Features:
• The Class CC FNQ-R Limitron fuse meets the needs of con-
trol circuit transformer protection
• Current-limitation protects downstream components against
damaging thermal and magnetic effects of short-circuit
currents
• Rejection feature of FNQ-R fuses meets the need for a
rejection type fuse in equipment where available fault
current can exceed 10kA
• High inrush time-delay so 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
Applications:
• Branch Circuits • Line Protection
• Small Control Transformers • Industrial Control
