Fuse links are thermal fusible elements that hold a damper blade in the open position under normal operating conditions. When ambient temperature rises to the rated threshold, the link melts and releases the blade, allowing the damper to close and restrict the spread of fire through ductwork. This component is a standard part of code-compliant life-safety damper systems and is installed by HVAC technicians and sheet metal mechanics during damper servicing or inspection cycles.\u003c\/p\u003e\u003cp\u003eThis fuse link is sized at 1.5 inches in length, making it suitable for damper applications that require this specific form factor. Fuse links must be replaced after any thermal activation or at intervals specified by the applicable fire and life-safety code. Replacement is a routine part of damper maintenance programs in both residential and commercial HVAC systems where fire-rated duct penetrations are present.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThermal fusible element rated for fire damper release applications\u003c\/li\u003e\n\u003cli\u003e1.5 inches in length for specific damper blade retention configurations\u003c\/li\u003e\n\u003cli\u003eSingle-use component replaced after thermal activation or scheduled maintenance\u003c\/li\u003e\n\u003cli\u003eSupports code-compliant fire damper operation in fire-rated duct assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement fuse link for fire damper assemblies requiring a 1.5-inch fusible link element.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eFuse link replacement is performed by qualified HVAC technicians or sheet metal mechanics during scheduled damper inspection or after a damper activation event. Shut down the air handling system and confirm zero airflow before accessing the damper assembly. Follow applicable codes including NFPA 80 and NFPA 90A for damper inspection and component replacement procedures. Never reuse a fuse link that has been thermally activated.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Type\u003c\/strong\u003e: Fuse Link\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LLOYD INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FL-B-NH\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LLOYD INDUSTRIES","offers":[{"title":"Default Title","offer_id":51284122042674,"sku":"FL-B-NH","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278373.jpg?v=1781069065","url":"https:\/\/voomisupply.com\/products\/lloyd-industries-fl-b-nh-fuse-link-1-5-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
