Superseded The concepts of allowable continuous current, allowable continuous current class, and loadability factors are used to establish the criteria for designating the load-current carrying capabilities of air switches over a range of ambient temperatures. This is accomplished through a family of loadability factor curves. The loadability factors are also presented in tabular form.

C37.37-1996
IEEE Loading Guide for AC High-Voltage Air Switches (in Excess of 1000 V)
An aid to users to determine (1) the allowable continuous current class (ACCC), (2) the continuous load current capabilities of air switches under various conditions of ambient temperature, and (3) the emergency load current capabilities of air switches under various conditions of ambient temperature, is provided. This guide does not apply to switches used in enclosures covered by IEEE Std C37.20.2-1993, IEEE Std C37.20.3-1996, IEEE Std C37.23-1987, IEEE Std C37.71-1984, and ANSI C37.72-1987. (Superseded by IEEE Std C37.30.1-2011)
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No Inactive-Withdrawn Standards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
