interrupt control circuit on overload condition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style overload relay for use in motor starter assemblies.

De-energize and lock out the motor control panel before removing or installing the overload relay. Verify the trip class and current range of the relay match the motor nameplate FLA before placing the circuit back in service. Do not bypass or jumper the overload relay contacts during testing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78211300480\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: EATON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H2109B-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51383803969842,"sku":"H2109B-3","price":100.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312678359.jpg?v=1782607829","url":"https:\/\/voomisupply.com\/products\/eaton-h2109b-3-overload-relay","provider":"Voomi Supply","version":"1.0","type":"link"}
