The FLSR250 combines a 250-amp continuous rating, 600V AC \/ 300V DC capability, dual-element construction, and time-delay operation in a knife-blade fuse. Its Slo-Blo characteristics allow appropriate short-duration startup or inrush current to pass without the fuse opening unnecessarily, while still providing overcurrent protection within its specified ratings. This particular FLSR250 is the non-indicating version, so that's worth checking when you're replacing an existing fuse.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e250A continuous rating – Matches equipment and circuits that specifically call for a 250-amp Class RK5 fuse.\u003c\/li\u003e\n\u003cli\u003eUp to 600V AC – Suitable for compatible AC applications within the published voltage rating.\u003c\/li\u003e\n\u003cli\u003e300V DC rating – Adds flexibility for correctly specified DC applications up to 300V.\u003c\/li\u003e\n\u003cli\u003eSlo-Blo \/ time-delay operation – Helps handle appropriate short-duration startup and inrush currents without nuisance opening.\u003c\/li\u003e\n\u003cli\u003eDual-element construction – Gives the FLSR250 its time-delay operating characteristics.\u003c\/li\u003e\n\u003cli\u003eClass RK5 fuse – An important specification when replacing or matching existing circuit protection.\u003c\/li\u003e\n\u003cli\u003eKnife-blade design – Fits compatible fuse blocks, clips, and holders designed for this configuration.\u003c\/li\u003e\n\u003cli\u003eNon-indicating version – A useful detail to verify when matching an existing FLSR250 installation.\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 FLSR250\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 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 250A\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:\u003c\/strong\u003e Knife-Blade\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\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 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 identifies the FLSR250 as a Class RK5 fuse.

Its time-delay characteristics are especially useful in properly specified circuits where brief startup or inrush currents are a normal part of operation.\u003cbr\u003e\u003cbr\u003eIt's also well suited to replacement work where an existing FLSR250 250A fuse needs to be matched accurately. That's where it's easy to focus on the big “250A” marking and overlook the rest. Check the RK5 class, voltage rating, time-delay operation, interrupting capacity, knife-blade configuration, and non-indicating design as well.\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.
