      * FNQ-R-1⁄4 not RoHS complaint.


       

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

  • Line protection

  • Small control transformers

  • Industrial control
