This standard is applicable to ac circuit switchers designed for outdoor installation and for rated power frequencies of 50 Hz and 60 Hz and rated maximum voltages of 15.5 kV through 245 kV. It is applicable only to three-pole circuit switchers for use in three-phase systems. This standard is also applicable to the operating devices of circuit switchers and to their auxiliary equipment.
The proposed standard is being written to aid both manufacturers and users a standard in the design and selection of this widely used protective/switching device. It will establish the rating basis, preferred ratings, & test procedures. This standard is being written in a format that is compatible and acceptable to IEC standard users and is expected to adopted by that organization in our harmonization efforts. The document does not contain a purpose clause.
