New IEEE Standard - Active.
Specifications for high voltage (above 1000 volts) Class A and Class B expulsion and current-limiting fuses. This includes: a) Expulsion type Class A [distribution class] fuses, fuse cutouts, fuse disconnecting switches, their associated fuse links or refill units, disconnecting cutouts, and accessories for these devices with rated voltages from 1 through 38 kV. b) Expulsion type Class B [power class] fuses, fuse disconnecting switches, their associated fuse links or refill units, disconnecting cutouts, and accessories for these devices with rated voltages from 1 through 170 kV. c) Class A and Class B current-limiting fuses and accessories for these devices with rated voltages 1 through 38 kV. d) Distribution and power class expulsion, current-limiting, and combination-type external capacitor fuses and accessories, with rated voltages from 1 kV through 38 kV, for protecting shunt capacitors complying with IEEE Std 18 and NEMA CP 1. e) Any of the above devices used in fuse enclosure packages. f) All of these devices are intended for use on alternating current distribution systems. This standard also supersedes IEEE C37.43-2008, IEEE C37.46-2010 and IEEE C37.47-2011.
This standard establishes specifications 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
j) Accessories including mounting brackets and switch stick (switch hooks)
This standard may also be used for other devices that are similar to the devices listed in the scope.
Standard specifications for the devices covered by this document are necessary to assure consistent development and application of these devices by manufacturers and users of these devices.
