This part of IEC 62271<\/span> <\/span> applies to AC switchgear and controlgear designed for indoor and\/or outdoor installation and for operation at service frequencies up to and including 60 Hz and having rated voltages above 1 000 V.<\/p>\n

This document applies to all high-voltage switchgear and controlgear except as otherwise specified in the relevant IEC standards for the particular type of switchgear and controlgear.<\/p>\n

\n
\n NOTE\n <\/div>\n

For the use of this document, high-voltage is defined as the rated voltage above 1 000 V. However, the term medium voltage is commonly used for distribution systems with voltages above 1 kV and generally applied up to and including 52 kV.<\/p>\n<\/div>\n
