  • 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 supplementary fuses
