FAQs
The FCF50RN is designed for industrial control and protection in panels, motor drives, PLC enclosures, and switchgear. It uses a 50 A, 600 Vac/600 Vdc rating with a 300 kAIC AC interrupt capability, making it well-suited for high-energy industrial loads and dense control circuits. Its blade-end connection supports straightforward panel retrofits and maintenance planning.
Key ratings include a 50 A amperage, a voltage rating of 600 Vac and 600 Vdc, and interrupt ratings of 300 kAIC at 600 Vac and 50 kAIC at 600 Vdc. It operates over a frequency range of 50–60 Hz and is a fast-acting Class CF fuse suitable for rapid fault isolation in automation systems.
Install by aligning the blade-end terminals with the corresponding fuse holder in the panel. Ensure voltage is de-energized before replacement. The 2.13 in length, 1.9 in height, and 1 in width fit standard holders, and the non-indicating design reduces unnecessary visual checks. Always verify compatibility with TCFH60N or CCP2-3-60CF accessories when retrofitting.
The FCF50RN is UL Listed, CSA Certified, and CE marked with RoHS compliance. These certifications support global compliance requirements and ease procurement across North American and European facilities, reducing validation time for new builds and maintenance projects.
Yes. The product is specified as Used with TCFH60N and CCP2-3-60CF, ensuring straightforward integration in Eaton protection schemes. The blade-end design supports quick swaps in compatible fuse holders and reduces spare-part variety for controlled environments.
