The FNQ-R-7-1/2 is a 7.5A LIMITRON™ Advanced Protection class CC Current-limiting Time-delay Fuse provides 10X better current limitation to help prevent equipment damage caused by short circuit events. 200kA interrupting rating complies with NECR Section 110.9 for today's large capacity systems. The class CC FNQ-R Limitron fuse meets the needs of control circuit transformer protection. FNQ-R fuses can be sized according to NECR 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. Current limitation at class CC levels provides maximum component short-circuit current rating protection. Class CC rejection feature, with appropriate fuse block, prevents inserting lesser-rated supplementary fuses.
