The Eaton Bussmann KTS-R-400 is a 400A Class RK1 fuse rated for 600V, with an interrupt rating of 200 kAIC at 600 Vac. Its physical construction includes a melamine glass tube, one element, and a blade-end-to-blade-end connection, while the manufacturer lists a knife blade as a special feature. Whether you're checking an existing KTS-R-400 or working from equipment documentation, having the electrical ratings, connection style, dimensions, and fuse class together makes the replacement comparison much more straightforward.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e400A rating — an essential specification to confirm when matching the fuse to equipment requirements.\u003c\/li\u003e\n\u003cli\u003e600V voltage rating clearly identifies the manufacturer's listed voltage specification.\u003c\/li\u003e\n\u003cli\u003eClass RK1 classification helps narrow the replacement search to the correct fuse class.\u003c\/li\u003e\n\u003cli\u003eBlade-end-to-blade-end connection provides a specific physical detail to compare with the existing installation.\u003c\/li\u003e\n\u003cli\u003eMelamine glass tube material is identified in the manufacturer specifications.\u003c\/li\u003e\n\u003cli\u003eSingle-element construction with one element listed.\u003c\/li\u003e\n\u003cli\u003eThe manufacturer identifies the knife blade as a special feature.\u003c\/li\u003e\n\u003cli\u003eThe fuse is listed as non-indicating.\u003c\/li\u003e\n\u003cli\u003eCE marked per the supplied compliance data.\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 KTS-R fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e KTS-R-400\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 051712417259\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 400 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 RK1\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Melamine glass tube\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Elements:\u003c\/strong\u003e 1\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e Blade end x 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\u003eSpecial Features:\u003c\/strong\u003e Knife blade\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Length\/Depth:\u003c\/strong\u003e 11.63 in\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Height:\u003c\/strong\u003e 2 in\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Width:\u003c\/strong\u003e 2 in\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Weight:\u003c\/strong\u003e 2.358 lb\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompliances:\u003c\/strong\u003e CE Marked\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 supplied manufacturer specifications list the KTS-R-400 as CE Marked and identify melamine glass tube as its material.
