Eaton Specification Sheet - TCF80RNW
High-current, time-delay protection for motors and drives is provided by the 80 A rating, 690 Vac operation, 30 kAIC interrupt rating, and a 10 second delay at 500%. This combination reduces nuisance trips during motor start-ups and inrush events, delivering measurable uptime gains and lower maintenance costs in manufacturing lines and HVAC systems. The Class CF time-delay fuse design protects critical loads without sacrificing responsiveness to genuine faults, enabling safer power distribution in control panels and distribution cabinets. The blade-end connection and 35 mm DIN rail chassis mounting simplify installation and replacement, while finger-safe construction minimizes maintenance risk in crowded cabinets. The glass-filled PES body delivers durability in harsh environments, supporting long service life in telecom, automation, and packaging applications. UL Listed, CSA Certified, CE RoHS compliance streamline procurement and regulatory audits, easing cross-border deployments and supplier qualification. Used with TCFH100NW devices, these fuses enable modular protection schemes for scalable motor control and protection architecture across line-side and load-side protection.

FAQs
The TCF80RNW is designed for chassis mounting on a 35 mm DIN rail with a blade-end connection, enabling quick plug-in installation in standard control panels. Its finger-safe design reduces risk during routine maintenance, and the standard packaging simplifies stocking and replacements in panel shops.
It is rated for 80 A with a 690 VAC maximum voltage and 30 kAIC interrupt capacity. The time-delay (slow-blow) characteristic allows short inrush currents common to motors and transformers, reducing nuisance trips while still providing fast clearance for actual faults. This balance supports higher uptime in dynamic equipment loads.
Yes. The fuse is UL Listed and CSA Certified, CE marked, and RoHS compliant, ensuring regulatory alignment for broad industrial use. This supports easier approvals for equipment destined for regulated markets and simplifies supplier qualification.
Yes. The TCF80RNW is designed to be used with TCFH100NW in modular protection schemes, suitable for panelized power distribution, motor control centers, and other industrial automation assemblies that require dependable protection with compatible sibling devices.
Being non-indicating, external status monitoring is recommended for high-availability environments. Its robust DIN-rail mounting and durable PES body contribute to lower replacement costs and reduced field servicing time, delivering a favorable return on investment through improved uptime and easier stock management.
