There are a few specifications worth checking before you make the match. This 125A Class RK5 fuse is rated for 250V AC and 125V DC and uses a dual-element, blade-to-blade construction. Physically, the FRN-R-125 measures 2.1 inches long, 0.54 inches high, and 0.54 inches wide, so both its electrical ratings and blade-style configuration should be checked when replacing an existing fuse. In other words, if you're trying to identify the correct FRN-R-125, you have several concrete specifications to work with—not just the 125A rating printed on the fuse.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e125A Class RK5 fuse – Gives you a clearly defined amperage and fuse class to compare with the equipment specification.\u003c\/li\u003e\n\u003cli\u003e250V AC \/ 125V DC ratings – Covers properly specified AC and DC applications within the published voltage limits.\u003c\/li\u003e\n\u003cli\u003eDual-element construction – An important operating characteristic of the FRN-R-125 and one to confirm when selecting a replacement.\u003c\/li\u003e\n\u003cli\u003e10-second response at 500% – Gives technicians specific manufacturer-published response data rather than relying on assumptions about fuse behavior.\u003c\/li\u003e\n\u003cli\u003eBlade end × blade end connection – Makes the physical connection style straightforward to identify during maintenance or replacement.\u003c\/li\u003e\n\u003cli\u003eNon-indicating configuration – Matches equipment that specifies this particular fuse configuration.\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\n\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 FRN-R-125\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\u003eSeries:\u003c\/strong\u003e FRN-R\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class:\u003c\/strong\u003e Class RK5\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e 125A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Voltage Rating:\u003c\/strong\u003e 250V AC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Voltage Rating:\u003c\/strong\u003e 125V DC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Interrupting Rating:\u003c\/strong\u003e 200 kAIC at 250V AC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupting Rating:\u003c\/strong\u003e 20 kAIC at 125V DC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResponse Time:\u003c\/strong\u003e 10 seconds at 500% of rated current\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Elements:\u003c\/strong\u003e Dual\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e Blade end × 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\u003eLength \/ Depth:\u003c\/strong\u003e 2.1 in\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 0.54 in\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 0.54 in\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Weight:\u003c\/strong\u003e 0.5 lb\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging Type:\u003c\/strong\u003e Standard\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 051712507455\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 specifications identify the FRN-R-125 as CE Marked.
