This fast-acting, current-limiting fuse is rated for up to 300VAC and 125VDC, with an interrupting capacity of 200 kA at 300VAC and 20 kA at 125VDC. The JLLN1200 is non-indicating and is designed for mounting in a compatible fuse block, clip, or holder, with the LSCR Series identified by Littelfuse as the PG holder. It's a focused electrical component built to last when correctly selected, installed, and operated within its specified ratings.\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: Clearly specified for applications requiring a 1200-amp Class T fuse.\u003c\/li\u003e\n\u003cli\u003eFast-acting operation: The JLLN1200 carries Littelfuse's Fast-Acting (F) opening designation, making this characteristic easy to verify during fuse selection.\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting design: Identified as part of Littelfuse's current-limiting fuse family.\u003c\/li\u003e\n\u003cli\u003eClass T configuration: Provides a defined fuse classification to match equipment requirements.\u003c\/li\u003e\n\u003cli\u003e300VAC maximum voltage: Rated for AC applications up to the manufacturer's specified 300VAC maximum.\u003c\/li\u003e\n\u003cli\u003e125VDC maximum voltage: Carries a separate maximum DC rating of 125VDC.\u003c\/li\u003e\n\u003cli\u003eKnife-blade\/bolt-in construction: Provides maintenance personnel and buyers with a key physical characteristic to confirm compatibility.\u003c\/li\u003e\n\u003cli\u003eNon-indicating fuse: Manufacturer data specifies that the JLLN1200 does not include an indicating function.\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 JLLN1200\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 Title:\u003c\/strong\u003e FUS 300V 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 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\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\u003ePG Holder:\u003c\/strong\u003e LSCR 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 specifications provided for the JLLN1200 did not include specific UL, CSA, CE, RoHS, REACH, or other certification or material-compliance information.
