This compact component protects motors and electrical equipment from sustained overcurrent conditions by responding to heat generated by excess current flow. It is installed inside a matching overload relay block, where it works as part of a thermal overload protection system. Electricians and industrial maintenance technicians typically handle this installation. The SMFH52 measures 0.311 x 0.154 x 0.154 inches and weighs approximately 0.044 pounds, making it a small but critical piece of motor protection hardware.\u003c\/p\u003e\n\u003cp\u003eThis heater element is suited for industrial and commercial electrical systems where motor overload protection is required. It fits into Siemens thermal overload relay assemblies that accept Class SMF heater elements. The SMFH52 is a direct-replacement component used when servicing motor starters and contactor assemblies in panels, motor control centers, and similar control equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass SMF heater element for Siemens thermal overload relay assemblies\u003c\/li\u003e\n  \u003cli\u003eProvides thermal overcurrent protection for motors and electrical loads\u003c\/li\u003e\n  \u003cli\u003eCompact form factor: 0.311 x 0.154 x 0.154 inches\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.044 pounds for easy handling during relay servicing\u003c\/li\u003e\n  \u003cli\u003eDirect OEM-style replacement for worn or failed heater elements\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 thermal overload relay assemblies that accept Class SMF heater elements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician familiar with motor control equipment and applicable NEC requirements. De-energize and lock out the motor control circuit before removing or replacing any overload relay components. Ensure the replacement heater element class and designation match the original before installation. Do not attempt to modify or adapt heater elements for use outside their rated relay assembly.\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\u003eDimensions (L x W x H)\u003c\/strong\u003e: 0.311 x 0.154 x 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: 75455425971\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: SMFH52\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383462592818,"sku":"SMFH52","price":51.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312675534.jpg?v=1782597356","url":"https:\/\/voomisupply.com\/products\/siemens-smfh52-class-smf-heater","provider":"Voomi Supply","version":"1.0","type":"link"}
