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 short-
circuit 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. Nickel-plated brass endcaps.
