Equipment is down, work is piling up, and maintenance crews need answers.\u003c\/p\u003e\n\u003cp\u003eThat's where the Littelfuse LLSRK225ID comes in. This 225-amp Class RK1 time-delay indicating fuse combines high-capacity electrical protection with a simple troubleshooting feature: a built-in indicator window that darkens when the fuse opens. Instead of starting from scratch, technicians have a visible clue that helps them identify the affected fuse.\u003c\/p\u003e\n\u003cp\u003eBut there's more to this fuse than its indicator. Motors and other industrial equipment often draw extra current briefly when starting or cycling. That doesn't always mean there's a problem. The LLSRK225ID uses a time-delay design to accommodate these normal, temporary surges while still protecting against sustained overloads and short circuits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e225A Class RK1 Protection\u003c\/li\u003e\n\u003cli\u003eBuilt-In Blown-Fuse Indicator\u003c\/li\u003e\n\u003cli\u003ePatented Indicator™ Technology\u003c\/li\u003e\n\u003cli\u003eTime-Delay Operation\u003c\/li\u003e\n\u003cli\u003eCurrent-Limiting Design\u003c\/li\u003e\n\u003cli\u003eHigh Interrupting Capacity\u003c\/li\u003e\n\u003cli\u003ePrecision-Formed Short-Circuit Elements\u003c\/li\u003e\n\u003cli\u003eSolid-State Overload Section\u003c\/li\u003e\n\u003cli\u003eNo Spring-Loaded Overload Mechanism\u003c\/li\u003e\n\u003cli\u003eImproved Cycling Characteristics\u003c\/li\u003e\n\u003cli\u003eReduced Nuisance Openings\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\u003eManufacturer:\u003c\/strong\u003e Littelfuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e LLSRK225ID\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e LLSRK_ID\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Family:\u003c\/strong\u003e POWR-PRO\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Industrial Cartridge Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class:\u003c\/strong\u003e Class RK1\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current Rating:\u003c\/strong\u003e 225A\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\u003eTerminal Style:\u003c\/strong\u003e Knife-Blade\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlown-Fuse Indication:\u003c\/strong\u003e Yes\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Interrupting Rating:\u003c\/strong\u003e 200,000A at 600V AC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdditional AC Interrupting Rating:\u003c\/strong\u003e 300,000A at 600V AC, subject to applicable manufacturer rating conditions\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupting Rating:\u003c\/strong\u003e 20,000A at 300V DC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShort-Circuit Elements:\u003c\/strong\u003e Precision-Formed\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload Section:\u003c\/strong\u003e Solid-State, No Moving Parts\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\u003eAssociated Fuse Holder Series:\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 Littelfuse LLSRK225ID belongs to the POWR-PRO LLSRK_ID family of Class RK1 time-delay indicating fuses.
