International Standards and Conformity Assessment for all electrical, electronic and related technologies



Reference EN 60252-1:2011
Title AC motor capacitors - Part 1: General - Performance, testing and rating - Safety requirements - Guidance for installation and operation
Project Number 22429
Abstract/Scope 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.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
