(U.L.) Agency Approvals: U.L. Listed, Std. 248-4, Class CC, Guide JDDZ, File E4273 CSA Certified, Class CC CSA, Class 1422-01, File 53787–HRC-MISC General Information: • The Bussmann CC-TRON® (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. • Rejection feature. FNQ-R fuses meet the U.L. 508, paragraph 19.2.4 requirement that control circuit fuses used in equipment listed for use with more than 10,000 ampere available must have an adequate interrupting rating and must be rejection type. • 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 U.L. requirements and still allow the high inrush currents, with significantly more time-delay than the U.L. minimum value of 12 seconds at 200% for Class CC fuses. • Melamine tube. Nickel-plated brass endcaps.
