This part of IEC 62271 specifies requirements for internal arc classification of metal-enclosed pole-mounted switchgear installations used for alternating current with rated voltages above 1 kV and up to and including 52 kV with service frequencies up to and including 60 Hz. This document is applicable to three-phase, two-phase and single phase equipment. Enclosures may include fixed and removable components and may be filled with fluid (liquid or gas) to provide insulation.
NOTE For the use of this document high-voltage (IEC 60050-601:1985, 601-01-27) is the rated voltage above 1 000 V. However, medium voltage (IEC 60050-601:1985, 601-01-28) is commonly used for distribution systems with voltages above 1 kV and generally applied up to and including 52 kV; refer to [1] of the Bibliography.
This document does not preclude that other equipment may be included in the same enclosure. In such a case, any possible influence of that equipment on the switchgear and controlgear is to be taken into account.

System referencing conductor switching device
Käsitlusala:
This standard applies to a system referencing conductor switching devices (SRCSD) for household and similar uses within a Prosumer’s Electrical Installations (PEI).The SRCSD provides functions as described in clause 82.8.2.2.4 of IEC 60364-8-82 Ed1.
PEI intended for operating either being connected to a distribution network or being disconnected from the distribution network is an islandable PEI.
Intentional disconnection from and connection to the distribution network relies on the local earthing system being switched by the SRCSD. In addition, unintentional loss of distribution network is covered.
The SRCSD is a single pole device intended to connect one live conductor of the power system to an earthing arrangement.
In general the neutral conductor is earthed.
Switching the SRCSD can change the local type of system earthing, if types of system earthing are different in island and grid connected modes.
The system referencing conductor switching device (SRCSD) is interlocked with the switching device for islanding (SDFI) of a Prosumer electrical installation.
SRCSD can be integrated in a device with other function e. g. with a SDFI.
NOTE 1. see also IEC 60364-8-82 ED1.
This standard applies to SRCSD for rated voltages not exceeding 440 V AC with rated frequencies of 50 Hz, 60 Hz or 50/60 Hz.
NOTE 2. SRCSD for DC operations is under consideration.
The requirements of this document apply for standard environmental conditions. They are applicable to SRCSD intended for use in an environment with pollution degree 2 and overvoltage categories III according to IEC 60664-1:2020. SRCSD have at least a degree of
protection IP 20 according to IEC 60529. Additional requirements can be necessary for devices used in locations having more severe environmental conditions.
