For AC applications, it is rated up to 300VAC with a 200 kA interrupting rating at 300VAC. On the DC side, it is rated up to 160VDC with a 50 kA interrupting rating at 160VDC. For maintenance, repair, or replacement work, this gives you several concrete specifications to check before installation rather than relying on appearance alone.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e20A continuous current rating — Gives you a clear amperage checkpoint when matching the fuse to equipment requirements.\u003c\/li\u003e\n\u003cli\u003eClass T configuration — Intended for equipment designed around the electrical and physical requirements of a Class T fuse.\u003c\/li\u003e\n\u003cli\u003eFast-acting (F) opening characteristic — Clearly identifies the manufacturer's specified opening behavior.\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting design — JLLN020 is identified as part of Littelfuse's current-limiting JLLN family.\u003c\/li\u003e\n\u003cli\u003eDual AC\/DC ratings — Rated for a maximum of 300VAC and 160VDC, making it important to match the rating to the actual circuit type.\u003c\/li\u003e\n\u003cli\u003eNon-indicating design — The manufacturer specifies the JLLN020 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 JLLN020\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\u003eProduct Type:\u003c\/strong\u003e Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current Rating:\u003c\/strong\u003e 20A\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\u003eAC Interrupting Rating:\u003c\/strong\u003e 200,000A (200 kA) at 300VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum DC Voltage:\u003c\/strong\u003e 160VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupting Rating:\u003c\/strong\u003e 50,000A (50 kA) at 160VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize \/ Construction:\u003c\/strong\u003e Industrial Cartridge\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 LFT30030 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 provided for the JLLN020 did not include specific UL, CSA, CE, RoHS, REACH, or other material-compliance or certification details.

For AC circuits, equipment requirements should align with its 300VAC maximum voltage and 200 kA interrupting rating at 300VAC. For DC applications, check against the separate 160VDC maximum voltage and 50 kA interrupting rating at 160VDC. The equipment must also accommodate the specified industrial cartridge construction and appropriate fuse block, clip, or holder arrangement.\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.
