It features a dual-element design that tolerates brief motor-start inrush currents without nuisance opening, while still providing fast response to sustained overloads and short-circuit events. The cartridge form factor measures 13\/16 inch in diameter and 2-1\/4 inches in length. With an AC interrupting rating of 200,000 amps RMS symmetrical, this fuse is suited for branch circuit protection in commercial and industrial power distribution panels. Electricians and panel technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe JTD015 is used in commercial and industrial electrical systems where Class J fuse holders are specified. Typical applications include motor branch circuit protection, transformer primary protection, and panel feeder circuits requiring high interrupting capacity. The time delay characteristic makes it well suited for loads with high startup currents, including HVAC compressors, pumps, and other inductive motor loads. It is also cross-referenced under alternate identifiers LFUJTD15 and LFUJTD015.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDual-element time delay design tolerates motor inrush without nuisance tripping\u003c\/li\u003e\n  \u003cli\u003e200,000 amp AC RMS symmetrical interrupting rating for high-fault-current environments\u003c\/li\u003e\n  \u003cli\u003eRated 600 VAC and 300 VDC for versatile circuit protection\u003c\/li\u003e\n  \u003cli\u003eCartridge mounting fits standard Class J fuse holders\u003c\/li\u003e\n  \u003cli\u003eStone sand and granular quartz filler construction for arc suppression\u003c\/li\u003e\n  \u003cli\u003eCompact 13\/16 inch diameter by 2-1\/4 inch length cartridge form factor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for Class J cartridge fuse positions rated at 15 amps and 600 VAC in commercial and industrial power distribution equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a qualified electrician in accordance with NEC Article 240 and applicable local codes. Always de-energize and lock out the circuit before replacing any fuse. Use an appropriately rated fuse puller for cartridge fuse removal and confirm the replacement fuse matches the circuit voltage and ampere rating before re-energizing. Never substitute a fuse with a higher ampere rating than the circuit is designed for.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmpere Rating\u003c\/strong\u003e: 15 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating AC\u003c\/strong\u003e: 600 VAC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating DC\u003c\/strong\u003e: 300 VDC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: Class J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: Time Delay Dual Element\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Rating AC\u003c\/strong\u003e: 200,000 amps RMS symmetrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTerminal Type\u003c\/strong\u003e: Cartridge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stone sand and granular quartz filler\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: LITTELFUSE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JTD015\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LITTELFUSE","offers":[{"title":"Default Title","offer_id":67589814649138,"sku":"JTD015","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/177905073.jpg?v=1790419821","url":"https:\/\/voomisupply.com\/products\/littelfuse-jtd015-class-j-time-delay-fuse-15a-600vac","provider":"Voomi Supply","version":"1.0","type":"link"}
