This part of IEC 60947 applies to switches, disconnectors, switch-disconnectors and fuse-combination units to be used in distribution circuits and motor circuits of which the rated voltage does not exceed 1 000 V a.c. or 1 500 V d.c.<\/p>\n

The manufacturer shall specify the type, ratings and characteristics according to the relevant standard of any incorporated fuses.<\/p>\n

This part does not apply to equipment coming within the scope of IEC 60947\u20112, IEC 60947\u20114\u20111 and IEC 60947\u20115\u20111; however, when switches and fuse-combination units coming into the scope of this part are normally used to start, accelerate and\/or stop an individual motor they shall also comply with the additional requirements given in Annex A.<\/p>\n

The requirements for single pole operated three pole switches are included in Annex C.<\/p>\n

Auxiliary switches fitted to equipment within the scope of this part shall comply with the requirements of IEC 60947\u20115\u20111.<\/p>\n

This part does not include the additional requirements necessary for electrical apparatus for explosive gas atmospheres.<\/p>\n

\n

NOTE 1 Depending on its design, a switch (or disconnector) can be referred to as “a rotary switch (disconnector)”, “cam-operated switch (disconnector)”, “knife-switch (disconnector)”, etc.<\/p>\n<\/blockquote>\n

\n

NOTE 2 In this part, the word “switch” also applies to the apparatus referred to in French as “commutateurs”, intended to modify the connections between several circuits and inter alia to substitute a part of a circuit for another.<\/p>\n<\/blockquote>\n

\n

NOTE 3 In general, throughout this part switches, disconnectors, switch-disconnectors and fuse-combination units will be referred to as “equipment”.<\/p>\n<\/blockquote>\n

The object of this part is to state<\/p>\n

    \n
  1. \n

    the characteristics of the equipment;<\/p>\n<\/li>\n

  2. \n

    the conditions with which the equipment shall comply with reference to<\/p>\n

    1. \n

      operation and behaviour in normal service;<\/p>\n<\/li>\n

    2. \n

      operation and behaviour in case of specified abnormal conditions, e.g. short circuit;<\/p>\n<\/li>\n

    3. \n

      dielectric properties;<\/p>\n<\/li>\n<\/ol>\n<\/li>\n

    4. \n

      the tests for confirming that these conditions have been met and the methods to be adopted for these tests;<\/p>\n<\/li>\n

    5. \n

      the information to be marked on the equipment or made available by the manufacturer, e.g. in the catalogue.<\/p>\n<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
