IEC 61439-2:2011 defines the specific requirements of power switchgear and controlgear assemblies (PSC-ASSEMBLIES) as follows: – ASSEMBLIES for which the rated voltage does not exceed 1 000 V in case of a.c. or 1 500 V in case of d.c.; – stationary or movable ASSEMBLIES with or without enclosure; – ASSEMBLIES intended for use in connection with the generation, transmission, distribution and conversion of electric energy, and for the control of electric energy consuming equipment; – ASSEMBLIES designed for use under special service conditions, for example in ships and in rail vehicles provided that the other relevant specific requirements are complied with; – ASSEMBLIES designed for electrical equipment of machines. Supplementary requirements for ASSEMBLIES forming part of a machine are covered by the IEC 60204 series. This second edition cancels and replaces the first edition published in 2009. It constitutes a technical revision. This second edition includes the following significant technical changes with respect to the last edition of IEC 61439-2: – clarification of the scope; – revision of requirements for withdrawable and removable parts; – revision of mechanical impact test (10.2.6); – extension of Table 101; – review of Table BB.1 to reflect modified requirements and verifications; – general editorial review. This publication is to be read in conjunction with \/2.<\/p>\n
