The KLLU750 is a 750-amp, current-limiting Class L fuse with a bolt-in design, a maximum rating of 600VAC and 300VDC, and time-delay operation intended to accommodate demanding startup conditions. If you're replacing an existing KLLU750, confirm the complete specification—not just 750A—including Class L construction, time-delay characteristics, AC\/DC ratings, interrupting capacity, and bolt-in mounting.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e750A continuous current rating for equipment specifically designed around a 750-amp Class L fuse.\u003c\/li\u003e\n\u003cli\u003eTime-delay opening characteristic helps accommodate temporary high-current conditions associated with large motor starting and other inductive loads.\u003c\/li\u003e\n\u003cli\u003eManufacturer specifies a minimum 10-second time delay at 500% of the rated current.\u003c\/li\u003e\n\u003cli\u003eRated for electrical systems up to 600VAC when all application requirements are met.\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting design helps reduce damage to systems and equipment during short-circuit conditions.\u003c\/li\u003e\n\u003cli\u003eThe manufacturer identifies motor branch-circuit protection as an appropriate KLLU Series application when the fuse is properly sized and applied.\u003c\/li\u003e\n\u003cli\u003eBolt-in construction provides a defined mounting configuration for equipment compatibility checks.\u003c\/li\u003e\n\u003cli\u003eNon-indicating configuration for applications calling for a standard non-indicating Class L 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 KLLU750\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Description:\u003c\/strong\u003e FUS 600V T\/D CLASS L 750A\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 750A\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\u003eSpecified Time Delay:\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 its time-delay Class L fuses meet or exceed UL requirements for Class L fuses.
