Cooper DFJ-400 Dfj - 600vac/450vdc, 1-600a high speed fuse Datasheet

Drive Fuse Class J
DFJ — 600Vac/450Vdc, 1-600A High Speed Fuse
Features and Benefits
• Easily coordinated with existing and new variable speed
drives and electric controllers.
• Standard Class J dimensions allowing the use of readily
available fuse blocks, holders, and switches.
• Allows the lowest let-thru energy of any branch circuit
overcurrent protective device.
Typical Applications
• Protection of AC and DC drives
• Equipment using power semiconductor devices
Recommended Fuse Blocks and Holders
Description: High speed, current-limiting fuse. The Bussmann
Drive Fuse will provide 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.
Fuse Amps
Construction: Melamine tube with silver fuse element.
