The KLLU650 is a current-limiting, bolt-in fuse rated for up to 600VAC and 300VDC, with an AC interrupting rating of 200,000A at 600VAC and a DC interrupting rating of 20,000A at 300VDC. The current-limiting design reduces short-circuit damage to electrical systems and equipment, while the defined Class L, bolt-in configuration gives maintenance teams clear electrical and physical requirements to verify during replacement. The manufacturer also identifies the KLLU Series as UL Listed and states that it meets or exceeds UL requirements for Class L fuses.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e650A continuous current rating for equipment specifically designed around a 650-amp Class L fuse.\u003c\/li\u003e\n\u003cli\u003eTime-delay opening characteristic helps accommodate temporary high current associated with equipment startup.\u003c\/li\u003e\n\u003cli\u003eThe manufacturer specifies a minimum 10-second time delay at 500% of rated current, which is particularly useful with large motors and other inductive loads.\u003c\/li\u003e\n\u003cli\u003eThe current-limiting design reduces short-circuit damage to electrical systems and equipment.\u003c\/li\u003e\n\u003cli\u003eRated for applications up to 600VAC when all other system requirements are satisfied.\u003c\/li\u003e\n\u003cli\u003eAlso rated up to 300VDC, providing flexibility where the specified DC ratings match the application.\u003c\/li\u003e\n\u003cli\u003eBolt-in construction provides a defined mounting format that can be checked directly against the existing equipment.\u003c\/li\u003e\n\u003cli\u003eNon-indicating design for installations requiring 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 KLLU650\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Description:\u003c\/strong\u003e FUS 600V T\/D CLASS L 650A\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 650A\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 these time-delay Class L fuses meet or exceed UL requirements for Class L fuses.

The manufacturer identifies motor branch-circuit protection as an application for the KLLU Series and states that these fuses may be sized close to motor full-load current when properly applied. That makes the specified time-delay behavior particularly relevant around large motors and other inductive loads, where heavy starting current can occur during normal operation.\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.
