This Class RK5 dual-element, time-delay fuse is rated for 600VAC and 300VDC and combines overload protection with high-capacity short-circuit protection. Because it has a time-delay opening characteristic, the FLSR040-ID can tolerate temporary inrush currents during normal equipment startup while still responding to an actual overload or fault. It also takes some of the guesswork out of maintenance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e40A continuous rating for circuits requiring 40-amp overcurrent protection.\u003c\/li\u003e\n\u003cli\u003eRated for applications up to 600VAC or 300VDC.\u003c\/li\u003e\n\u003cli\u003eClass RK5, dual-element construction combines time-delay operation with current-limiting protection.\u003c\/li\u003e\n\u003cli\u003eHandles normal, temporary inrush currents without opening unnecessarily.\u003c\/li\u003e\n\u003cli\u003eThe built-in blown-fuse indication makes it easier to spot an open fuse during troubleshooting.\u003c\/li\u003e\n\u003cli\u003eCartridge-style construction works with the appropriate fuse block, clip, or holder.\u003c\/li\u003e\n\u003cli\u003eA useful choice where reducing troubleshooting time and equipment downtime matters.\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 FLSR040-ID \/ FLSR040ID\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\u003eFuse 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\u003eCurrent Rating:\u003c\/strong\u003e 40A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum AC Voltage:\u003c\/strong\u003e 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum DC Voltage:\u003c\/strong\u003e 300VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpening Characteristic:\u003c\/strong\u003e Slo-Blo \/ Time Lag \/ Time Delay\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Interrupting Rating:\u003c\/strong\u003e 200,000A RMS symmetrical\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdditional AC Interrupting Rating:\u003c\/strong\u003e 300,000A RMS symmetrical, manufacturer self-certified\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupting Rating:\u003c\/strong\u003e 20,000A at 300VDC\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\u003eConstruction:\u003c\/strong\u003e Industrial Cartridge\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Fuse Block \/ Clip \/ Holder\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Holder Series:\u003c\/strong\u003e LFR60060 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\u003eThe FLSR040-ID is a UL Class RK5 fuse designed to meet the performance requirements of this fuse class.
