E62-3HF with CAPAFIX™ and CAPASTUD™ terminals - the perfect AC Capacitor for High Frequency Filters

E62-3HF answers the growing demand for single and three-phase AC capacitors that can withstand AC currents in the kHz range. With their high AC load capacity, they are 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, a.m.o.

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. 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.

CAPAFIX™ is the new name of our optimized low-loss TORX terminals which can operate safely even at very high frequencies. They are also preferred by some as a flat alternative to the traditional, taller CAPAGRIP™ terminal of the E62-3ph series. The two sizes of CAPAFIX™ – Z3 (up to 39A per phase) and S4 (up to 56A/phase) – are complemented by the robust CAPASTUD™ with M10 studs that can withstand up to 100A per phase.

Both CAPAFIX™ terminals can be completed with an optional snap-on cover for protection from accidental contact (similar to IP10).
