FNQ-R Class CC 600 VAC, 1/4-30A, Time-delay Fuses. Advanced protection Class CC current-limiting, time-delay fuses. Provides 10X better current limitation to help prevent equipment damage caused by short-circuit events. 200kA interrupting rating complies with NEC® Section 110.9 for today’s large capacity systems. Fast-acting fuse helps prevent equipment damage caused by short-circuit events. Rejection type fuse fits both standard and rejection-style holders. The Class CC FNQ-R Limitron fuse meets the needs of control circuit transformer protection. FNQ-R fuses can be sized according to NEC® and UL requirements and still allow the high inrush currents, with significantly more time delay than the UL minimum value of 12 seconds at 200% for Class CC fuses. Ideal for critical industrial or commercial applications that have specific current limitation requirements.
