Directive 2014/35/EU of the European Parliament and of the Council of 26 February 2014 on the harmonisation of the laws of the Member States relating to the making available on the market of electrical equipment designed for use within certain voltage limits Text with EEA relevance
IEC 60252-1:2010 applies to motor capacitors intended for connection to windings of asynchronous motors supplied from a single-phase system having a frequency up to and including 100 Hz, and to capacitors to be connected to three-phase asynchronous motors so that these motors may be supplied from a single-phase system. This standard covers impregnated or unimpregnated capacitors having a dielectric of paper, plastic film, or a combination of both, either metallized or with metal-foil electrodes, with rated voltages up to and including 660 V. This edition includes the following significant technical changes with respect to the previous edition: – the definition of 'segmented capacitors' has been added in 3.6; – the definition of 'classes of operation' has been clarified, with the addition of the concept of 'probable life' with reference to statistics, in 3.9; – the following wording 'Operation above the rated voltage will reduce the life expectancy of the capacitor' has been introduced in 6.1. – some clarifications have been added to Clause 8, Marking, mainly for small capacitors.
