Part number
WCF6RN

Quick Summary

The Eaton WCF6RN fuse provides fast-acting protection for industrial power circuits in control panels. Engineers face nuisance trips and crowded enclosures; this dual-element cube fuse offers reliable current limiting in a compact, finger-safe package. It carries CE marking and RoHS compliance for global installations, and its Class CF designation aligns with Bussmann wind CUBEFuse standards. For panel builders and maintenance teams, the 6 A rating paired with a 50 kA interrupting rating translates to higher uptime, safer operations, and simplified spare-part inventories. Its standard dimensions — 1.88 in long, 0.75 in wide, 1 in high — ensure easy integration into existing Bussmann-based assemblies.
