This 350-amp dual-element time-delay fuse is rated for up to 600V AC and 300V DC and uses knife-blade construction for compatible fuse blocks, clips, and holders. Its Slo-Blo\/Time Lag (T) opening characteristic allows appropriate short-duration startup or inrush current to pass without the fuse responding as in a fast-acting design.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e350A continuous current rating – Intended for equipment and circuits specifically requiring a 350-amp fuse.\u003c\/li\u003e\n\u003cli\u003eClass RK5 fuse – Provides the fuse-class specification needed when matching an existing installation or equipment requirement.\u003c\/li\u003e\n\u003cli\u003eIndicating design – Helps maintenance personnel check fuse status during troubleshooting and distinguish this model from the standard non-indicating version.\u003c\/li\u003e\n\u003cli\u003eSlo-Blo \/ time-delay operation – Allows appropriate temporary startup and inrush currents without opening as quickly as a fast-acting fuse.\u003c\/li\u003e\n\u003cli\u003eDual-element construction – Supports the time-delay operating characteristics specified for the FLSR350-ID.\u003c\/li\u003e\n\u003cli\u003eKnife-blade construction – 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 FLSR350-ID\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Reference:\u003c\/strong\u003e FLSR350ID\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 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 350A\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 20,000A (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 LFR60400 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 product information specifically identifies the FLSR350-ID as a Class RK5 fuse.

Its time-delay behavior is useful in properly specified circuits where brief startup or inrush currents are expected during normal equipment operation. Instead of treating every short-current increase as an immediate fault condition, the fuse's Slo-Blo characteristics provide a delayed response for this type of protection.\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.
