The Littelfuse JLLS1200 combines a 1200A continuous current rating with fast-acting operation, current-limiting characteristics, and a Knife-Blade\/Bolt-In configuration. Built to last, its clearly defined Class T designation, electrical ratings, opening characteristic, and physical format make it easier to determine whether this is the correct fuse for your equipment—not simply one that happens to share the same amperage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1200A continuous current rating: Provides a clearly defined amperage specification for equipment requiring a 1200-amp fuse.\u003c\/li\u003e\n\u003cli\u003eClass T fuse: The fuse class provides an essential compatibility checkpoint when identifying a replacement or matching equipment requirements.\u003c\/li\u003e\n\u003cli\u003eFast-acting opening: Littelfuse identifies the JLLS1200 as Fast-Acting (F), so there is no need to guess about its opening characteristic.\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting design: Manufacturer specifications place the JLLS1200 in the current-limiting family.\u003c\/li\u003e\n\u003cli\u003eKnife-blade-style construction: Provides an important physical detail for matching the fuse with compatible equipment.\u003c\/li\u003e\n\u003cli\u003eKnife-Blade\/Bolt-In configuration: Helps narrow compatibility beyond catalog number and amperage alone.\u003c\/li\u003e\n\u003cli\u003eNon-indicating: Littelfuse specifies the JLLS1200 as a non-indicating fuse.\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 JLLS1200\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\u003eManufacturer Description:\u003c\/strong\u003e FUS 600V F\/A CLASS T 1200A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current Rating:\u003c\/strong\u003e 1200A\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 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 200,000A (200 kA) at 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupting Rating:\u003c\/strong\u003e 20,000A (20 kA) at 300VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Knife-blade style\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\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\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial Compliance and Certifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe supplied manufacturer specifications do not identify specific UL, CSA, CE, RoHS, REACH, or other certification or material-compliance information for the JLLS1200.
