Features and Benefits
• Wide range of EEI-NEMA type fuse links for use in open fuse
cutouts
• Voltage ratings up to 27kV.
• Can be coordinated with other overcurrent protective devices
for sectionalizing to isolate feeder branches.
Typical Applications
• Medium Voltage Fused Cutouts
High-Surge Type H Fuses
High-surge, Type H fuses are manufactured in ratings of 1, 2,
3, 5, and 8A. They have been developed principally for prima-
ry fusing of small-sized transformers. Type H links are manu-
factured in the universal buttonhead design.
Type N Fuses
Type N fuses conform to previous NEMA standards and have
been superseded by Type K and T links. Type N fuses are
manufactured in the universal button design in ratings of 5
through 200A for use in NEMA standard dimensioned cutouts
rated through 27kV.
