41、 and fuse-combination units 1 General The provisions of the general rules dealt with in IEC 60947-1 are applicable to this part, where specifically called for. Clauses and subclauses, tables, figures and appendices of the general rules thus applicable are identified by reference IEC 60947-1, e.g., 4

42、.3.4.1 of IEC 60947-1, Table 4 of IEC 60947-1, or Annex A of IEC 60947-1. 1.1 Scope and object 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

43、 1 000 V a.c. or 1 500 V d.c. The manufacturer shall specify the type, ratings and characteristics according to the relevant standard of any incorporated fuses. This part does not apply to equipment coming within the scope of IEC 60947-2, IEC 60947-4-1 and IEC 60947-5-1; however, when switches and f

44、use-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. The requirements for single pole operated three pole switches are included in Annex C. Auxiliary s

45、witches fitted to equipment within the scope of this part shall comply with the requirements of IEC 60947-5-1. This part does not include the additional requirements necessary for electrical apparatus for explosive gas atmospheres. NOTE 1Depending on its design, a switch (or disconnector) can be ref

46、erred to as “a rotary switch (disconnector)“, “cam-operated switch (disconnector)“, “knife-switch (disconnector)“, etc. NOTE 2In 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 a

47、lia to substitute a part of a circuit for another. NOTE 3 In general, throughout this part switches, disconnectors, switch-disconnectors and fuse-combination units will be referred to as “equipment“. The object of this part is to state a) the characteristics of the equipment; b) the conditions with

48、which the equipment shall comply with reference to 1) operation and behaviour in normal service; 2) operation and behaviour in case of specified abnormal conditions, e.g. short circuit; 3) dielectric properties; c) the tests for confirming that these conditions have been met and the methods to be ad

49、opted for these tests; BS EN 60947-3:2009 60947-3 IEC:2008 7 d) the information to be marked on the equipment or made available by the manufacturer, e.g. in the catalogue. 1.2 Normative references The following referenced documents are indispensable for the application of this document.
