This guide provides basic information about IEC low voltage motors that operate at voltages less than 1 000 V and produce a maximum power of 1000 kW.The IEC 61439 – the new IEC standard series - is available for low-voltage switchgear and control gear assemblies. The IEC 61439 series replaces the old IEC 60439 standard series following dissatisfaction over the uses of the series which were lacking in several areas.International Electrotechnical Commission (IEC) standard IEC/EN 60034-30:2008 defines energy-efficiency (IE code) classes for single speed, three-phase, 50 and 60 Hz induction motors. The standard is part of an effort to unify motor testing procedures .The International Electrotechnical Commission (IEC) standard IEC 61140:2016 defines Low voltage as 0 to 1000 V AC RMS or 0 to 1500 V DC. [1]
Low-voltage switchgear and controlgear assemblies - Part 1: General rules. IEC 61439-1:2020 lays down the general definitions and service conditions, construction requirements, technical characteristics and verification requirements for low-voltage .International Standard IEC 60038, IEC standard voltages, defines a set of standard voltages for use in low voltage and high voltage AC and DC electricity supply systems.
The minimum value measured must be according to standard IEC 61439-1 at least 1000 Ω/V with reference to the nominal voltage in relation to the earth of the circuit being tested. In practice, a target value of at least 0.5 MΩ should be used for 230/400 V assemblies and at least 1 MΩ above that. Using the methods of standard to design and test a switchboard avoids such problems as dielectric failure, reduced creepage or clearance, and other electrical safety risks. On the rare occasions that lightning strikes nearby, this can significantly increase the .
