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.

Fast-Acting, Branch Circuit, Rejection-Type Fuse

Dimensions:               13/32" X 1-1/2" (10.3mm X 38.1mm)
Volts:                          600Vac (or less)
Amps:                         1/10-30A
IR:                               200kA RMS Sym
Agency Information:    CE, Std. 248-4, Class CC, UL Listed, Guide JDDZ, File E4273, CSA Certified, File 53787, Class 1422-02, RoHS compliant
Typical Applications:   Specialized Circuits • Industrial Control • Isolated, In-Line Fuse Holders (street lighting)


  • Current limitation at Class CC levels provides maximum component short-circuit current protection
  • 200kA interrupting rating provides high ratings for control circuit locations
  • Class CC rejection feature, with appropriate fuse block, prevents inserting lesser-rated supplementary fuses
  • -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
