This dual-element cartridge fuse is rated for 12A continuous current, up to 600VAC and 300VDC, and uses a Slo-Blo\/time-delay design. Installation is through a compatible fuse block, clip, or holder, including the specified LFR60030 Series holder. Whether you're maintaining existing electrical equipment or replacing a fuse with matching specifications, the FLSR012 offers a straightforward 12A, 600V Class RK5 fuse with time-delay performance designed for real-world electrical applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e12A continuous current rating for equipment and circuits requiring 12-amp overcurrent protection.\u003c\/li\u003e\n\u003cli\u003eRated up to 600VAC, making it suitable for compatible higher-voltage AC systems.\u003c\/li\u003e\n\u003cli\u003eA 300 VDC maximum rating expands its usefulness for qualifying DC applications.\u003c\/li\u003e\n\u003cli\u003eTime-delay \/ Slo-Blo operation allows the fuse to handle temporary current surges without opening unnecessarily.\u003c\/li\u003e\n\u003cli\u003eIts dual-element design provides time-delay characteristics while maintaining overcurrent protection.\u003c\/li\u003e\n\u003cli\u003eClass RK5 construction is designed for applications specifically suited to this fuse class.\u003c\/li\u003e\n\u003cli\u003eIndustrial cartridge format works with the appropriate fuse block, clip, or 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 FLSR012\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\u003eCurrent Rating:\u003c\/strong\u003e 12A\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\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\u003eFuse Style:\u003c\/strong\u003e Dual Element\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction \/ Size:\u003c\/strong\u003e Industrial Cartridge\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\u003eInterrupting Rating:\u003c\/strong\u003e 200,000A at 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdditional Published 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\u003eMounting Method:\u003c\/strong\u003e Fuse Block \/ Clip \/ Holder\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecified Holder Series:\u003c\/strong\u003e LFR60030 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 supplied specifications do not provide detailed information on material composition, environmental compliance, or certification for the FLSR012.
