The Eaton Bussmann KTN-R-150 is a 150A Class RK1 fuse rated for 250 Vac and 250 Vdc, with separate interrupt ratings of 200 kAIC at 250 Vac and 100 kAIC at 250 Vdc. For electricians, plant maintenance teams, and electrical buyers, those details matter. Checking the KTN-R-150 catalog number, 150A rating, Class RK1 designation, AC\/DC voltage ratings, interrupt ratings, connection style, and dimensions gives you a much clearer picture of whether this is the specified replacement.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e150A Class RK1 fuse with clearly defined electrical ratings for straightforward specification matching.\u003c\/li\u003e\n\u003cli\u003eRated for both 250 Vac and 250 Vdc, giving technicians separate AC and DC application values to verify.\u003c\/li\u003e\n\u003cli\u003eThe blade-end-to-blade-end connection makes the physical connection style easy to compare with existing equipment.\u003c\/li\u003e\n\u003cli\u003eSingle-element construction adds another useful identification point during replacement work.\u003c\/li\u003e\n\u003cli\u003eMelamine glass tube is the manufacturer-listed fuse material.\u003c\/li\u003e\n\u003cli\u003e70\/30 brass end cap construction is specifically identified as a feature of the KTN-R-150.\u003c\/li\u003e\n\u003cli\u003eThe non-indicating design means this model does not include a built-in visual fuse-status indicator.\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 KTN-R Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e KTN-R-150\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 051712407182\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEAN:\u003c\/strong\u003e 5027590267458\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\u003eClass:\u003c\/strong\u003e Class RK1\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e 150 A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 250 Vac, 250 Vdc\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Interrupt Rating:\u003c\/strong\u003e 200 kAIC at 250 Vac\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupt Rating:\u003c\/strong\u003e 100 kAIC at 250 Vdc\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 Feature:\u003c\/strong\u003e 70\/30 brass end cap\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\/Depth:\u003c\/strong\u003e 7.1 in\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 1.56 in\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 1.56 in\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Weight:\u003c\/strong\u003e 0.92 lb\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\u003eFor the KTN-R-150, the supplied manufacturer specifications list compliance as \"Not Applicable.\" The provided product data states no additional material certifications or approval marks, so none are added or implied here.

Its blade-end configuration, single-element construction, and 7.1 x 1.56 x 1.56-inch dimensions give maintenance personnel several additional points to check before installation.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eA quick way to avoid mismatches is to work through the specification in order: start with KTN-R-150, confirm 150 amps and Class RK1, then check the 250V AC\/DC rating, applicable interrupt rating, blade-end connection, and physical dimensions. That takes only a moment, but it gives the buyer far more useful information than a product page that merely repeats a manufacturer data table.\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.
