Features:
•
300Vdc (15 & 20A)
•
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.
