IEEE C37.46-2010

This standard establishes specifications for high-voltage (above 1000 V) expulsion and current-limiting type power class fuses, and accessories. All of these devices are intended for use on alternating current systems. These specifications apply to the following specific types of equipment: a) Power class expulsion type fuses b) Power class current-limiting type fuses c) Power class fuse disconnecting switches d) Item a) through item c) used in fuse enclosure packages e) Fuse supports, fuse-holders, fuse hooks, fuse units, and refill units, of the type intended for use with power class fuses and fuse disconnecting switches f) Disconnecting devices created by the use of a removable switch blade in a power class fuse support g) Fuse links when used exclusively with power class fuses and fuse disconnecting switches.
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.
New IEEE Standard – Superseded. Specifications for high-voltage (above 1000 V) expulsion and current-limiting type power class fuses, fuse disconnecting switches, their associated fuse links, disconnecting cutouts, and accessories for these devices are covered. All of these devices are intended for use on alternating-current distribution systems. (This standard is superseded by IEEE C37.42-2016 and supersedes IEEE C37.46-2001)
