This part of IEC 62271 applies to alternating current disconnectors and earthing switches,
designed for indoor and outdoor enclosed and open terminal installations for voltages above
1 000 V and for service frequencies up to and including 60 Hz.
It also applies to the operating devices of these disconnectors and earthing switches and their
auxiliary equipment.
Additional requirements for disconnectors and earthing switches in enclosed switchgear and
controlgear are given in IEC 60298, IEC 60466 and IEC 60517.
