This cartridge-style fuse is rated for 20 amps at 250 VAC and provides a 200 kA interrupting rating at 250 VAC. Its time-delay design is particularly useful in circuits where motors, transformers, and similar equipment can draw a brief current surge when starting. Instead of reacting to every momentary inrush, the fuse allows for these normal operating conditions while remaining ready to respond to sustained overloads and short circuits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e20A, 250 VAC rating for compatible commercial and industrial electrical applications.\u003c\/li\u003e\n\u003cli\u003eTime-delay performance accommodates brief inrush currents that can occur during normal equipment startup.\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting Class R design helps limit fault-current energy when the fuse operates.\u003c\/li\u003e\n\u003cli\u003eThe built-in indication helps maintenance personnel spot an open fuse more quickly.\u003c\/li\u003e\n\u003cli\u003eCartridge-style construction is suitable for equipment designed for this type and class of fuse.\u003c\/li\u003e\n\u003cli\u003eAt just 2.0 x 0.56 x 0.56 inches, its compact dimensions make it easy to check physical replacement requirements.\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\u003ePart Number:\u003c\/strong\u003e FLNR020-ID\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e FLNR\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class:\u003c\/strong\u003e Class R\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle:\u003c\/strong\u003e Cartridge\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 20 A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 250 VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA.I.C. \/ Interrupting Rating:\u003c\/strong\u003e 200 kA at 250 VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTime Delay:\u003c\/strong\u003e Yes\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Limiting:\u003c\/strong\u003e Yes\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndicating:\u003c\/strong\u003e Yes\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 2.0 in.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 0.56 in.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth:\u003c\/strong\u003e 0.56 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 FLNR020-ID is specified as a Class R, current-limiting fuse with a 200 kA interrupting rating at 250 VAC.
