The E62-3ph capacitors stand out by their high AC-voltage load capacity. They were designed especially for heavy duty operation in extreme or sophisticated operating conditions, such as AC filtering and power factor correction in wind power and UPS applications, harmonic filtering in three-phase mains with high or unusual levels of harmonic distortion in the frequency range up to 1 kHz.
Thanks to their construction, they have a very low series resistance and a small self-inductance. Our basic design principle - preferring short winding elements with comparably large diameters - as well as the use of wavecut technology in many models, serves for high rms and surge current strength.
The three capacitor elements are connected in delta internally; the plant oil filling is environmentally friendly and serves for optimized heat dissipation and improved internal insulation. As an E65-3ph option, they can also be filled with neutral insulation gas (Nitrogen). The finger-proof CAPAGRIP™ screw terminals (rated IP20) make for simple and reliable connections and easy addition of IP20-resistors or reactors for discharge.
The standard design has a long-term stable capacitance with ± 5% tolerance. Tighter tolerances are available on request.
Very good self-healing characteristics and the integrated overpressure protection (" BAM ") ensure safe operation and controlled disconnection in the event of overload or failure at the end of operating life.
