The KLLU900 combines a 900A continuous current rating with Class L construction, current-limiting performance, and bolt-in mounting. Its current-limiting design is intended to reduce short-circuit damage to systems and equipment. For replacement or equipment-matching, confirm the full KLLU900 specification—including fuse class, voltage, interrupting capacity, time-delay characteristics, and bolt-in configuration—rather than selecting based on the 900A rating alone.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e900A continuous current rating for equipment specifically designed around a 900-amp Class L fuse.\u003c\/li\u003e\n\u003cli\u003eTime-delay operation helps accommodate temporary high starting currents associated with large motors and other inductive loads.\u003c\/li\u003e\n\u003cli\u003eManufacturer specifies a minimum 10-second time delay at 500% of the fuse rating.\u003c\/li\u003e\n\u003cli\u003e600VAC maximum voltage rating with a 200,000A interrupting rating at 600VAC.\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting design helps reduce short-circuit damage to electrical systems and equipment.\u003c\/li\u003e\n\u003cli\u003eManufacturer guidance specifically identifies motor branch-circuit protection as an application for properly selected KLLU fuses.\u003c\/li\u003e\n\u003cli\u003eBolt-in construction and mounting provide the physical format required by equipment designed for this type of Class L fuse.\u003c\/li\u003e\n\u003cli\u003eNon-indicating design for installations that specify a standard fuse without a visual indication feature.\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 KLLU900\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Description:\u003c\/strong\u003e FUS 600V T\/D CLASS L 900A\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 900A\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.

The manufacturer specifically describes KLLU fuses for motor branch-circuit protection, where properly selected fuses may be sized close to motor full-load current to protect branch-circuit conductors, motor control equipment, and motors. The specified minimum 10-second time delay at 500% of rating also makes this series relevant for large motors and other inductive loads that produce heavy 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.
