Bussmann(R) CC-TRON(R) FNQ-R Time-Delay Fuses TM 1TM, 600 Volt, to 30 Amps Dimensional Data General Information: * The Bussmann CC-TRON(R) (FNQ-R) was designed to meet the needs of control circuit transformer protection. * Current-limitation protects down stream components against damaging thermal and magnetic effects of shortcircuit currents. * High inrush time-delay. Control circuit transformers can experience inrush currents up to 85 times their full-load current rating. 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. * Melamine tube.
