Features:

short-circuit protection

overloads

single-phasing on three-phase systems

(selective coordination)

subject to temporary motor overloads and surge

currents to provide both high performance

short-circuit and overload protection

against low level overcurrent of overloads

and will hold an overload which is five times

greater than the ampere rating of the fuse for a

minimum of ten seconds
