Built with a glass body measuring 1.25 inches in length and 0.25 inches in diameter, it is designed for SFE-series fuse holders commonly found in automotive and light vehicle electrical circuits. The fast-acting response characteristic means it clears overloads and short circuits quickly, protecting wiring harnesses, accessories, and control circuits from sustained fault current. It meets SAE standards and carries UL listing under Guide FHXT, File AU169, making it a recognized replacement option for service and fleet maintenance work.\u003c\/p\u003e\n\u003cp\u003eThis fuse is intended for low-voltage automotive circuits operating at 32 volts or below. Typical applications include underhood accessory circuits, instrument panel fuse blocks, and auxiliary circuit protection in passenger vehicles, light trucks, and similar equipment. Automotive technicians and fleet service professionals install this fuse type during routine electrical diagnosis, circuit repair, and preventive maintenance. Cross-reference part numbers Littlefuse 307020 and Ferraz Shawmut FSFE20 are noted in the product data as equivalent replacements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFast-acting fuse element clears overcurrent conditions rapidly to protect automotive wiring\u003c\/li\u003e\n  \u003cli\u003eGlass body construction allows visual inspection of the fuse element without removal\u003c\/li\u003e\n  \u003cli\u003eRated 20 amps at 32 volts AC\/DC for low-voltage automotive circuit protection\u003c\/li\u003e\n  \u003cli\u003eMeets SAE standards and is UL Listed under Guide FHXT, File AU169\u003c\/li\u003e\n  \u003cli\u003eSFE series form factor fits standard SFE-style automotive fuse holders\u003c\/li\u003e\n  \u003cli\u003eCross-references to Littlefuse 307020 and Ferraz Shawmut FSFE20\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe COOPER BUSSMANN SFE-20 is designed for use in SFE-series automotive fuse holders rated for circuits up to 32 volts AC\/DC.

Always replace a fuse with one of the same amperage and voltage rating. Never substitute a higher-amperage fuse to resolve a repeated blowing condition without first diagnosing the underlying fault. Refer to the vehicle manufacturer wiring diagram and applicable SAE or OEM service procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 20 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 32 volts AC\/DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Style\u003c\/strong\u003e: Fast Acting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SFE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Glass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Automotive Circuits\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUL Listed\u003c\/strong\u003e: Guide FHXT, File AU169\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: COOPER BUSSMANN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SFE-20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51716551213362,"sku":"SFE-20","price":22.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/433f7496ffea5044542406dedcaf88d8.jpg?v=1788527716","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-sfe-20-fast-acting-automotive-fuse-20a","provider":"Voomi Supply","version":"1.0","type":"link"}
