Industrial FNQ-R-7-1 Current-Limiting Time-Delay Fuse

The FNQ-R-7-1 current-limiting time-delay fuse from Eaton Bussmann is a LIMITRON Class CC fuse designed for reliable industrial circuit protection. As part of the FNQ-R family, it is a current-limiting, time-delay device (dual-element) with a 7 A rating and a 200 kA interrupting rating at 600 VAC. This non-indicating, rejection-style fuse is intended for line protection, small control transformers, and industrial control circuits, where brief inrush currents can occur without nuisance trips. The fuse is UL-listed and designed to meet NEC/UL requirements while delivering extended time-delay during faults to minimize downstream damage. The body size is typically compatible with standard holders—about 10.3 mm in diameter and 38.1 mm long (roughly 0.405" x 1.50"), with an overall length near 13/32" x 1-1/2" in common catalog listings. For higher-current needs, the FNQ-R family also includes the FNQ-R-7-1/2 variant (7.5 A) with the same 600 VAC rating and time-delay characteristics.
