This standard establishes specifications for high-voltage (>1000 V) distribution class current-limiting type fuses and associated accessories. All of these devices are intended for use on alternating current (ac) systems. These specifications apply to the following specific types of equipment: a) Distribution class current-limiting type fuses and fuse units b) Distribution class current-limiting fuse disconnecting switches c) Item a) and item b) used in fuse-enclosure packages d) Fuse supports, fuse units, refill units, and fuse mountings of the type intended for use with distribution class current-limiting type fuses, and fuse disconnecting switches. e) Disconnecting devices created by the use of a removable switch blade in a distribution class current-limiting type fuse support.
Standard specifications for the devices covered by this document are necessary to maintain consistent development and application of these devices by manufacturers and users of these devices.
New IEEE Standard – Superseded. Specifications for high-voltage (>1000 V) distribution class current-limiting fuses and fuse disconnecting switches, and associated accessories for these devices, are covered. All of these devices are intended for use on alternating-current distribution systems. (Superseded by IEEE C37.42-2016)
