Features and Benefits
? Separate overload and short-circuit elements provide time
delay for sizing as close as 125% of motor FLA.
? 2:1 selective coordination amp ratio (within the Cooper
Bussmann RK5 fuse family) prevents overcurrent events
from opening upstream Fusetron fuses.
? Insulated end caps for 225A-600A fuses reduces exposure
to live parts and extends air gap to distance between
blades of adjacent mounted fuses or to housing.
