Features:
• Provides 10X better current limitation to help prevent
equipment damage caused by short-circuit events.
• 200kA interrupting rating complies with NEC
®
Section 110.9
for today's large capacity systems.
• Fast-acting fuse helps prevent equipment damage caused
by short-circuit events.
• Rejection type fuse fits both standard and rejection-style
holders.
• The Class CC FNQ-R Limitron fuse meets the needs of
control circuit transformer protection.
• 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.
• Ideal for critical industrial or commercial applications that
have specific current limitation requirements.
Applications:
• Branch Circuits
• Small Control Transformers
• Line Protection
• Industrial Control
