Eaton TCF300 Fuse - Class CF Time-Delay, 300A, UL Listed

Time-delay Class CF dual-element design minimizes nuisance trips during motor starts and transient surges. It provides selective protection that coordinates with upstream breakers to avoid unnecessary outages in panels and switchgear. 300 A amperage rating supports large feeders and motor circuits without excessive fuse replacement, translating into lower maintenance costs and improved line uptime in production lines that rely on heavy loads. With an interrupt rating of 200 kAIC at 600 V, the TCF300 clears faults rapidly, protecting conductors and equipment from high fault currents, while its cube form factor aids panel density and simplifies wiring within crowded control cabinets. UL Listed and RoHS compliant markings provide regulatory assurance across North American and global facilities, and the Class CF designation ensures compatibility with Bussmann series components for proven protection coordination. Finger-safe construction reduces exposure during installation, and the fuse indicator helps technicians quickly confirm status without disassembly. Blade-end connections enable quick mounting in standard Bussmann schemes and support with TCFH400N when used together. This device ships in standard packaging and, at 0.79 lb, adds minimal weight to assemblies while delivering durable glass-filled PES reliability in harsh environments.
