Designed for dependable protection in demanding commercial and industrial environments, this Class RK5, 3 A time‑delay fuse handles both short‑circuit events and sustained overloads with ease. With a 600 VAC \/ 300 VDC rating and interrupting capacity of 200,000 amps at 600 V AC (20,000 amps at 300 V DC), this unit stands ready for high‑fault‐current installations. Its dual‑element, time‑delay construction gives you about 10 seconds of tolerance at five times rated current — perfect for equipment with inrush surge like motors, HVAC systems, and inductive loads. Compact at approximately 5 in long and 0.81 in diameter, the FRS‑R‑3 fits well in tight panel configurations where space and reliability both matter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual‑Element Time‑Delay Technology:\u003c\/strong\u003e Offers a built‑in hold‑off for surge peaks during startup (like motors or transformers) and then fast‑acting protection for true overload or short‑circuit situations—reducing nuisance trips and downtime.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Interrupting Capacity:\u003c\/strong\u003e Rated for 200 kA at 600 V AC and 20 kA at 300 V DC, this fuse covers extremely demanding fault‐current environments so your downstream gear stays safer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Footprint:\u003c\/strong\u003e At just 5 in long and ~0.81 in diameter, it’s space‑efficient and fits standard fork\/ferrule end cartridge holders in control panels with tight real estate.\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecise Install Fit:\u003c\/strong\u003e Ferrule end x ferrule end connection makes it easy to install in traditional fuse blocks and simplifies replacement with consistent sizing.\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 FRS‑R‑3\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e 3 A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 600 VAC \/ 300 VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e200 kA at 600 V AC\u003c\/li\u003e\n\u003cli\u003e20 kA at 300 V DC\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResponse Time:\u003c\/strong\u003e 10 seconds at 500% of rated current\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type:\u003c\/strong\u003e Ferrule end × Ferrule end\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\u003eDimensions:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eLength: 5 inches\u003c\/li\u003e\n\u003cli\u003eDiameter: 0.81 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e ~0.14 lb\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndicator:\u003c\/strong\u003e Non‑indicating\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\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUL and CSA Standards:\u003c\/strong\u003e Certified to UL 248‑12 (Class RK5 fuses) and CSA C22.2 No. 248.12 standards, ensuring recognized safety and regulatory compliance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCE Marked:\u003c\/strong\u003e CE‑marked to indicate conformity with applicable European directives when used in appropriate environments.\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturing Quality:\u003c\/strong\u003e Manufactured with attention to durability and reliability, in line with modern industrial protection requirements.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe FRS‑R‑3 excels in applications where equipment is subject to brief surge currents at startup, yet requires strong protection against fault conditions. Ideal for motor control centers, HVAC units, lighting and control panels, industrial control cabinets, and other systems with inductive loads. If you’re replacing older non‑time‑delay fuses, this model allows you to size closer to full load amps—thanks to its time‑delay feature—resulting in better overall protection and potentially lower costs in switch and panel sizing.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\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.
