Bussmann Class CC fuses provide 10X better current limitation to help prevent equipment damage caused by short circuit events. They are ideal for critical industrial or commercial applications that have specific current limitation requirements. Rejection type fuse fits both standard and rejection-style holders.

Time-Delay, Branch Circuit, Rejection-Type Fuse

Agency Information:   CE, Std. 248-4, Class CC, UL Listed, Guide JDDZ, File E4273, CSA Certified; Class 1422-02, File 53787–HRC-MISC, Class CC CSA
Typical Applications:  Line Protection, Small Control Transformers • Industrial Control • Isolated, In-Line Fuse Holders


  • Time delay compatible with inrush characteristic of small control transformers
  • Current limitation at Class CC levels provides maximum component short-circuit current rating protection
  • 200kA interrupting rating provides high ratings for control circuit locations
  • Class CC rejection feature, with appropriate fuse block, prevents inserting lesser-rated
  • -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
