The KLLU1500 is a 1500-amp, time-delay, current-limiting Class L fuse built in a bolt-in configuration for equipment designed around these specific electrical and physical requirements. At the same time, its current-limiting design is intended to reduce short-circuit damage to systems and equipment. The manufacturer identifies the KLLU Series as UL Listed and states that it meets or exceeds UL requirements for Class L fuses. For replacement work, confirm the complete specification—1500A rating, Class L, time-delay operation, voltage, interrupting capacity, and bolt-in mounting—rather than choosing a fuse on amperage alone.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1500A continuous current rating for equipment specifically designed to use a 1500-amp Class L fuse.\u003c\/li\u003e\n\u003cli\u003eClass L fuse design provides a defined electrical and physical configuration for accurate replacement matching.\u003c\/li\u003e\n\u003cli\u003eTime-delay opening characteristic helps the fuse tolerate temporary high-current conditions associated with startup and inductive loads.\u003c\/li\u003e\n\u003cli\u003eThe KLLU Series provides a minimum 10-second time delay at 500% of rated current, helping avoid unnecessary fuse operation during heavy starting currents.\u003c\/li\u003e\n\u003cli\u003e600VAC maximum AC voltage gives technicians a clear voltage specification to compare with system requirements.\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting operation reduces short-circuit damage to systems and connected equipment.\u003c\/li\u003e\n\u003cli\u003eBolt-in construction and mounting make physical compatibility easy to specify and verify.\u003c\/li\u003e\n\u003cli\u003eConfirm the non-indicating configuration when matching the KLLU1500 to existing equipment.\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 KLLU1500\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Description:\u003c\/strong\u003e FUS 600V T\/D CLASS L 1500A\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 1500A\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 the series meets or exceeds UL requirements for Class L fuses.
