Features:
• Compact branch-circuit units with high interrupting rating
and current-limitation
• With up to a 600V rating, they can be used in 120/208V,
120/240V and 277/480V circuits
• Size rejection by length helps prevent overfusing
• In general, SC fuses are about
1
⁄
2
the size of the 600V NEC
®
fuse type
• SC fuses 7 amps and above have a degree of overload
time-delay which permits them to pass temporary overloads
