It measures 20 mm (approximately 0.787 inches) in overall length and 5 mm (approximately 0.197 inches) in diameter, fitting the standard midget fuse footprint used across control panels, instrumentation, and low-voltage equipment. The time delay characteristic allows the fuse to absorb brief inrush currents without nuisance opening, while still protecting the circuit from sustained overloads or short-circuit faults. Licensed electricians and service technicians commonly install this fuse in industrial controls, HVAC equipment, and precision instrumentation where reliable overcurrent protection is required.\u003c\/p\u003e\n\u003cp\u003eThis fuse is suited for use in residential, commercial, and light industrial equipment that calls for a 5 x 20 mm time delay cartridge fuse. Typical applications include transformer secondary circuits, motor control boards, HVAC control panels, and electronic instrumentation requiring low-amperage protection. Its glass body allows visual confirmation of fuse condition without removal, reducing diagnostic time during troubleshooting. The 0.25 A rating makes it appropriate for sensitive low-draw circuits where precision protection is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTime delay design absorbs inrush currents without nuisance tripping on motor or transformer starts\u003c\/li\u003e\n  \u003cli\u003eGlass body enables visual inspection for quick fault diagnosis in the field\u003c\/li\u003e\n  \u003cli\u003eInterrupting rating of 10,000 A at 125 volts and 35 A at 250 volts\u003c\/li\u003e\n  \u003cli\u003eMeets UL, CSA, PSE\/JET, and RoHS certifications for broad application compliance\u003c\/li\u003e\n  \u003cli\u003eStandard 5 x 20 mm cartridge form factor fits widely available panel fuse holders\u003c\/li\u003e\n  \u003cli\u003eLightweight at approximately 0.01 pounds for easy handling and inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for standard 5 x 20 mm time delay cartridge fuse positions in control panels, instrumentation enclosures, and HVAC equipment fuse holders rated for midget-style glass cartridge fuses.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified electrician or trained service technician. Always de-energize and lock out the circuit before replacing the fuse, following applicable NFPA 70 (NEC) lockout\/tagout procedures. Verify the replacement fuse amperage, voltage rating, and time delay classification match the original equipment specification before inserting. Do not use a higher-amperage fuse as a substitute, as this will defeat the overcurrent protection intended by the original circuit design.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 0.25 A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: Cartridge Time Delay (Mini)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 20 mm (approximately 0.787 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 5 mm (approximately 0.197 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Rating\u003c\/strong\u003e: 10,000 A at 125 volts; 35 A at 250 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Glass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: CSA Class 1422-01 File 53787; PSE\/JET File 1641-31003-1001; RoHS 2002\/95\/EC; UL Listed Guide JDYX File E19180; UL Recognized 4A Guide JDYX2 File E19180; UL\/CSA 248-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 39121605\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: GMD-250-R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51720181088562,"sku":"GMD-250-R","price":71.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64000d3b5e83edf62c8c9d7d47fc1025.jpg?v=1788561348","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-gmd-250-r-cartridge-time-delay-fuse-0-25a","provider":"Voomi Supply","version":"1.0","type":"link"}
