- Scope
- This standard applies to AC disconnectors and grounding switches designed to be installed indoors and outdoors and operating at a frequency of 50 Hz and a nominal voltage of 3 000 V and above, with closed and open terminals. This standard also applies to the operating mechanisms 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 GB 3906, GB 7674 and IEC 62271-201.
