IEC 61439-2:2020 defines the specific requirements for the power switchgear and controlgear assembly (abbreviated \u2018PSC-assembly\u2019 throughout this document see 3.1.101) as follows: <\/p>\n
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. <\/p>\n
NOTE 2?Supplementary requirements for assemblies in ships are covered by IEC 60092-302-2. This third edition cancels and replaces the second edition published in 2011. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: <\/p>\n
