General Information:
• Compact branch-circuit units with high interrupting rating
and current-limitation.
• With 600V rating, they can be used in 120/208, 120/240
and 277/480V circuits.
• Length variations relative to case size make the “rejec-
tion” type fuses.
• In general, SC fuses are about ⁄Ω£ the size of the 600V
NEC fuse type.
• SC fuses with ampere ratings above 6A have a
degree of overload time-delay which permits them to
pass temporary overloads. At 200% load, they have a
minimum opening time of 12 seconds.
