The Eaton Bussmann FNQ-R-15 is a heavy-duty, 15 Amp branch circuit cartridge fuse engineered for high-reliability industrial power distribution and control circuits. As a member of the high-performance Limitron™ family, this Class CC fuse features a dual-element architecture providing excellent time-delay characteristics—withstanding up to 12 seconds under a 200% overload condition. This delay eliminates nuisance blowing caused by high-inrush currents from inductive motor startups and large control transformers. Equipped with a physical rejection tip to prevent the installation of lower-rated supplementary fuses, its premium melamine tube body delivers superior current limitation to isolate and protect sensitive downstream components from intense short circuits.
