With a 5 A rating and dual‑element, time‑delay construction, it manages motor‑ and transformer‑type surge currents without nuisance interruptions—yet responds quickly to sustained overloads or short‑circuits. Rated at 600 V AC (300 V DC) and boasting an interrupting capacity of up to 200,000 A at 600 V AC and 20,000 A at 300 V DC, this Class RK5 fuse gives you peace of mind in critical circuits. Its non‑indicating design, ferrule‑end × ferrule‑end termination, and standard 5-inch body length mean excellent compatibility with most existing panels, motor starters, and control systems.\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 Design:\u003c\/strong\u003e Lets harmless inrush currents (for example, from motors or large transformers) pass without tripping, while instantly protecting on sustained fault conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Interrupting Capacity:\u003c\/strong\u003e 200 kA at 600 V AC, 20 kA at 300 V DC—ensuring safe operation in high‑fault‑current circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact, Install‑Ready Form Factor:\u003c\/strong\u003e A 5‑inch (L) × 0.81‑inch (W) × 0.81‑inch (H) cartridge with ferrule‑end terminations provides easy drop‑in replacement with minimal fuss.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduced Service \u0026amp; Maintenance Needs:\u003c\/strong\u003e Because it handles surge currents gracefully and maintains cooler operation, you’ll see fewer trips and less downtime.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Compatibility:\u003c\/strong\u003e Fits standard Class RK5 fuse holders, control panels, motor circuits, HVAC systems and more without special adapters.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e FRS‑R‑5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e 5 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 600 V AC \/ 300 V DC\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 Minimum 10 seconds at 500% rated current\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type:\u003c\/strong\u003e Ferrule‑end × Ferrule‑end\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class:\u003c\/strong\u003e RK5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Indicator:\u003c\/strong\u003e Non‑indicating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eLength: 5.00 in\u003c\/li\u003e\n\u003cli\u003eWidth: 0.81 in\u003c\/li\u003e\n\u003cli\u003eHeight: 0.81 in\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Approx. 0.14 lb\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\u003eCertifications:\u003c\/strong\u003e UL 248‑12 compliant for Class RK5 fuses; CSA C22.2 No. 248.12; CE Marked.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnvironmental Compliance:\u003c\/strong\u003e Designed in accordance with RoHS standards for safe and sustainable use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe FRS‑R‑5 is ideal in applications where equipment uptime, reliable circuit protection, and tolerance of high inrush currents are essential—think motor control centers, conveyor systems, HVAC starter panels, automation machinery, and industrial power panels.
