IEEE C37.45:2007

New IEEE Standard - Superseded.
Specifications for high-voltage (above 1000 volts) distribution class enclosed single pole air switches and associated accessories with rated voltages from 1 kV through 8.3 kV are established. All of these devices are intended for use on alternating current distribution systems. These include distribution class enclosed single-pole air switches, supports, mountings, fuse hooks, and tongs, all of the type used exclusively with distribution class enclosed single-pole air switches, and distribution class enclosed single-pole air switches used in enclosure packages.

This standard establishes specifications for high-voltage (above 1000 V) distribution class enclosed singlepole
air switches and associated accessories with rated voltages from 1 kV through 8.3 kV. All of these
devices are intended for use on alternating current distribution systems. These specifications apply to the
following specific types of equipment:
Distribution class enclosed single-pole air switches
Supports, mountings, fuse hooks, and tongs, all of the type used exclusively with distribution
class enclosed single-pole air switches
Distribution class enclosed single-pole air switches used in enclosure packages
This standard is a revision of American National Standard Specifications for Distribution Enclosed Single-Pole Air Switches, ANSI C37.45-1981(R1992), to bring it up to date and in line with present day requirements for high-voltage switches. This standard was previously developed by the NEMA High Voltage Fuse Technical Committee (SG2). As of 2003 the responsibility for this standard has been transferred to the IEEE High-Voltage Fuse Subcommittee. Liaison was maintained with the International Electrotechnical Commission (IEC) during the development of the revisions in order to incorporate the latest thinking up to the time of publication.
