Heater elements generate a calibrated amount of heat proportional to motor current, allowing the overload relay to trip and protect motors from sustained overcurrent conditions. The SMFH26 is a direct-replacement-style component sized for a specific current range within the SMF Class designation. Installation is performed by licensed electricians or qualified industrial maintenance technicians as part of motor control center or combination starter servicing.\u003c\/p\u003e\n\u003cp\u003eClass SMF heater elements like the SMFH26 are used in SIEMENS and compatible thermal overload relays installed in motor starters, combination starters, and motor control centers. Typical applications include three-phase motor protection in commercial HVAC equipment, pump systems, compressors, and light industrial machinery. The heater element is selected based on the full-load amperage of the motor being protected and the ambient temperature correction factors for the installation environment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass SMF designation for use in compatible SIEMENS thermal overload relay assemblies\u003c\/li\u003e\n  \u003cli\u003eCalibrated heater element provides current-proportional thermal response for accurate motor overload protection\u003c\/li\u003e\n  \u003cli\u003eCompact form factor fits directly into overload relay heater pockets without modification\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 0.044 pounds for easy handling during service calls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement heater element for SIEMENS Class SMF thermal overload relays.

De-energize and lock out the motor control circuit per NFPA 70E and NEC requirements before removing or installing heater elements. Verify the heater element class and current range against the motor full-load amperage nameplate data before installing. Do not use heater elements that show signs of prior overload damage, discoloration, or deformation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeater Class\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: 0.044 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 75455425944\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: SIEMENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SMFH26\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383072194866,"sku":"SMFH26","price":50.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312677574.jpg?v=1782587218","url":"https:\/\/voomisupply.com\/products\/siemens-smfh26-class-smf-overload-heater-element","provider":"Voomi Supply","version":"1.0","type":"link"}
