Motors and transformers are familiar examples—startup current can be considerably higher than normal running current, and you don't necessarily want that brief surge opening the fuse. The FLSR070 uses a dual-element, time-delay design to accommodate appropriate short-duration inrush while still providing overcurrent protection during a fault or sustained overload.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e70A continuous current rating for circuits requiring 70-amp overcurrent protection.\u003c\/li\u003e\n\u003cli\u003eClass RK5 dual-element design combines time-delay operation with high-capacity fault protection.\u003c\/li\u003e\n\u003cli\u003eRated for applications up to 600VAC and 300VDC.\u003c\/li\u003e\n\u003cli\u003eSlo-Blo\/time-delay operation helps the fuse tolerate appropriate temporary startup and inrush currents without unnecessary opening.\u003c\/li\u003e\n\u003cli\u003eKnife-blade construction provides the physical configuration required by compatible higher-amperage fuse blocks and holders.\u003c\/li\u003e\n\u003cli\u003eNon-indicating design for applications where a built-in fuse-status indicator isn't required.\u003c\/li\u003e\n\u003cli\u003eCompatible with the appropriate fuse block, clip, or holder, including the specified LFR60100 Series PG holder.\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 FLSR070\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e FLSR\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\u003eContinuous Current Rating:\u003c\/strong\u003e 70A\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 (T) \/ Time Delay\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Interrupt Amperage:\u003c\/strong\u003e 200,000A at 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdditional Manufacturer-Specified AC Interrupt Amperage:\u003c\/strong\u003e 300,000A at 600VAC\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\u003eConstruction \/ Size:\u003c\/strong\u003e Knife-Blade\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFamily Style:\u003c\/strong\u003e Dual Element Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndicating:\u003c\/strong\u003e No\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 LFR60100 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 FLSR070 is identified as a Class RK5 fuse, an important specification when selecting a fuse for existing equipment or a new electrical system. Matching the amperage alone isn't enough; the fuse class, voltage, interrupting capacity, operating characteristics, and physical configuration must also meet the application's requirements.\u003cbr\u003e\u003cbr\u003eFor projects that require specific UL, CSA, RoHS, REACH, environmental, or material-compliance documentation, confirm the current documentation for the exact FLSR070 catalog number.

A motor, for example, may draw substantially more current at startup than at operating speed. Transformers can behave similarly when first energized. The time-delay characteristic allows a properly designed circuit to accommodate these brief conditions without sacrificing protection against sustained overloads and short circuits.\u003cbr\u003e\u003cbr\u003eThat makes this 70A Class RK5 fuse well suited to properly specified motor circuits, transformers, motor-control equipment, industrial machinery, feeders, switchboards, service equipment, and other commercial or industrial power-distribution applications requiring its electrical characteristics.\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.
