Description / Abstract:
This standard specifies design test requirements for high-voltage (above 1000 V) fuses and accessories for use on ac electrical distribution systems. Devices with rated maximum voltages to 170 kV are covered. The devices to which this standard applies are as follows:
a) Expulsion fuses (including fuse cutouts)
b) Current-limiting fuses
c) Items a) and b) used in fuse-enclosure packages
d) Fuse supports of the type intended for use with fuses and fuse disconnecting switches
e) Disconnecting devices (fuse disconnecting switches, disconnecting switches, and disconnecting cutouts) created by the use of a removable fuse unit or switch blade in a fuse support
f) Expulsion, current-limiting, and combination types of external capacitor fuses used with a capacitor unit, a group of units, or capacitor banks
g) Backup current-limiting fuses (“motor-starter fuses”) used in conjunction with high-voltage motor starters
h) Fuse links when used exclusively with expulsion fuses and fuse disconnecting switches
i) Items a) through f) having integral load-break means
