Class J fuses are current-limiting, meaning they interrupt fault currents rapidly to protect downstream equipment from damage. The time delay characteristic allows the fuse to ride through brief, harmless inrush currents — common during motor starts and transformer energizing — without nuisance opening. This fuse is installed by licensed electricians in industrial, commercial, and HVAC power distribution applications where equipment protection and NEC compliance are required.\u003c\/p\u003e\n\u003cp\u003eClass J time delay fuses like the LPJ-3-1\/2SP are used in motor branch circuits, control panels, disconnect switches, and combination starters where current-limiting overcurrent protection is specified. The 600-volt rating makes this fuse suitable for use in both 120-volt and 480-volt single-phase and three-phase systems commonly found in light commercial and industrial facilities. HVAC technicians also specify Class J fuses in equipment disconnect applications where the equipment nameplate calls for a time delay fuse of this ampere class.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass J current-limiting design provides fast fault interruption to protect sensitive equipment\u003c\/li\u003e\n  \u003cli\u003eTime delay element prevents nuisance opening during motor start inrush and transformer energizing\u003c\/li\u003e\n  \u003cli\u003e600-volt rating covers a wide range of single-phase and three-phase distribution circuits\u003c\/li\u003e\n  \u003cli\u003e3.5-amp rating suitable for small motor branch circuits and control circuit protection\u003c\/li\u003e\n  \u003cli\u003eClass J form factor is non-interchangeable with lower-rated fuse classes, preventing mis-installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement Class J time delay fuse for use in any UL-listed Class J fuse holder or fusible disconnect rated for 600 volts and the appropriate ampere range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC). Always de-energize and lock out the circuit before removing or installing fuses. Use a properly rated fuse puller when handling Class J fuses in energized equipment — never use pliers or uninsulated tools. Verify the replacement fuse ampere rating and voltage rating match the equipment nameplate before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmpere Rating\u003c\/strong\u003e: 3.5 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: Class J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResponse Type\u003c\/strong\u003e: Time Delay\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 05171252277\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: EATON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LPJ-3-1\/2SP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51383005151538,"sku":"LPJ-3-1\/2SP","price":97.74,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312677964.jpg?v=1782585194","url":"https:\/\/voomisupply.com\/products\/eaton-lpj-3-1-2sp-class-j-time-delay-fuse-3-5a-600v","provider":"Voomi Supply","version":"1.0","type":"link"}
