Anotace

IEC 60092-302-2:2025 defines the specific requirements of low voltage marine power switchgear and controlgear assemblies (mpsc-assemblies) as follows: - stationary assemblies with enclosure for which the rated voltage does not exceed 1 000 V AC or 1500 V DC; - assemblies intended for use in conjunction with the power generation, distribution and conversion of electric energy, and for the control of electric energy consuming equipment. Due to the marine application and the risks associated with loss of power, additional safety factors have been applied to minimise the risk of failure, such as applying an additional safety factor on clearance distances. This document applies to all assemblies whether they are designed, manufactured and verified on a one-off basis or fully standardised and manufactured in quantity. Either the manufacture or assembly, or both, of the MPSC assembly can be carried out by others than the original manufacturer. This document does not apply to individual devices and self-contained components, such as motor starters, fuse switches, electronic equipment, which comply with the relevant product standards. This second edition cancels and replaces the first edition published in 2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) amended and updated in line with, and correctly referenced to the updated clauses of IEC 61439-1:2020 and IEC 61439-2:2020; b) explanation of the need to special consideration for marine applications added; c) Figure 201 updated; d) adjustment has been made to the "safety factors" for creepage and clearance distances.
