The time-delay (TD) characteristic allows the fuse to withstand brief inrush currents without nuisance opening, while still providing reliable protection against sustained overloads and short circuits. This midget form factor fits standard 13\/32-inch x 1-1\/2-inch midget fuse holders commonly found in control panels, HVAC equipment, and light industrial applications. Each pack contains 10 fuses. Licensed electricians and HVAC technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis fuse is suited for residential and light commercial control circuits where low-amperage protection is required. Common applications include transformer secondary circuits, motor control panels, instrumentation, and HVAC control boards that require a midget fuse for branch-circuit or supplemental overcurrent protection. The time-delay design makes it appropriate for circuits with small motor loads or transformer inrush conditions where an instantaneous fuse would open unnecessarily.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e250-volt AC midget fuse with time-delay (TD) action for inrush tolerance\u003c\/li\u003e\n\u003cli\u003e4\/10 amp (0.4 amp) rating for low-amperage control circuit protection\u003c\/li\u003e\n\u003cli\u003eMidget form factor fits standard 13\/32-inch x 1-1\/2-inch fuse holders\u003c\/li\u003e\n\u003cli\u003eSold in a 10-pack for stocking convenience on service vehicles or in panel shops\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.13 pounds per pack for easy transport\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for midget time-delay fuses in residential and light commercial control panels and HVAC equipment requiring a 250-volt, 4\/10-amp supplemental or branch-circuit fuse.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician or qualified HVAC technician in accordance with NEC requirements for overcurrent protection. Always de-energize and lock out the circuit before replacing a fuse. Verify that the replacement fuse matches the voltage rating, amperage rating, and time-delay classification specified on the equipment nameplate or wiring diagram. Never substitute a higher-amperage or non-time-delay fuse in a circuit requiring the TD characteristic.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 250 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 4\/10 amp (0.4 amp)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: Midget Time-Delay (TD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions (L x W x H)\u003c\/strong\u003e: 1.62 inches x 0.88 inches x 2.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78200174309\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MERSEN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TRM4\/10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERSEN","offers":[{"title":"Default Title","offer_id":51383078388018,"sku":"TRM4\/10","price":38.13,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312675380.jpg?v=1782587428","url":"https:\/\/voomisupply.com\/products\/mersen-trm4-10-250v-midget-time-delay-fuse-10-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
