The KLLU3000 is a 3000-amp, Class L, time-delay, current-limiting fuse in a bolt-in configuration, rated for systems up to 600VAC or 300VDC. The manufacturer identifies the KLLU Series as UL Listed and meeting or exceeding UL requirements for Class L fuses. For a replacement or new application, confirm the complete electrical and physical specifications—not just the 3000A marking—to ensure the KLLU3000 matches the equipment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e3000A continuous current rating for equipment specifically designed around a 3000-amp Class L fuse.\u003c\/li\u003e\n\u003cli\u003eClass L configuration provides the defined fuse class needed for proper equipment and replacement matching.\u003c\/li\u003e\n\u003cli\u003eTime-delay operation accommodates temporary high-current conditions associated with startup.\u003c\/li\u003e\n\u003cli\u003eThe manufacturer specifies a minimum 10-second time delay at 500% of the fuse rating.\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting design helps reduce short-circuit damage to electrical systems and connected equipment.\u003c\/li\u003e\n\u003cli\u003eRated for operation up to 600VAC.\u003c\/li\u003e\n\u003cli\u003eAlso rated for applications up to 300VDC, when the equipment is designed to meet the fuse's full DC specifications.\u003c\/li\u003e\n\u003cli\u003eBolt-in construction and mounting provide a specific physical configuration that can be checked directly against the equipment.\u003c\/li\u003e\n\u003cli\u003eNon-indicating design for installations requiring this fuse configuration.\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\u003eCatalog Number:\u003c\/strong\u003e KLLU3000\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Description:\u003c\/strong\u003e FUS 600V T\/D CLASS L 3000A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e KLLU\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Time-Delay Current-Limiting Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current Rating:\u003c\/strong\u003e 3000A\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 at 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupting Rating:\u003c\/strong\u003e 20,000A at 300VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpening Characteristic:\u003c\/strong\u003e Slo-Blo \/ Time Lag (T) \/ Time Delay\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries Time-Delay Characteristic:\u003c\/strong\u003e Minimum 10 seconds at 500% of rated current\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class:\u003c\/strong\u003e Class L\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\u003eConstruction \/ Size:\u003c\/strong\u003e 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 Bolt-In\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 identifies the KLLU Series as UL Listed and states that KLLU Series fuses meet or exceed UL requirements for Class L fuses.

Its minimum 10-second time delay at 500% of rating is intended to accommodate the heavy starting currents encountered with large motors and other inductive loads. At the same time, its current-limiting characteristic is designed to reduce short-circuit damage.\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.
