With an interrupting rating of 100 kA at DC and 300 kA at AC (RMS), this fuse delivers high fault-current capacity in a compact cartridge body. It measures 2.25 inches in overall length and 20.60 mm in diameter, fitting standard Class J fuse holders. The time delay characteristic allows the fuse to tolerate brief inrush currents while still responding quickly to sustained overloads and short circuits. Licensed electricians and industrial maintenance technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis fuse is suited for residential, commercial, and light industrial electrical panels, motor control centers, and disconnect switches where Class J fuse holders are installed. The general-purpose rating makes it appropriate for branch circuit protection, control transformer protection, and equipment panels requiring a compact, high-interrupting-rated fuse. It is a non-indicating type, so visual confirmation of a blown fuse requires a continuity check or dedicated fuse tester rather than an integral flag indicator.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2.5 amp rating with time delay action to tolerate motor inrush and transformer magnetizing currents\u003c\/li\u003e\n  \u003cli\u003eHigh interrupting rating: 100 kA at DC and 300 kA at AC (RMS)\u003c\/li\u003e\n  \u003cli\u003eClass J form factor fits standard Class J fuse holders and disconnects\u003c\/li\u003e\n  \u003cli\u003eDual-element construction (2 elements) for accurate time delay response\u003c\/li\u003e\n  \u003cli\u003eNon-indicating body keeps installation profile low in tight panel spaces\u003c\/li\u003e\n  \u003cli\u003eUL Listed, CSA Certified, CE Certified, and RoHS Compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Class J fuse holders and fusible disconnect switches rated for Class J fuses.

De-energize and lockout\/tagout the circuit before removing or inserting any fuse. Confirm the fuse holder is rated for Class J fuses and that the holder contact clips are clean and undamaged before seating the fuse. Never substitute a fuse of a different class, higher amperage, or lower interrupting rating than what the circuit requires.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 2.5 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Timing\u003c\/strong\u003e: Time Delay\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Body Type\u003c\/strong\u003e: Cartridge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Elements\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Rating (AC RMS)\u003c\/strong\u003e: 300 kA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Rating (DC)\u003c\/strong\u003e: 100 kA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches (57.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 20.60 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Fuse Holder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndicating\u003c\/strong\u003e: Non-Indicating\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: UL Listed (Guide JDDZ, File E4273), CSA 22.2 No.248, CSA Class 1422-02 (File 53787), CE Certified, RoHS Compliant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 39121605\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: COOPER BUSSMANN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LPJ-2-1\/2SP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51689883042098,"sku":"LPJ-2-1\/2SP","price":734.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec938883328f3cfcc55dad4d55cae3f1.jpg?v=1788265084","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-lpj-2-1-2sp-class-j-fuse-2-5a","provider":"Voomi Supply","version":"1.0","type":"link"}
