It features a ceramic tube body with nickel-plated brass end caps, measuring 0.25 inches in diameter by 1.25 inches in length. Time-delay fuses of this type are designed to withstand brief inrush currents without nuisance tripping while still providing reliable overcurrent protection for sustained fault conditions. Electricians and HVAC technicians install this fuse type in control circuits, small motors, and low-voltage equipment where momentary startup surges are expected.\u003c\/p\u003e\u003cp\u003eThis fuse is used in a wide range of residential and light commercial applications. Common installation scenarios include HVAC control boards, transformer secondaries, and small appliance protection circuits. The 30-amp, 250-volt rating makes it suitable for branch circuit protection in low-current applications where precise overcurrent coordination is required. Its compact cartridge form factor fits standard fuse holders and disconnect blocks designed for 0.25 by 1.25 inch glass or ceramic tube fuses.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTime-delay design tolerates motor inrush and startup surges without nuisance tripping\u003c\/li\u003e\n\u003cli\u003eCeramic tube construction for improved thermal stability compared to glass tube alternatives\u003c\/li\u003e\n\u003cli\u003eNickel-plated brass end caps for corrosion resistance and reliable contact conductivity\u003c\/li\u003e\n\u003cli\u003e30-amp, 250-volt rating suitable for low-current branch and control circuit protection\u003c\/li\u003e\n\u003cli\u003eCompact 0.25 by 1.25 inch cartridge form factor fits standard fuse holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement cartridge fuse for standard 0.25 by 1.25 inch fuse holders used in HVAC control circuits, transformer protection, and light commercial electrical equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis fuse should be installed by a licensed electrician or qualified HVAC technician in accordance with NEC requirements for overcurrent protection. Always disconnect and de-energize the circuit before replacing a fuse. Verify that the replacement fuse amperage and voltage ratings match the original equipment specification exactly. Do not substitute a higher-amperage fuse to address repeated tripping, as this can mask an underlying fault condition.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 30 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 250 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: Time Delay\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm Factor\u003c\/strong\u003e: Cartridge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 0.25 inches diameter x 1.25 inches length\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Cap Material\u003c\/strong\u003e: Nickel-plated brass\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BUSSMANN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MDA30\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BUSSMANN","offers":[{"title":"Default Title","offer_id":68093236248882,"sku":"MDA30","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e6977fd4d796f913d87672bc4a3b497.jpg?v=1793233567","url":"https:\/\/voomisupply.com\/products\/bussmann-mda30-time-delay-fuse-30a-250v-cartridge","provider":"Voomi Supply","version":"1.0","type":"link"}
