The Littelfuse JLLN450 brings together a specific set of characteristics: a 450A continuous current rating, Class T configuration, fast-acting opening, current-limiting design, and knife-blade\/bolt-in construction. For maintenance or replacement applications that require these exact characteristics, the JLLN450 provides a straightforward specification set to verify before installation. It's a focused electrical component built to last when properly selected, installed, and operated within its stated ratings.\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: Provides a precise amperage specification to compare with equipment requirements.\u003c\/li\u003e\n\u003cli\u003eClass T configuration: Clearly identifies the fuse class for easier compatibility checking.\u003c\/li\u003e\n\u003cli\u003eFast-acting (F): Littelfuse specifies the JLLN450 with a fast-acting opening characteristic.\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting design: The manufacturer identifies Current Limiting as the fuse's family style.\u003c\/li\u003e\n\u003cli\u003e300VAC maximum rating: Supports applications requiring this specified AC voltage rating, subject to the equipment requirements.\u003c\/li\u003e\n\u003cli\u003e125VDC maximum rating: Provides a separately defined DC voltage rating for compatible DC applications.\u003c\/li\u003e\n\u003cli\u003eKnife-blade\/bolt-in construction: Provides another important physical characteristic to check when confirming fit and compatibility.\u003c\/li\u003e\n\u003cli\u003eNon-indicating design: The manufacturer specifies the JLLN450 as non-indicating.\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\u003eManufacturer:\u003c\/strong\u003e Littelfuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e JLLN450\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e JLLN\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Description:\u003c\/strong\u003e FUS 300V F\/A CLASS T 450A\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\u003eFuse Class:\u003c\/strong\u003e Class T\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\u003eFamily Style:\u003c\/strong\u003e Current Limiting\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum AC Voltage:\u003c\/strong\u003e 300VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum DC Voltage:\u003c\/strong\u003e 125VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Interrupting Rating:\u003c\/strong\u003e 200,000A (200 kA) at 300VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupting Rating:\u003c\/strong\u003e 20,000A (20 kA) at 125VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize \/ Construction:\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\u003ePG Holder:\u003c\/strong\u003e LFT30600 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 manufacturer information supplied for the JLLN450 did not include specific UL, CSA, CE, RoHS, REACH, or other material-compliance or certification information.
