The KLLU2500 is a 2500-amp Class L time-delay, current-limiting fuse with bolt-in construction, a maximum rating of 600VAC and 300VDC, and a 200,000A interrupting rating at 600VAC. The manufacturer identifies the KLLU Series as UL Listed and states that it meets or exceeds UL requirements for Class L fuses. If you're replacing an existing KLLU2500, don't stop at matching 2500A—confirm the Class L configuration, time-delay characteristic, voltage ratings, interrupting capacity, and bolt-in mounting against the equipment requirements.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e2500A continuous current rating for electrical equipment specifically designed to use a 2500-amp Class L fuse.\u003c\/li\u003e\n\u003cli\u003eClass L fuse configuration provides a clearly defined electrical and physical profile for replacement matching.\u003c\/li\u003e\n\u003cli\u003eTime-delay operation helps accommodate temporary high-current conditions associated with equipment startup.\u003c\/li\u003e\n\u003cli\u003eThe KLLU Series provides a minimum 10-second time delay at 500% of rated current, according to the manufacturer's specifications.\u003c\/li\u003e\n\u003cli\u003eThis delay is particularly useful around the heavy starting currents of large motors and other inductive loads.\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting design helps reduce short-circuit damage to systems and equipment.\u003c\/li\u003e\n\u003cli\u003eSupports electrical systems operating at up to 600VAC.\u003c\/li\u003e\n\u003cli\u003eBolt-in construction makes mounting style another straightforward specification to verify during replacement.\u003c\/li\u003e\n\u003cli\u003eThe non-indicating design matches applications that call for this 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 KLLU2500\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Description:\u003c\/strong\u003e FUS 600V T\/D CLASS L 2500A\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 2500A\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.
