IEEE C37.46

Abstract

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: <br>a) Power class expulsion-type fuses <br>b) Power class current-limiting type fuses <br>c) Power class fuse disconnecting switches <br>d) Item a) through item c) used in fuse-enclosure packages (FEPs) <br>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 <br>f) Disconnecting devices created by the use of a removable switch blade in a power class fuse support <br>g) Fuse links when used exclusively with power class fuses and fuse disconnecting switches <br><strong>Purpose</strong> <br>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.
