The FNQ-R-3 is a Class CC, current-limiting, time-delay fuse that provides advanced protection for electrical systems. It features a current rating of 3A, a voltage rating of 600Vac, and a high 200kA interrupting rating, making it compliant with NEC® Section 110.9 for large capacity systems. This fuse offers a significant time-delay, exceeding the UL minimum of 12 seconds at 200% current, which allows it to handle the high inrush currents typical of control circuit transformers. The FNQ-R-3 is a rejection-type fuse suitable for critical industrial and commercial applications, including branch circuits, line protection, and industrial controls.
