Agency information
•
UL Listed, Std. 248-4, Class CC, Guide JDDZ,
File E4273
•
•
CSA Certified, Class CC CSA, Class 1422-01,
File 53787–HRC-MISC
The Class CC FNQ-R Limitron fuse meets the
needs of control circuit transformer protection.
•
•
CE
•
RoHS compliant*
FNQ-R fuses can be sized according to NEC®
and UL requirements and still allow the high
inrush currents, with significantly more timedelay 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.
