Industrial FNQ-R-1-1 Time Delay Relay Class CC

The FNQ-R-1-1 is part of Eaton’s Bussmann FNQ-R Class CC time-delay fuse family, a 600 V AC dual-element, current-limiting device designed to protect branch circuits while tolerating brief inrush currents. FNQ‑R fuses are time‑delay, Class CC devices with ratings spanning from 1/4 A up to 30 A and interrupting ratings up to 200 kA at 600 VAC. Typical form factor for FNQ‑R devices is about 13/32 in wide by 1-1/2 in long, and the 1 A rating variant is commonly specified for 600 VAC operation. These fuses are used in industrial and commercial panels to safeguard motors, transformers, lighting, and other loads where brief surges occur, providing reliable protection without nuisance tripping.
