Bussmann DFJ Drive Fuses
Bussmann offers a wide range of current-limiting DFJ high speed fuses which are UL Listed Class J fuses.
The DFJ drive fuses provide maximum protection for AC and DC drives and controllers and meet NEC® branch circuit protection requirements. They have a current rating of 1-600A and a voltage rating of up to 600Vac.
The DFJ drive fuse has the lowest I2t of any branch circuit fuse to protect power semiconductor devices that utilise diodes, gate turn-off thyristors, SCRs and SSRs.
Features
- Easily co-ordinated with existing and new variable speed drives and electric controllers
- Class J fuses allow the use of readily available fuse blocks, holders and switches
- Enables the lowest let-through energy of any branch circuit overcurrent protective device
