Eaton Bussmann FNQR712 Time-Delay Fuse

The Bussmann CC-TRON FNQ-R is a slow blow, time-delay fuse designed for control circuit transformer protection with a 600V rating and suitable for currents from 1 to 30 Amps. It features a 13.5-inch length with a 1% diameter, housed in a cylindrical package with 5AG midget case dimensions of 10x38mm. Constructed with a melamine tube and nickel-plated brass endcaps, it provides high inrush time-delay, protecting downstream components from thermal and magnetic effects caused by short circuits and high inrush currents typical in control transformers.
