The KLLU1400 is a 1400A Class L time-delay, current-limiting fuse with bolt-in mounting, a maximum rating of 600VAC \/ 300VDC, and high interrupting capacity for demanding electrical systems. The manufacturer also identifies the KLLU Series as UL Listed and states that it meets or exceeds UL requirements for Class L fuses. When you're matching a KLLU1400 replacement, check the complete specification—1400A rating, Class L configuration, time-delay characteristics, voltage, interrupting capacity, and bolt-in mounting—not amperage alone.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1400A continuous current rating for electrical equipment specifically designed around a 1400-amp Class L fuse.\u003c\/li\u003e\n\u003cli\u003eClass L configuration provides a clearly defined fuse class for accurate equipment and replacement matching.\u003c\/li\u003e\n\u003cli\u003eTime-delay operation helps accommodate temporary high-current conditions rather than responding unnecessarily to normal startup current.\u003c\/li\u003e\n\u003cli\u003eThe KLLU Series provides a minimum 10-second time delay at 500% of rated current, particularly useful where heavy motor starting or inductive-load currents are expected.\u003c\/li\u003e\n\u003cli\u003e600VAC maximum AC rating makes the voltage requirement straightforward to verify against the equipment.\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting performance is designed to reduce short-circuit damage to systems and equipment.\u003c\/li\u003e\n\u003cli\u003eBolt-in construction gives installers and maintenance teams an important physical characteristic to confirm before replacement.\u003c\/li\u003e\n\u003cli\u003eMatch the non-indicating design to the equipment configuration specified.\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 KLLU1400\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Description:\u003c\/strong\u003e FUS 600V T\/D CLASS L 1400A\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 Class L Time-Delay Current-Limiting Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current Rating:\u003c\/strong\u003e 1400A\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 these fuses meet or exceed UL requirements for Class L fuses.
