IEEE C37.48:1987 (R1992)

New IEEE Standard - Superseded.
Superseded. Information on the application, operation, and maintenance of high-voltage fuses (above 1000 V), distribution enclosed single-pole air switches, fuse disconnecting switches, and accessories for use on AC distribution systems is provided. This guide is one of a series of complementary standards covering various types of high-voltage fuses and switches, so arranged that two of the standards apply to all devices while each of the other standards provides additional specifications for a particular device. For each device, IEEE Std C37.40-1993, IEEE Std C37.41-1994, plus the standard covering that device, constitute a complete set of standards for each device. In addition, IEEE Std C37.48-1997 is an application, operation, and maintenance guide for all the devices.

This guide applies to high-voltage fuses (above 600 V), distribution enclosed singlepole air switches, fuse disconnecting switches, and accessories for ac distribution systems as follows:
(1) Enclosed, open, and open-link types of distribution cutouts and fuses
(2) Distribution current-limiting fuses
(3) Distribution oil cutouts
(4) Distribution enclosed single-pole air switches
(5) Power fuses including current-limiting types
(6) Outdoor and indoor fuse disconnecting switches
(7) Fuse supports, fuse mountings, fuse hooks, fuse tongs, and fuse links, all of the type used exclusively with products listed in (1) through (6)
(8) Removable switch blades for products listed in (1) through (3).
