Description:
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.
Typical applications
•
Protection of AC and DC drives
•
Equipment using power semiconductor
devices
