Rated for a maximum of 600VAC and 300VDC, the JLLS450 carries a 200 kA AC interrupting rating at 600VAC and a 20 kA DC interrupting rating at 300VDC. If you're replacing an existing JLLS450, the catalog number is a great starting point—but don't stop there. Before installation, check the 450A rating, voltage, Class T designation, interrupting capacity, opening characteristic, physical configuration, and equipment requirements. That extra verification matters with electrical protection components, where two fuses with the same amperage can have very different operating characteristics.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e450A continuous current rating for equipment designed around 450-amp fuse protection.\u003c\/li\u003e\n\u003cli\u003eHandles applications rated up to 600VAC.\u003c\/li\u003e\n\u003cli\u003eSupports properly specified DC applications up to 300VDC.\u003c\/li\u003e\n\u003cli\u003eFast-acting (F) opening characteristic operates without an intentional time delay.\u003c\/li\u003e\n\u003cli\u003eClass T current-limiting design provides the fuse style specified for this product.\u003c\/li\u003e\n\u003cli\u003eKnife-blade\/bolt-in construction provides the JLLS450's specified mechanical configuration.\u003c\/li\u003e\n\u003cli\u003eNon-indicating design without an integrated blown-fuse indicator.\u003c\/li\u003e\n\u003cli\u003eMounts using the appropriate fuse block, clip, or holder.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e JLLS450\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e JLLS\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Class T Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current Rating:\u003c\/strong\u003e 450A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum AC Voltage:\u003c\/strong\u003e 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum DC Voltage:\u003c\/strong\u003e 300VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Interrupting Rating:\u003c\/strong\u003e 200 kA at 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupting Rating:\u003c\/strong\u003e 20 kA at 300VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpening Characteristic:\u003c\/strong\u003e Fast-Acting (F)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class:\u003c\/strong\u003e Class T\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFamily Style:\u003c\/strong\u003e Current Limiting\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction \/ Size:\u003c\/strong\u003e Knife-Blade \/ Bolt-In\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndicating:\u003c\/strong\u003e No\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Method:\u003c\/strong\u003e Fuse Block \/ Clip \/ Holder\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecified Holder Series:\u003c\/strong\u003e LFT60600 Series\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial Compliance and Certifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe supplied product information identifies the JLLS450 as a Class T, fast-acting, current-limiting fuse and documents its primary electrical ratings, physical style, interrupting capacities, and mounting method.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe JLLS450 450A Class T fuse is best suited to electrical equipment specifically engineered around a 450A, fast-acting Class T fuse.
