IEC 60252-1 Ed. 2.1 b – AC motor capacitors – Part 1: General – Performance, testing andrating – Safety requirements – Guidance for installation and operation CONSOLIDATED EDITION
IEC 60252-1:2010+A1:2013 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. This consolidated version consists of the second edition (2010) and its amendment 1 (2013). Therefore, no need to order amendment in addition to this publication.
