Eaton TCF25RNW Fuse - Class CF, 50 kAIC, 690V
Part Number: TCF25RNW
Quick Summary
TCF25RNW fuse provides reliable Class CF protection for panel and motor circuits. Engineers often contend with nuisance trips during startup surges, and a non-indicating blade-end fuse can complicate fault tracing. UL Listed for safety, CSA Certified for North American compliance, and CE marked RoHS compliant for global installations, this model meets essential regulatory requirements. The design supports compact panel layouts, easy field replacement, and a 50 kAIC interrupt rating at 690 VAC, delivering predictable protection in demanding environments. By pairing high performance with a standard form factor, it helps minimize downtime and simplify procurement while maintaining strict safety and environmental standards. This makes it well-suited for industrial control panels, feeders, and drive applications where reliable time-delay protection is critical.

Eaton Specification Sheet - TCF25RNW
The 25 A, 690 VAC rating with dual elements provides extended protection during inrush, reducing the risk of nuisance trips while safeguarding downstream equipment in motor and drive circuits. This time-delay, Class CF fuse design improves coordination with upstream protection and allows controlled fault clearing, which translates to substantial downtime reduction in manufacturing lines. The blade-end connection and finger-safe, glass-filled PES housing support safer handling during installation and maintenance, lowering injury risk for technicians in busy industrial spaces. UL Listed, CSA Certified, and CE RoHS compliant credentials simplify regulatory approvals and vendor qualification, reducing project lead times and compliance costs. Its compact footprint enables denser panel layouts and easier retrofits, while standard packaging keeps inventory simple for maintenance teams. The fuse is compatible with related Bussmann products like TCFH30NW, broadening replacement options without extensive panel rewiring. In practice, users experience predictable tripping behavior, easier fault diagnosis, and lower total cost of ownership due to longer service intervals between replacements.

FAQs
TCF25RNW uses a blade-end connection designed to fit standard Bussmann/U.S. panel configurations. It is compatible with typical control panels that accept Class CF, time-delay fuses and is intended for 690 VAC systems. When retrofitting, verify bus bar spacing and clip fitment to ensure a secure, safe installation with finger-safe housing.
Key specs include 25 A amperage, 690 VAC rating, 50 Hz to 60 Hz frequency range, 50 kAIC interrupt rating, and Class CF time-delay. These specs support reliable protection for motor circuits and drives, allowing safe interruption at high fault currents while tolerating startup surges without nuisance of premature trips.
Yes. With a 25 A rating, 690 VAC, and dual-element time-delay design, the TCF25RNW is well-suited for motor control centers and drive applications that experience startup inrush. Its Class CF characteristics provide selective coordination with upstream protection, reducing unnecessary downtime while preserving equipment safety.
The TCF25RNW is UL Listed, CSA Certified, and CE RoHS Compliant. UL Listed ensures recognized safety approvals in the U.S., CSA Certified validates compliance in North American markets, and CE RoHS marks support European market access and environmental standards. Together, these certifications simplify procurement, design approval, and regulatory compliance across global projects.
The time-delay, Class CF fuse reduces nuisance tripping during normal operating surges, which lowers unscheduled downtime. Its finger-safe design minimizes maintenance risk for technicians, while its compact form factor aids in denser panel layouts, saving cabinet space. Overall, this contributes to lower maintenance costs, predictable protection, and quicker spares provisioning, improving total cost of ownership.
