IEEE C37.42 – IEEE Standard Specifications for High-Voltage (>1000 V) Fuses and Accessories

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.
