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.
