Power Capacitor

Power Capacitor FRAKO (Germany)

Specifications

Rated voltage 440Vac ~ 610Vac (1-Ph or 3-Ph).
Overload current (2x) rated current permanently,
(300x) rated current peak for short period.
Rated Frequency 50Hz / 60Hz
Rated Reactive Power 2.6kVAr ~ 26.9kVAr at 415V 50Hz
Tolerance ± 5%
Temperature Class -40 ~ +60 Degree Celsius
Typical Loss 0.2Watt/kVAr at Coils
Standards Conformance VDE0560, EN60831, IEC60831

Design And Construction

Cylindrical aluminium case with M12 x 12 stud for mounting and earthing.
Dielectric consists of self-healing, low-loss metallised polypropylene foil.
Dry type, filled with flame inhibiting, stabilized mineral filler.
Very compact construction. 15kVAr reactive power can be housed in 1000cm sq.
Equipped with over-pressure disconnection device in case of overload condition.
Equipped with maintenance-free spring tension connection terminals. Housed in moulded cap for safety protection.
1-Phase or 3-Phase capacitors with integrated discharge resistor. Discharge of 50VAC within 1 minute, which more than satisfy IEC831 requirement.

Applications

Especially suitable for Power Factor Correction and Tuned Filter applications due to the following properties:

  • Excellent voltage and current overload capacity. Upon careful selection of capacitor, overload current may be up to (3x) the rated current permanently.
  • Exceptional high life expectancy. Extreme purity of the material used prevents a deterioration of the loss factor and thereby a reduction of the dielectric strength and the current load capacity.
  • Safe reaction at overload and during possible breakdowns. Offers the highest possible standard of safety with an overload disconnector, which activates at internal overpressure, disconnects the capacitor from the mains and thereby prevents capacitor destruction.
