Measuring 1.25 inches in overall length and 0.25 inches in diameter, this mini-form-factor fuse carries an interrupting rating of 10,000 amps at 125 volts and 1,500 amps at 250 volts. The ceramic body provides superior heat resistance and arc containment compared to glass-body alternatives, making it a reliable choice for demanding service environments.\u003c\/p\u003e\u003cp\u003eThis fuse is suited for residential and light commercial applications including HVAC control boards, small motor circuits, power supplies, and test equipment. The time delay characteristic allows the fuse to tolerate brief inrush or startup surge currents without opening, while still responding quickly to sustained overloads. Electricians and HVAC technicians commonly use this fuse type when protecting sensitive low-amperage circuits that require a Class midget or mini fuse format.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e30-amp time delay rating handles startup inrush without nuisance opening\u003c\/li\u003e\n\u003cli\u003eCeramic fuse body provides strong arc containment and thermal stability\u003c\/li\u003e\n\u003cli\u003e10,000-amp interrupting rating at 125 volts for reliable fault protection\u003c\/li\u003e\n\u003cli\u003eMini cartridge form factor at 1.25 inches OAL and 0.25 inches diameter\u003c\/li\u003e\n\u003cli\u003eRoHS compliant and UL Recognized under Guide JDYX2 File E19180\u003c\/li\u003e\n\u003cli\u003eCSA Class No. 1422 30 Component Accepted and MIL-STD-202 Method 204 compliant\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for mini cartridge time delay fuse positions requiring a 30-amp, 0.25-inch diameter, 1.25-inch overall length fuse in 125-volt or 250-volt rated circuits.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician or qualified HVAC technician. Always de-energize the circuit and verify zero voltage with a meter before removing or installing any fuse. Use the correct fuse puller tool to avoid damage to the fuse holder contacts. Verify that the replacement fuse amperage and interrupting rating match or exceed the original equipment specification before energizing the circuit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 30 amps\u003c\/li\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\u003eInterrupting Rating\u003c\/strong\u003e: 10,000 amps at 125 volts; 1,500 amps at 250 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.25 inches (31.75 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 0.25 inches (6.35 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: CSA Class No. 1422 30 Component Accepted; MIL-STD-202 Method 204; UL Recognized Guide JDYX2 File E19180; RoHS Compliant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 39121605\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: MDA-30-R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51705668895026,"sku":"MDA-30-R","price":53.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30613c675437119db85654ede52b6a74.jpg?v=1788430368","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-mda-30-r-cartridge-time-delay-fuse-30a","provider":"Voomi Supply","version":"1.0","type":"link"}
