Reliable Capacitor Switching for Power Factor Correction

Capacitor contactors such as the CHINT CJ19 series are specifically designed for switching capacitor banks used in reactive power compensation systems. Unlike standard contactors, they incorporate pre-charge resistors to limit high transient currents generated when capacitors are energised. This significantly reduces contact wear and improves system reliability.

The CJ19 range is widely used in automatic power factor correction panels and industrial electrical distribution systems where reliable capacitor switching and stable reactive power compensation are essential for improving overall power quality and reducing energy penalties.

Typical Applications

• Automatic power factor correction panels.
• Reactive power compensation systems.
• Industrial electrical distribution boards.
• Capacitor bank switching systems.
• Commercial building power management systems.
• Industrial automation and energy efficiency projects.
