Technical data
Application FRAKO capacitors allow power factor correction installations to be constructed for any requirement and meet the regulations of VDE 0560 part 46,47, EN 60831-1 and -2 as well as IEC 831-1 and 2. FRAKO holds the Management System Certificate ISO 9001 and the Environmental Management System Certificate ISO 14001. Mechanical Construction Cylindricalaluminium case, dielectric consisting of metallized polypropylene foil. Dry type, filled with a flame inhibiting, stabilized mineral filler. The dielectric is self-healing. In case of a breakdown caused, for example, by voltage overload, the self-healing effect takes place. If the self-healing process does not operate (e.g. because of voltage, current or thermal overload) the cover plate, which isdesigned as an overload valve, is raised and ruptures the internal connecting wires to the coils, so that the capacitor is disconnected from the mains. Design Cylindrical aluminium case, with mounting stud M 12 x 12. Three-phase capacitors with integrated discharge resistor. Rating 2.5 – 30 kVar at 400V / 50 Hz Capacitance and Rating Tolerance +/- 5 % Power Loss Approx. 0.05 % (0.5 Watt/kVar)measured at the connecting terminal including discharge resistors. Approx. 0.02 % (0.2 Watt/kVar) measured at the capacitor coils. Temperature Class - 40 °C to + 60 °C Overload capacity See next page Discharging According to IEC 831, every power capacitor must have a discharge device which guarantees a discharge to 75 VAC within three minutes. FRAKO capacitors have integrated discharge resistors whichguarantee a discharge to 50 VAC within one minute. Accessories All capacitors with index D52 can be equipped with a connecting terminal in tension spring method against surcharge. All capacitors up to diameter 70 mm can be equipped with a plastic cap and rubber sleeve against surcharge. LKT Capacitors
