The KLLU1000 is a 1000-amp, time-delay, current-limiting Class L fuse with a bolt-in design, rated for up to 600VAC and 300VDC. The manufacturer also identifies the KLLU Series as UL Listed and states that it meets or exceeds UL requirements for Class L fuses. If you're evaluating the KLLU1000 as a replacement, don't match on 1000A alone—confirm the Class L designation, voltage, interrupting ratings, time-delay characteristics, bolt-in configuration, and equipment requirements before selecting.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1000A continuous current rating for equipment designed around a 1000-amp Class L fuse\u003c\/li\u003e\n\u003cli\u003eClass L fuse design with manufacturer-stated compliance with applicable UL Class L requirements\u003c\/li\u003e\n\u003cli\u003eTime-delay operation helps accommodate temporary starting currents rather than treating every brief current increase the same way\u003c\/li\u003e\n\u003cli\u003eProvides a minimum 10-second time delay at 500% of rating, according to the manufacturer\u003c\/li\u003e\n\u003cli\u003e600VAC maximum voltage rating\u003c\/li\u003e\n\u003cli\u003e300VDC maximum voltage rating\u003c\/li\u003e\n\u003cli\u003eThe manufacturer specifies a current-limiting design to reduce short-circuit damage to systems and equipment\u003c\/li\u003e\n\u003cli\u003eManufacturer describes selective-coordination capabilities with other Class L fuses and compatible current-limiting fuses rated 600A or less\u003c\/li\u003e\n\u003cli\u003eBolt-in construction and mounting provide clear physical characteristics to check when matching an existing installation\u003c\/li\u003e\n\u003cli\u003eNon-indicating configuration should be verified when replacing an existing 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\u003eCatalog Number:\u003c\/strong\u003e KLLU1000\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Description:\u003c\/strong\u003e FUS 600V T\/D CLASS L 1000A\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 1000A\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\u003eTime-Delay Characteristic:\u003c\/strong\u003e Minimum 10 seconds at 500% of rating, as specified for the KLLU Series\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 all UL requirements for Class L fuses.

Its manufacturer-described time-delay behavior makes it particularly relevant where temporary starting currents are part of normal operation, including qualifying large-motor and other inductive-load applications. The manufacturer specifically states that KLLU fuses may be used for motor branch-circuit protection and that the time delay helps prevent unnecessary downtime caused by heavy motor starting currents.\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.
