Superseded Standard

IEEE C37.37-1979

IEEE Loading Guide for AC High-Voltage Air Switches (in excess of 1000 volts)

Superseded The concepts of allowable continuous current, allowable continuous current class, and loadability factors are used to establish the criteria for designating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.
