The FLSR600-ID combines several important specifications in a single fuse: 600A continuous current, Class RK5 construction, time-delay operation, an indicating design, and ratings up to 600V AC and 300V DC. Its dual-element Slo-Blo \/ Time Lag (T) characteristic allows appropriate short-duration startup or inrush current without unnecessary opening, within the fuse’s specified operating characteristics.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e600A continuous rating – Built for applications specifically requiring a 600-amp fuse.\u003c\/li\u003e\n\u003cli\u003eClass RK5 configuration – Gives electricians and maintenance teams a clear fuse classification to match against equipment requirements.\u003c\/li\u003e\n\u003cli\u003eTime-delay performance – The Slo-Blo \/ Time Lag (T) characteristic accommodates appropriate temporary startup and inrush current within the fuse’s specified operating characteristics.\u003c\/li\u003e\n\u003cli\u003eIndicating design – A particularly useful feature during maintenance and troubleshooting, and an important detail when matching an existing fuse.\u003c\/li\u003e\n\u003cli\u003eDual-element construction – Part of the FLSR600-ID’s time-delay fuse design.\u003c\/li\u003e\n\u003cli\u003eKnife-blade style – Made for installation in compatible fuse blocks, clips, and holders.\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 FLSR600-ID\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Reference:\u003c\/strong\u003e FLSR600ID\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e FLSR_ID\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Dual-Element Time-Delay Fuse\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\u003eContinuous Current Rating:\u003c\/strong\u003e 600A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum AC Voltage:\u003c\/strong\u003e 600V AC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum DC Voltage:\u003c\/strong\u003e 300V DC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpening Characteristic:\u003c\/strong\u003e Slo-Blo \/ Time Lag (T) \/ Time Delay\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction \/ Size:\u003c\/strong\u003e Knife-Blade\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\u003eDC Interrupting Rating:\u003c\/strong\u003e 20 kA at 300V DC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer-Listed AC Interrupt Amperage:\u003c\/strong\u003e 200,000A and 300,000A at 600V AC*\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Method:\u003c\/strong\u003e Fuse Block \/ Clip \/ Holder\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePG Holder:\u003c\/strong\u003e LFR60600 Series\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 this particular fuse, the supplied manufacturer information confirms the Class RK5 classification but does not provide catalog-specific details on UL, CSA, RoHS, or other compliance standards.\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe FLSR600-ID makes sense when the equipment specification calls for a 600A Class RK5 time-delay fuse with knife-blade construction and an indicating configuration.
