Film Capacitors – Power Factor Correction

PhaseCap Premium capacitors

B25667C4237A375

MKK415-D-12.5-01/MKK440-D-14.2-01

These figures apply to the capacitor alone. Because the fixing and the terminals may influence the

vibration properties, it is necessary to check stability when a capacitor is built in and exposed to

vibration. Irrespective of this, you are advised not to locate capacitors where vibration amplitude

reaches the maximum in strongly vibrating equipment.

Mechanical protection

The capacitor has to be installed in a way that mechanical damages and dents in the aluminum can

are avoided.

Grounding

The threaded bottom stud of the capacitor has to be used for grounding. In case grounding is done

via metal chassis that the capacitor is mounted to, the layer of varnish beneath the washer and nut

should be removed. The maximum tightening torque is 10 Nm.

Maintenance

 Check tightness of the connections/terminals periodically.

 Take current reading twice a year and compare with nominal current. Use a harmonic analyser or

true effective RMS-meter.

 In case of current above the nominal current check your application for modifications.

 If a significant increase in the amount of non-linear loads has been detected, then a consultant

has to be called in for a harmonic study.

 In case of the presence of harmonics installation of a de-tuned capacitor bank (reactors) must be

considered.

 Check the discharge resistors/reactors and in case of doubt, check their function:

(1) Power the capacitor up and down.

(2) After ≤ 90 seconds the voltage between the terminals must decline to less than 75 V.

 Check the temperature of capacitors directly after operation for a longer period, but make sure

that the capacitors have been switched off. In case of excessive temperature of individual

capacitors, it is recommended to replace these capacitors, as this should be an indication for loss

factor increase, which is a sign for reaching end of life.

Storage and operating conditions

Do not use or store capacitors in corrosive atmosphere, especially where chloride gas, sulfide gas,

acid, alkali, salt or the like are present. In dusty environments regular maintenance and cleaning

especially of the terminals is required to avoid conductive path between phases and/or phases

and ground.

Note

For detailed information about PFC capacitors and cautions, refer to the latest version of EPCOS PFC

Product Profile.
