The time-delay characteristic allows the fuse to ride through brief inrush currents common in motor-start and transformer applications without nuisance blowing, while still providing reliable short-circuit protection. Sold in a 10-pack, this midget fuse fits standard 13\/32-inch x 1-1\/2-inch midget fuse holders found throughout HVAC control panels, process equipment, and electrical enclosures. Licensed electricians and HVAC technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis fuse is commonly used in residential and light commercial HVAC systems, motor control centers, and industrial control panels where low-amperage overcurrent protection is required in a compact form factor. Typical applications include transformer secondary circuits, control circuit protection, and small fractional-horsepower motor branch circuits where a standard full-size fuse block is not practical or space-appropriate.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTime-delay design accommodates motor inrush and transformer energizing currents without nuisance opens\u003c\/li\u003e\n\u003cli\u003e250-volt rating covers standard single-phase control circuit applications\u003c\/li\u003e\n\u003cli\u003e3.5-amp current rating for low-amperage branch and control circuit protection\u003c\/li\u003e\n\u003cli\u003eMidget form factor fits 13\/32-inch x 1-1\/2-inch fuse holders standard in HVAC and industrial panels\u003c\/li\u003e\n\u003cli\u003eSold as a 10-pack for stocking and service-call convenience\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement midget time-delay fuse for use in standard 13\/32-inch x 1-1\/2-inch midget fuse holders in HVAC control panels, motor control circuits, and electrical enclosures rated for 250 volts or less at 3.5 amps or less.\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 NFPA 70 (NEC) requirements for overcurrent protection. Always de-energize the circuit and verify the absence of voltage with a meter before replacing a fuse. Confirm that the replacement fuse matches the circuit voltage rating and amperage exactly — never substitute a higher-rated fuse. Fuse holders should be inspected for damage, corrosion, or loose contacts during each replacement service.\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\u003eCurrent Rating\u003c\/strong\u003e: 3.5 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: Midget Time-Delay\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (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\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78200174339\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: TRM3-1\/2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERSEN","offers":[{"title":"Default Title","offer_id":51383063249202,"sku":"TRM3-1\/2","price":28.98,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312675424.jpg?v=1782587046","url":"https:\/\/voomisupply.com\/products\/mersen-trm3-1-2-midget-time-delay-fuse-3-5a-250v","provider":"Voomi Supply","version":"1.0","type":"link"}
