Eaton FCF30RN Fuse - UL Listed Class CF Fast-Acting

Fast-acting Class CF design delivers rapid interruption during overcurrent events, protecting life-safety circuits and downstream devices. The business impact is reduced downtime and lower repair costs by stopping faults before they cascade into equipment damage. This pattern is particularly advantageous in motor drives, control panels, and power distribution cabinets where precise clearing at 200% overload can prevent widespread outages. High interrupt rating of 50 kAIC at 600 Vdc and 300 kAIC at 600 Vac provides robust fault tolerance across DC and AC circuits. The business outcome is improved system reliability and compliance with short-circuit requirements in feeders and switchgear. Applications include industrial automation cabinets, power distribution blocks, and machine control circuits that demand dependable protection without nuisance trips. Non-indicating fuse with blade-end connection simplifies field installation and reduces diagnostic complexity. With a compact 1.88 in length and standard packaging, technicians can swap fuses quickly without tools or adapters. This compatibility supports multi-vendor panels and eases stocking from Eaton Bussmann catalogs. Rugged construction rated from -40° to 80°C, with glass-filled PES housing and electroless tin-plated copper terminals, ensures dependable operation in harsh environments. The design also supports thermal cycling and overload resilience, extending service life and reducing maintenance intervals in equipment enclosures and outdoor installations. CE marked, RoHS compliant, UL Listed, and CSA Certified, this fuse meets global regulatory expectations. Certifications simplify procurement for international projects and allow unified qualification testing. The combination of compliance and fast performance helps engineering teams meet safety standards while maintaining compact bill-of-materials footprints. Designed to slot into Eaton Bussmann series line and compatible with TCFH30N and CCP2-3-30CF assemblies, the FCF30RN offers straightforward installation in standard blade-end holders. This ease of integration reduces engineering time, supports scalable protection schemes, and aligns with a broad catalog of replacement fuses for maintenance programs.
