For branch and small motor protection where
high current limitation is required.
For use in branch circuits where higher
performance and lower power levels are
needed.
Recognized holders for fuses with bolt down
mounting such as semi-conductor, high-speed
or industrial types (Classes J, T & L).
For protection where frequent outages are
common and there are low levels of available
fault current.
For maximum protection of motors,
controllers or panels.
For branch circuits in more general
applications where current limitation
requirements are lower.
