    Abstract - (Show below) - (Hide below)

    Applies to automatic transfer switching equipment to be used in emergency power systems with interruption of the supply to the load during transfer, the rated voltage of which does not exceed 100 V a.c. or 1500 volt a.c. Specifies characteristics of equipment, conditions with which the equipment must comply, tests intended to confirm these conditions have been met and data to be marked on the equipment and/or provided by the manufacturer. This Standard is identical with and has been reproduced from IEC 60947-6-1:1989 plus Corrigendum:1991 plus Amendment 1:1994 and Amendment 2:1997.

    Scope - (Show below) - (Hide below)

    This standard applies to Automatic Transfer Switching Equipment (ATSE) to be used in emergency power systems with interruption of the supply to the load during transfer, the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c. It covers ATSE provided with or without an enclosure.Devices necessary for the control (e.g. control switches, ...) and the protection (e.g. circuit-breakers, ...) of an ATSE shall comply with the requirements of the relevant IEC standards.ATSE used only for emergency lighting may be subject to specific rules and/or legal requirements and are not, therefore, covered by this standard.
