Fuse Class J 400A 600V 2-Pin Tap Bolt

The Bussmann series DFJ drive fuse is a high speed, current-limiting fuse that provides maximum protection for AC and DC drives and controllers and meet NEC branch circuit protection requirements. The drive fuse has the lowest I2t of any branch circuit fuse to protect power semiconductor devices that utilize diodes, GTOs, SCRs and SSRs.

• Easily coordinated with existing and new variable speed drives and electric controllers.
• Standard Class J dimensions allow using readily available fuse blocks, holders and switches.
• Has the lowest let-through energy of any branch circuit overcurrent protective device.
