It is designed to protect electrical circuits in commercial vehicles and passenger cars from overcurrent faults. The green color coding allows for quick amp-rating identification during inspection or replacement. The housing is constructed from PA66-GF13 glass-filled nylon for durability in underhood and panel-mount environments. Automotive electricians and fleet maintenance technicians install this fuse in fuse boxes and PDCs where space-saving low-profile components are required.\u003c\/p\u003e\n\u003cp\u003eThis fuse fits commercial vehicle and passenger car applications where the LP JCASE form factor is specified. It is commonly installed in blade-type fuse holders and power distribution centers that accept low-profile JCASE fuses. The 40A rating covers mid-range circuit protection loads such as blower motors, accessory circuits, and relay-controlled loads. This part is sold individually with a minimum order quantity of 5 units, making it appropriate for shop stock and fleet service operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLow-profile JCASE blade design fits compact fuse holders and PDCs\u003c\/li\u003e\n  \u003cli\u003e40A rating at 58 VDC suits a wide range of mid-load automotive circuits\u003c\/li\u003e\n  \u003cli\u003eGreen color coding enables fast visual amp identification\u003c\/li\u003e\n  \u003cli\u003ePA66-GF13 glass-filled nylon housing resists heat and vibration in underhood environments\u003c\/li\u003e\n  \u003cli\u003eMeets ISO 8820-4, SAE 2741, and RoHS compliance standards\u003c\/li\u003e\n  \u003cli\u003eStandard blade style for broad fuse-holder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for commercial vehicle and passenger car electrical systems requiring an LP JCASE low-profile blade fuse at 40 amps and 58 VDC per ISO 8820-4 and SAE 2741 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified automotive or fleet electrician. Disconnect the vehicle battery before servicing any fuse panel or power distribution center to prevent arc faults and accidental circuit activation. Confirm the replacement fuse amp rating matches the circuit requirement exactly — never substitute a higher-rated fuse to address a repeatedly blown fuse condition. Diagnose the root overcurrent fault before installing the new fuse.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 40A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 58 VDC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Style\u003c\/strong\u003e: Low Profile JCASE (LP JCASE)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Style\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Green\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 14.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 16 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: PA66-GF13 (glass-filled nylon)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCover Material\u003c\/strong\u003e: PSU (polysulfone)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResistance\u003c\/strong\u003e: 1.89 milliohms\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Commercial Vehicle, Passenger Car\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 8820-4, SAE 2741, RoHS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: LJCA040.XP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LITTELFUSE","offers":[{"title":"Default Title","offer_id":51539490046258,"sku":"LJCA040.XP","price":32.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/879d9ab6ac4806f4211640fcf27e4172.jpg?v=1785841542","url":"https:\/\/voomisupply.com\/products\/littelfuse-ljca040-xp-low-profile-jcase-fuse-40a-58vdc","provider":"Voomi Supply","version":"1.0","type":"link"}
