The FNQ-R-25 is a time-delay branch circuit Rejection-type Fuse for use with the line protection, small control transformers. The time-delay is compatible with inrush characteristic of small control transformers. The 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 features with appropriate fuse block, prevents inserting lesser-rated supplementary fuse.
