ELCO 3 Phase Cylindrical 705 Series - 525V (HEAVY DUTY)

ELCO 3 Phase Cylindrical 705 Series - 525V (HEAVY DUTY)

The 705 Series Cylindrical Power Capacitor is designed for power factor correction in motors, low-voltage transformers, and industrial switchboards.

This low-voltage capacitor is optimized for applications where superior power factor correction is essential and minimizing harmonic distortion is a priority. With a Total Harmonic Distortion Voltage (THDv) of ≤ 3% and a Total Harmonic Distortion Current (THDi) of < 30%, or 25% without detuned reactors / series reactors.  It ensures high-quality performance in sensitive systems.

Built for both low-voltage systems up to 525V, this capacitor is ideal for industries with significant inductive loads, such as motors, compressors, and pumps. It is particularly effective in environments with voltage fluctuations or harsh conditions, improving system efficiency by reducing reactive power and helping to avoid penalties.

The capacitor is also well-suited for renewable energy systems (solar, wind) and smart grids. It is compatible with harmonic filters in detuned circuits and is especially beneficial in regions with unstable or high voltage levels.

In environments with elevated harmonic distortion (above 5%), it is recommended to pair the capacitor with detuned reactors or harmonic filters. This combination ensures reliable operation and prevents premature failure due to harmonic overloads.
