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.
