CJ19 series contactors are specifically designed for switching capacitor banks in power factor correction systems, featuring pre-charge resistors and early-make contacts to limit inrush current.
Capacitor switching produces high inrush currents (up to 100x rated). Standard contactors would weld contacts. CJ19 series includes damping resistors that pre-charge capacitors before main contacts close.
We offer CJ19 series in 43A, 63A, 115A, and 170A ratings for capacitor bank switching in low voltage power factor correction systems.
Electrical life depends on switching frequency. Under normal PFC operation (few cycles per day), CJ19 contactors last 5+ years. For high-frequency switching, consult our application engineering team.
Yes, they work seamlessly with all major PFC controller brands, accepting standard control signals for automatic capacitor bank switching based on power factor measurement.
They comply with IEC 60947-4-1 and GB/T 14048.4, carrying CE certification for capacitor switching applications.
