This International Standard 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. Motor start capacitors will be covered by IEC 60252-2. NOTE The following are excluded from this standard: - shunt capacitors of the self-healing type for a.c. power systems of up to and including 1000 V nominal voltage (see IEC 60831-1); - shunt capacitors of non-self-healing type for a.c, power systems of up to and including 1000 V nominal voltage (see IEC 60931-1); - shunt capacitors for a.c. power systems having a nominal voltage above 1000 V (see IEC 60871-1); - capacitors for induction heat-generating plants, operating at frequencies between 40 Hz and 24000 Hz (see IEC 60110-1); - series capacitors (see IEC 60143); - coupling capacitors and capacitor dividers (see IEC 60358); - capacitors to be used in power electronic circuits (see IEC 61071-1); - small a.c. capacitors to be used for fluorescent and discharge lamps (see IEC 61048); - capacitors for suppression of radio interference (IEC publication under consideration); - capacitors intended to be used in various types of electrical equipment and thus considered as components; - capacitors intended for use with d.c. voltage superimposed on a.c. voltage. The object of this standard is a) to formulate uniform rules regarding performance, testing and rating; b) to formulate specific safety rules; c) to provide a guide for installation and operation. note: * AC motor capacitors - Part 2, Motor start capacitors. In preparation. This will become the standard for both self-healing and electrolytic motor start capacitors.
