The Eaton Bussmann FRS‑R‑12 is a dual‑element, time‑delay fuse rated at 12 amps and built for heavy‑duty protection in industrial and commercial electrical systems. With a voltage rating of 600 VAC or 300 VDC, this fuse delivers a 10‑second (minimum) time−delay at 500% of its rating—making it ideal for motor startup and inrush conditions without nuisance blowing. Its interrupting capacity reaches up to 200 kA at 600 VAC and 20 kA at 300 VDC, offering high fault‑current protection in demanding environments. Designed in the Class RK5 format with ferrule‑end x ferrule‑end connections and a 9.63″ length by 1.61″ diameter body, it fits standard RK5 fuse blocks for easy integration. If you’re looking for a reliable, time‑delay fuse with strong fault‑clearing capability and the performance to back up critical loads, this fuse delivers with confidence.\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\u003eTime‑Delay Dual‑Element Design:\u003c\/strong\u003e Permits temporary overloads (as seen with motor inrush or transformer energizing) while still responding fast to real fault conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Fault‑Current Interrupting Capability:\u003c\/strong\u003e Rated for up to 200 kA at 600 VAC and 20 kA at 300 VDC, ensuring safe operation in high‑stress circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandardized RK5 Format:\u003c\/strong\u003e Uses familiar ferrule‑end terminations in a classic 9.63″ x 1.61″ cartridge size so you can drop it into many standard fuse holders with minimal hassle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon‑Indicating Construction:\u003c\/strong\u003e Keeps the design simple and reliable, with no external indicator to maintain.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngineered for Harsh Conditions:\u003c\/strong\u003e While not labelled “robust,” the build is crafted to withstand the rigors of industrial applications, giving you peace of mind in demanding installations.\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‑12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e 12 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 600 VAC \/ 300 VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 200 kA at 600 VAC, 20 kA at 300 VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResponse Time:\u003c\/strong\u003e Minimum 10 seconds at 500% of rated current\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class:\u003c\/strong\u003e RK5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type:\u003c\/strong\u003e Ferrule‑end x ferrule‑end\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 9.63″ (L) × 1.61″ (W) × 1.61″ (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e ~1.3 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\u003cstrong\u003eComplies with electrical protection standards, including UL 248‑12 and CSA C22.2 No. 248.12 for Class RK5 fuses.\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCE Marked for global use.\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eManufactured by a trusted name in circuit protection, ensuring you meet both performance and safety benchmarks.\u003c\/strong\u003e\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‑12 shines in environments where both inrush currents and high fault levels exist.
