This part of IEC 61439 defines the specific requirements for the power switchgear and
controlgear assembly (abbreviated 'PSC-assembly' throughout this document see 3.1.101) as follows:
• assemblies for which the rated voltage does not exceed 1 000 V AC or 1 500 V DC;
• assemblies designed for a nominal frequency of the incoming supply or supplies not
exceeding 1 000 Hz;
NOTE 1 Frequencies above 1 kHz are considered as high frequencies, see also IEC 60664-1:2007, 5.3.3.2.5 to take into account additional constraints to insulation coordination.
• assemblies intended for indoor and outdoor applications;
• stationary or movable assemblies with or without enclosures;
• assemblies intended for use in connection with the generation, transmission, distribution and conversion of electrical energy, and for the control of equipment consuming electrical energy and for associated data processing;
• 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;
NOTE 2 Supplementary requirements for assemblies in ships are covered by IEC 60092-302-2.
