The time delay characteristic allows brief inrush currents to pass without nuisance tripping while still protecting downstream components from sustained overloads and short circuits. At 20 mm in overall length and 5 mm in diameter, this is a standard IEC mini fuse body size commonly found in HVAC control boards, instrumentation panels, and light commercial equipment. Licensed electricians and controls technicians are the typical installers for this component.\u003c\/p\u003e\n\u003cp\u003eThis fuse is suited for residential and light commercial applications where compact IEC-format fuse holders are specified. Typical installations include HVAC control circuit boards, low-voltage transformer secondary protection, electronic test instruments, and industrial control panels operating at 125 volts or 250 volts AC. The glass body allows visual inspection of the fuse element without removal, which speeds up diagnostic work in the field.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTime delay design tolerates inrush current without nuisance tripping\u003c\/li\u003e\n  \u003cli\u003eGlass body enables visual fuse element inspection without removal\u003c\/li\u003e\n  \u003cli\u003e10,000 amp interrupting rating at 125 volts for robust short-circuit protection\u003c\/li\u003e\n  \u003cli\u003e35 amp interrupting rating at 250 volts\u003c\/li\u003e\n  \u003cli\u003eIEC mini cartridge form factor: 20 mm overall length, 5 mm diameter\u003c\/li\u003e\n  \u003cli\u003eMulti-standard certified including UL Listed, CSA, PSE\/JET, and RoHS compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for IEC 20 mm x 5 mm mini cartridge time delay fuse holders used in HVAC controls, instrumentation, and light commercial electrical panels.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDe-energize and lock out the circuit before replacing any fuse. Verify replacement fuse amperage and time delay rating match the original specification exactly — substituting a fast-acting fuse in a time delay application or oversizing the amperage rating can damage equipment or create a fire hazard. Use an insulated fuse puller when removing or inserting fuses in live-adjacent holders. Installation must comply with applicable NEC requirements for overcurrent protection and equipment labeling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: Mini Cartridge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Timing\u003c\/strong\u003e: Time Delay\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 0.5 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Rating\u003c\/strong\u003e: 10,000 amps at 125 volts; 35 amps at 250 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.787 inches (20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 0.197 inches (5 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Glass\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: UL Listed Guide JDYX File E19180; UL Recognized 4A Guide JDYX2 File E19180; UL\/CSA 248-14; CSA Class 1422-01 File 53787; PSE\/JET File 1641-31003-1001; RoHS 2002\/95\/EC\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: GMD-500-R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51689140355378,"sku":"GMD-500-R","price":75.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa527148ef6f969b7f9b617b3a695119.jpg?v=1788255187","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-gmd-500-r-0-5a-time-delay-fuse","provider":"Voomi Supply","version":"1.0","type":"link"}
