Eaton WCF70RN Fuse - Class CF, 70 A
Part Number: WCF70RN
Quick Summary
The Eaton WCF70RN fuse is a Class CF fast-acting current-limiting cube fuse designed for low-voltage protection in control panels, switchgear, and motor-drive applications. Engineers often contend with nuisance trips, space limits, and inconsistent protection across panels; this device helps mitigate those pain points with dual-element current limiting and a compact footprint. CE marking and RoHS compliance reflect alignment with critical safety and environmental standards, while its finger-safe design reduces handling risks during maintenance. In practice, the WCF70RN enables reliable circuit protection and streamlined procurement in LV distribution, supporting safer, more efficient industrial electrical protection across plant networks.
