The Littelfuse JLLN250 combines a 250A continuous current rating with fast-acting operation, a current-limiting design, and knife-blade\/bolt-in construction. When the application requires these exact specifications, the JLLN250 is a straightforward 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\u003e250A continuous current rating: Clearly defined for equipment requiring a 250-amp fuse.\u003c\/li\u003e\n\u003cli\u003eClass T configuration: Provides an important compatibility checkpoint when replacing or identifying an existing fuse.\u003c\/li\u003e\n\u003cli\u003eFast-acting opening: Littelfuse specifies the JLLN250 as Fast-Acting (F).\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting design: Gives you another manufacturer-defined characteristic to match against the application's requirements.\u003c\/li\u003e\n\u003cli\u003e300VAC maximum voltage: Rated for compatible AC applications up to 300 volts.\u003c\/li\u003e\n\u003cli\u003e125VDC maximum voltage: Also carries a defined DC rating up to 125 volts.\u003c\/li\u003e\n\u003cli\u003eKnife-blade\/bolt-in construction: Provides a distinct physical configuration that should match the equipment and mounting arrangement.\u003c\/li\u003e\n\u003cli\u003eNon-indicating design: The JLLN250 does not incorporate an indicating feature.\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 JLLN250\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 250A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current Rating:\u003c\/strong\u003e 250A\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 LFT30400 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 data supplied for the JLLN250 did not include specific UL, CSA, CE, RoHS, REACH, or other certification or material-compliance information.

It is particularly easy to evaluate when equipment documentation provides the required fuse class, amperage, voltage, interrupting capacity, and physical mounting information. For AC applications, the relevant specifications are 300VAC maximum and 200 kA interrupting capacity at 300VAC. For DC applications, they are 125VDC maximum and 20 kA interrupting capacity at 125VDC.\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cbr\u003e\n\u003cdiv\u003e\n\u003cblockquote\u003e\n\u003cp style=\"font-size: 12px;\"\u003e\u003cem\u003eUse of Original Equipment Manufacturer (OEM) trademarks, names, and logos is for informational and identification purposes only.
