FNQ-R-6/10 EATON Class CC Time-Delay Fuse
The Eaton Bussmann FNQ-R-6/10 (also listed as FNQ-R-6-10) is an industrial-grade, high-performance Class CC current-limiting branch circuit fuse designed for superior electrical protection. Part of the renowned Limitron™ family, this advanced dual-element fuse features a rejection-style rejection tip to ensure proper installation in dedicated Class CC fuse blocks and holders, preventing the substitution of lower-rated fuses.
Engineered with a robust melamine cartridge body and precise ferrule end-to-end connections, it delivers a specialized high-inrush time-delay characteristic (holding 200% of rated load for a minimum of 12 seconds). This makes the 0.6 Amp (600mA) version highly optimized for protecting small control transformers, industrial control circuits, and motor branch circuits where temporary power surges occur.
