FAQs

 

What is the main function of the CJ19 Contactors for Capacitor Switching?

The CJ19 is designed for connecting and disconnecting low-voltage capacitor banks, preventing inrush current and transient overvoltage during switching operations.

 

How does it protect capacitors from inrush current?

It integrates pre-charge resistors that momentarily connect during capacitor energization, limiting surge current and ensuring smooth capacitor engagement. 

 

What are the available current and voltage ratings?

The CJ19 series covers 25–170 A and operates up to 690 V, suitable for capacitor banks rated from 7.2 to 156 kvar.

 

How is the CJ19 different from standard AC contactors?

Unlike regular contactors, the CJ19 is specially designed with arc-resistant contacts and damping resistors, optimized for the AC-6b utilization category, ideal for capacitor circuits.

 

Where can it be used?

It is widely used in power factor correction panels, automatic capacitor compensation cabinets, and industrial power distribution systems requiring reliable reactive power control.
