Power Factor Correction Capacitors
 Design
FRAKO Power Factor Correction Capacitors are available as three-phase capacitors in 3 versions: Basic, Standard and Premium. The single-phase capacitors are available as Standard version.
Rating
1.1 -SOkvar; 300 -610V; 50/60 Hz (higher voltages on request!)
Capacitance and Rating Tolerance
+/-5%
Power Loss
Approx. Q.5Watt/kvar measured at the connecting terminal including discharge resistors. Approx. 0-2YVatt/kvar measured at the capacitor coils.
Temperature Class
upto-40°C;+65°C
Discharging
According to EN 60831, every Power Factor Correction Capacitor must have a discharge device which guarantees a discharge to 75V within 3 minutes as a protection against electric shock. All FRAKO capacitors have integrated discharge resistors which guarantee a discharge below 50V within one minute.

Technical Remarks
For the operation of Power Factor Correction Capacitors three aspects are of utmost importance:
High overload capacity
Long life expectancy
Safe reaction at overload |
Life Expectancy
The use of thoroughly tested material as well as careful processing ensures quality and a long life expectan¬cy of the products. FRAKO produces its capacitors according to own specifications, which surpass by far the requirements of EN 60831-1/2. Quality tests following each single manufacturing step, verify an outstanding manufacturing quality. Combined with a unique capacitor manufacturing technology, FRAKO achieves a worldwide leading durability.
For example, the consistently low power loss over many years is achieved by using a special mineral filler and stabilizer which can avoid permanent partial discharges within the dielectric. Vacuum drying and tem¬perature storage over several days avoid oxygen inclusion, which would accelerate the aging process of a capacitor. This means an extra effort in our production which, however, pays-off with a longer life expectancy |
Safety Features
FRAKO Power Factor Correction Capacitors operate with triple safety:
Self-healing at over-voltage
Reliable in operation because of segmented film
An overpressure disconnector disconnects the capacitors from the mains at the end of their lifetime or at dangerous overload |
