The Eaton Bussmann KTU-4000 is rated at 4000A and 600V, with a manufacturer-listed interrupt rating of 200 kAIC at 600 Vac. Its physical configuration includes a bolted blade-end-to-bolted-blade-end connection and bolt mounting, giving maintenance teams two key details to compare with the existing equipment. The manufacturer lists silver-plated end bells and a melamine glass tube as the construction materials, along with a ferrule design as the special feature.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e4000A amperage rating — A key specification to confirm when matching the KTU-4000 against equipment requirements.\u003c\/li\u003e\n\u003cli\u003e600V voltage rating — Clearly identifies the manufacturer-listed voltage rating for this Class L fuse.\u003c\/li\u003e\n\u003cli\u003eClass L classification — Helps narrow replacement selection when equipment documentation specifically calls for a Class L fuse.\u003c\/li\u003e\n\u003cli\u003eBolted blade-end x bolted blade-end connection — Provides an exact connection specification that can be checked against the existing installation.\u003c\/li\u003e\n\u003cli\u003eFerrule design — The manufacturer lists this as the KTU-4000's special feature.\u003c\/li\u003e\n\u003cli\u003eNon-indicating fuse — The fuse indicator for this model is listed as non-indicating.\u003c\/li\u003e\n\u003cli\u003eCE Marked and RoHS Compliant — Supplies documented compliance information for applications where these requirements need to be confirmed.\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\u003eProduct Name:\u003c\/strong\u003e Eaton Bussmann series KTU fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e KTU-4000\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 051712613408\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEAN:\u003c\/strong\u003e 5027590446808\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e 4000 A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 600 V\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupt Rating:\u003c\/strong\u003e 200 kAIC at 600 Vac\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass:\u003c\/strong\u003e Class L\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e Bolted blade end x bolted blade end\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Indicator:\u003c\/strong\u003e Non-indicating\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Method:\u003c\/strong\u003e Bolt\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecial Features:\u003c\/strong\u003e Ferrule design\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Silver-plated end bells; melamine glass tube\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Length\/Depth:\u003c\/strong\u003e 7 in\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Height:\u003c\/strong\u003e 11 in\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Width:\u003c\/strong\u003e 7 in\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Weight:\u003c\/strong\u003e 21 lb\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompliances:\u003c\/strong\u003e CE Marked; RoHS Compliant\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 Eaton Bussmann KTU-4000 is CE Marked and RoHS compliant per the supplied manufacturer specifications.
