Thermal heater units like the SMFH09 protect motors and other electrical loads from sustained overcurrent conditions by generating a calibrated thermal response that trips the overload relay. Licensed electricians and industrial maintenance technicians install these elements as direct replacement components inside compatible Siemens overload relay assemblies. The part weighs approximately 0.419 pounds and is a compact unit suited for panel and motor control center installations.\u003c\/p\u003e\n\u003cp\u003eClass SMF heater elements are used in motor control applications across light commercial and industrial settings. They are installed inside bimetallic overload relays mounted in motor starters and combination starter units. The heater element is matched to the full-load amperage of the motor being protected, so selecting the correct heater class and suffix is critical to proper overload protection. This element is appropriate for new installations as well as field replacement of worn or failed thermal units in existing assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass SMF designation for use in compatible Siemens bimetallic overload relay assemblies\u003c\/li\u003e\n  \u003cli\u003eProvides calibrated thermal overload protection for motor circuits\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suitable for motor control center and enclosed starter installations\u003c\/li\u003e\n  \u003cli\u003eDirect replacement heater element for field service and maintenance\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 0.419 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement heater element for Class SMF bimetallic overload relay assemblies.

De-energize and lock out the motor control circuit before removing or installing heater elements. Verify that the replacement heater suffix corresponds to the full-load amperage of the motor being protected before inserting the element. Do not modify the heater element or use it outside of its rated relay assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.419 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions (L x W x H)\u003c\/strong\u003e: 0.154 x 0.154 x 0.154 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 75455425927\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeater Class\u003c\/strong\u003e: SMF\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: SMFH09\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383893885234,"sku":"SMFH09","price":55.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312678940.jpg?v=1782610906","url":"https:\/\/voomisupply.com\/products\/siemens-smfh09-class-smf-heater-thermal-unit","provider":"Voomi Supply","version":"1.0","type":"link"}
