Scope and object

This part of IEC 60252 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 are 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 1 000 V nominal voltage (see IEC 60831-1);

- shunt capacitors of non-self-healing type for a.c. power systems of up to and including 1 000 V nominal voltage (see IEC 60931-1);

- shunt capacitors for a.c. power systems having a nominal voltage above 1 000 V (see IEC 60871-1);

- capacitors for induction heat-generating plants, operating at frequencies between 40 Hz and 24 000 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);

- 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 guidance for installation and operation.
