Eaton FCF15RN Fuse - UL Listed
Part Number: FCF15RN
Quick Summary
The Eaton Bussmann FCF15RN fuse is a fast-acting Class CF cube fuse that protects power and control circuits. Nuisance outages and costly panel downtime can occur when protection is undersized or response is slow, allowing faults to propagate. UL Listed and CSA Certified with CE marking and RoHS compliance enable global deployment in industrial equipment. With a 15 A rating and broad voltage coverage, it integrates easily into Bussmann arrays and supports fast, reliable protection in electrical panels. Designed for high reliability in demanding environments, it helps minimize downtime, protect downstream devices, and streamline maintenance planning across facilities.

Bussmann series Fast-acting CUBEFuse data sheet no. 2147
Feature: Class CF fast-acting cube fuse design. Business Impact: Rapid interruption limits fault energy, reducing damage to downstream equipment and shortening repair cycles. Application: Control panels, motor drives, and distribution cabinets where swift response is critical. Feature: High interrupt ratings (300 kAIC at 600 Vac; 50 kAIC at 600 Vdc). Business Impact: Enables safe clearance of large short-circuit currents without system-wide outages. Application: Heavy-duty industrial systems with high fault current potential, such as AC drives and switchgear. Feature: UL Listed and CSA Certified with CE RoHS compliance. Business Impact: Facilitates regulatory compliance and global deployment, reducing risk in multinational projects. Application: Equipment intended for markets requiring formal certification and environmental compliance. Feature: Wide operating temperature (-40° to 80°C) and durable materials (glass-filled PES, tin-plated copper terminal). Business Impact: Improves reliability in harsh factory environments and extends service life. Application: Enclosed control panels in automotive, packaging, and process industries. Feature: Blade-end connection and 1-element design. Business Impact: Simplifies installation, replacement, and maintenance, decreasing downtime and stock variety. Application: OEM panels and retrofit projects that prioritize quick, secure swaps. Feature: Compatibility with Bussmann lineup ('Used with' TCFH30N, CCP2-3-30CF). Business Impact: Streamlines procurement and cabinet planning by ensuring seamless integration into existing fuse blocks. Application: Panel upgrades and new equipment where standardized protection is required.

FAQs
The FCF15RN uses a blade-end connection designed to fit standard Bussmann series fuse blocks. This enables quick, secure installation in common control panels and OEM enclosures, reducing assembly time and ensuring proper contact resistance. For retrofit projects, verify the existing blade-end geometry and mounting clearances to avoid misalignment and ensure consistent protection performance.
A 300 kAIC interrupt rating at 600 Vac means the fuse can safely interrupt extremely high fault currents without sustaining damage or causing system-wide faults. This translates to enhanced safety for power distribution panels, minimizes downstream damage, and supports reliable shutoff in demanding industrial environments where fault energies can spike quickly.
Yes. The FCF15RN provides adequate protection for 600 Vdc circuits with a 50 kAIC interrupt rating, offering fast-acting protection with a robust current interrupt capability. When designing DC-powered control or drive systems, ensure proper derating for ambient temperature and verify compatibility with DC link components and enclosure spacing.
Look for UL Listed and CSA Certified markings for formal safety approvals, along with CE marking and RoHS compliance for European and global deployments. These certifications indicate adherence to recognized safety standards, environmental controls, and cross-border use, reducing regulatory risk in multinational projects and helping with procurement approvals.
Plan for straightforward blade-end replacement and maintain an automotive/industrial stock of 1-element Class CF fuses to minimize downtime. Consider operating temperature range (-40°C to 80°C) for enclosure placement, ensure clean contact surfaces on copper alloy terminals, and account for the 15 A rating in protection coordination studies to avoid nuisance trips while still protecting downstream equipment.
