It is a miniature fuse designed to protect low-current circuits by allowing brief inrush currents to pass without nuisance opening, while reliably clearing sustained overloads and fault conditions. The fuse measures 20 mm in overall length and 5 mm in diameter. Its ceramic body provides thermal stability and mechanical strength under fault conditions. Electricians and electronics service technicians install this fuse in control boards, instrumentation, and other low-voltage equipment where a mini cartridge fuse is specified.\u003c\/p\u003e\n\u003cp\u003eThis fuse is suited for residential and light commercial control circuit applications. It fits equipment and panel positions that accept a standard 5 mm x 20 mm mini cartridge fuse. Typical installations include HVAC control boards, power supplies, electronic instruments, and appliance protection circuits. The time delay characteristic makes it appropriate for circuits with motor start loads or transformer inrush where an instantaneous fuse would open unnecessarily.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6.3 amp rating with time delay (slow-blow) fuse timing for inrush tolerance\u003c\/li\u003e\n  \u003cli\u003eStandard 5 mm x 20 mm cartridge form factor for broad equipment compatibility\u003c\/li\u003e\n  \u003cli\u003eCeramic fuse body for high thermal stability and rupture containment\u003c\/li\u003e\n  \u003cli\u003eCarries multiple international certifications including IEC 60127-2, CSA, CCC, BSI, KC-Mark, and MQ listings\u003c\/li\u003e\n  \u003cli\u003eMiniature fuse type suited for low-current control and instrumentation circuits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct replacement for equipment requiring a 5 mm x 20 mm time delay cartridge fuse rated at 6.3 amps.

Always de-energize and lock out the equipment before replacing a fuse. Verify that the replacement fuse matches the original in amperage, time delay characteristic, and physical size. Never substitute a higher-amperage fuse or bypass the fuse holder.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 6.3 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Timing\u003c\/strong\u003e: Time Delay (Slow-Blow)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: Mini Cartridge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: IEC 60127-2, BSI File KM55676, CCC File 2002010207011295, CSA File 53787 Component Accepted, KC-Mark File SU05011-4012A, KC-Mark File SU05011-5004A, MQ File CA03.00100, MQ File CA03.00529, PES+JET File 1641-31003-1009\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 39121605\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: S505-6.3-R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51693880672562,"sku":"S505-6.3-R","price":135.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/af119666d3649aaaf363d83228dd65b7.jpg?v=1788318472","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-s505-6-3-r-time-delay-fuse-6-3a-ceramic","provider":"Voomi Supply","version":"1.0","type":"link"}
