These heater elements are sized to match specific full-load ampere ratings and work in conjunction with thermal overload relays to provide overcurrent protection for three-phase and single-phase motor circuits. The SMFH48 is a precision-matched component that triggers the overload relay at the correct thermal threshold, protecting motor windings from sustained overload conditions. Installation is performed by licensed electricians and industrial maintenance technicians working on motor control centers and combination starters.\u003c\/p\u003e\u003cp\u003eThe SMFH48 is suited for use in industrial and commercial motor control applications where thermal overload protection is required. It fits into SIEMENS Class SMF overload relay heater sockets and is selected based on the full-load ampere rating of the motor being protected. These heater elements are commonly installed in motor control centers, panel-mounted starters, and combination motor controllers in light manufacturing, HVAC mechanical rooms, and process equipment panels.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass SMF heater element designed for SIEMENS thermal overload relay assemblies\u003c\/li\u003e\n\u003cli\u003eSized for precise thermal overcurrent protection matched to motor full-load ampere rating\u003c\/li\u003e\n\u003cli\u003eCompact form factor for direct installation into compatible heater sockets\u003c\/li\u003e\n\u003cli\u003eProvides thermal trip response to protect motor windings from overload damage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement heater element for SIEMENS Class SMF thermal overload relay assemblies. Verify the correct heater element selection table for the target motor full-load ampere rating before installation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with NEC Article 430 governing motor branch circuit and overload protection requirements. De-energize and lockout\/tagout the motor control circuit before removing or installing heater elements. Heater element selection must be verified against the motor nameplate full-load ampere rating and the manufacturer heater selection table. Do not substitute heater elements of a different class or designation, as incorrect sizing will compromise overload protection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: SMF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.311 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.154 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.154 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.066 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 75455425967\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SIEMENS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SMFH48\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383799677234,"sku":"SMFH48","price":51.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312678904.jpg?v=1782607700","url":"https:\/\/voomisupply.com\/products\/siemens-smfh48-class-smf-heater","provider":"Voomi Supply","version":"1.0","type":"link"}
