1.1 Scope This standard covers ac switches rated above 1 kV up to and including 52 kV for use in metal-enclosed switchgear. These switches may be: a) Stationary or drawout b) Manual or power operated c) Fused or unfused Within this standard, the words "switch(es)" shall be considered to mean three-phase, ac, gang-operated, switch(es) as defined by this scope. These switches are intended to be installed in an enclosure that provides a degree of protection to the switch and the enclosure may be suitable for indoor or outdoor conditions and complies with the requirements of switchgear assemblies as defined by IEEE Std C37.20.2, IEEE Std C37.20.3, or IEEE Std C37.20.9. This standard does not apply to switches for use in subsurface or pad-mounted switchgear in IEEE Std C37.74 or to high-voltage air switches in IEEE Std C37.30.1.

C37.20.4-2013
IEEE Standard for Indoor AC Switches (1 kV to 38 kV) for Use in Metal-Enclosed Switchgear
Indoor ac medium-voltage switches for use in enclosures for application in power circuits at voltages above 1 kV through 38 kV are covered in this standard. Stationary or drawout, manual or power operation, and fused or unfused are included.
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
