Eaton TCF30RN fuse - UL Listed Class CF Time Delay
Part Number: TCF30RN
Quick Summary
TCF30RN fuse provides time-delay protection for industrial control panels and power distribution. Engineers often struggle with startup nuisance trips and unpredictable short-circuit responses that drive downtime and maintenance costs. UL Listed, CSA Certified, CE Marked and RoHS compliant, these fuses meet global safety and environmental standards while supporting cross-border projects. With a Class CF time-delay profile, dual elements, and a blade-end connection for 35 mm DIN-rail mounting, they fit compact spaces and simplify panel assembly. The 30 A rating and 600 Vac/300 Vdc capability align with common industrial controls, motor drives, and power supplies. This combination minimizes design trade-offs, improves reliability, and helps service teams plan maintenance more predictably.

Time-delay Class CF fuse delivers selective protection during motor start-up and transient overloads, reducing nuisance trips while preserving critical equipment. This design translates to fewer unnecessary outages and smoother line operation in conveyors, pumps, and drives. Dual-element construction minimizes arc energy and accelerates fault clearance, enhancing safety and protecting downstream components in harsh industrial environments. The 30 A amperage rating is well-suited for panel feeders and branch circuits, enabling compliant protection without oversizing, which reduces spare-part inventories and total cost of ownership. High interrupt ratings—300 kAIC at 600 Vac and 100 kAIC at 300 Vdc—provide robust fault protection in high-current systems like CNC machines and packaging lines, improving system resilience. Blade-end connection with 35 mm DIN-rail mounting supports fast, tool-free integration into standard control cabinets, reducing installation time and field labor. Finger-safe design adds technician safety during maintenance, while CE RoHS compliance ensures regulatory readiness for global deployments.

FAQs
Install the blade-end connected fuse onto the DIN rail using standard DIN-rail mounting clips. Verify the panel space, ensure correct orientation for accessible replacement, tighten securely, and confirm the circuit rating matches the 30 A, 600 Vac/300 Vdc capability before power-up.
The TCF30RN uses a Class CF time-delay profile designed for motor start-up surges and transient overloads. It’s ideal for motor control centers, drives, panel boards, and other power distribution points where selective fault protection and nuisance-trip resistance are critical.
Yes, it supports 300 Vdc with an interrupt rating of 100 kAIC, alongside 600 Vac operation. The device is rated at 30 A and provides dual-element protection, suitable for mixed AC/DC control circuits common in industrial environments.
The TCF30RN is UL Listed, CSA Certified, CE Marked, and RoHS compliant. These certifications verify safety, interoperability, and environmental compliance, reducing regulatory barriers in global deployments and helping meet supplier and customer requirements.
With time-delay protection that minimizes nuisance trips and a high interrupt rating for fault currents, downstream equipment experiences fewer outages and shorter downtime. Easy DIN-rail installation lowers labor costs during panel upgrades, and the compact blade-end design reduces spare-parts and stock complexity.
