The FNQ-R-12 Limitron fuse from Bussmann (Eaton) is a 12 A, 600 V Class CC time-delay, current-limiting fuse with a dual-element, rejection-style design. It uses ferrule-end terminations and measures about 1.5 inches long with a diameter of roughly 0.41 inches, offering an interrupting rating of 200 kA at 600 VAC. The FNQ-R-12 is intended for line protection, small control transformers, industrial control circuits, and branch circuits, with a typical response of 12 seconds at 200% of rated current. This melamine-tube, non-indicating fuse carries CE marking and RoHS compliance, aligning with modern electrical standards.
