FNQ-R-1/2

The FNQ-R-1/2 is a CC-TRON®-series 500mA 600VAC time-delay branch circuit Fuse with fiber body, melamine tube and nickel-plated brass endcaps construction, it is designed to meet the needs of control circuit transformer protection, current-limitation protects down stream components against damaging thermal and magnetic effects of short-circuit currents, high inrush time-delay control circuit transformers can experience inrush currents up to 85 times their full-load current rating, these 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. Meets UL listed, standard 248-4, class-CC, guide JDDZ, file E4273 CSA certified, class-CC CSA, class 1422-01.

• 200kA VAC RMS symmetrical Interrupting rating
