CJ19(16)-25, 32, 43, 63, 85, 95 Switching capacitor contactors, specifically designed for switching low-voltage parallel capacitors, are widely used in reactive power compensation equipment with AC 50Hz and voltage up to 380V. The contactors are equipped with a surge current suppression device, which can effectively reduce the impact of closing surge current on the capacitors and lower the operational overvoltage at the moment of disconnection. They can replace the original switching device consisting of one contactor and three current-limiting reactors. They have a small size, light weight, strong switching capability, and are easy to install.

Product Features
Current-Limited Resistor Design
This feature incorporates a built-in current-limiting resistor within the contactor to effectively suppress inrush currents during switching operations. By mitigating high transient currents at startup, it prevents potential damage to capacitors and associated components, thereby enhancing system reliability, extending equipment lifespan, and reducing maintenance costs. This is critical in capacitor switching applications where sudden voltage surges can lead to malfunctions or failures.

Direct-Acting Double-Break Structure
The contactor employs a direct-acting mechanism with a double-break contact system, ensuring swift and precise disconnection of circuits. This robust design enables flexible manual operation for easy inspection and maintenance, allowing technicians to safely test or reset the device without full shutdown. It enhances operational efficiency by providing reliable arc-quenching performance and minimizing contact wear, which is essential for frequent switching in capacitor banks or reactive power compensation systems.
Insulated Terminal Boot for Safety
Integrated with insulating boots on all connection terminals, this feature delivers a high level of electrical safety by preventing accidental contact and exposure to live parts. The insulating material acts as a barrier against electrical shocks and short circuits, ensuring secure installations even in confined or damp environments. This reduces the risk of personnel injuries and equipment damage, meeting international safety standards such as IEC 60947, which is vital for industrial and commercial power distribution networks.
Flexible Mounting Solutions
Offering versatile installation options, the contactor can be securely attached via screw fastening or directly mounted onto busbars, adapting to diverse panel configurations. This flexibility simplifies integration into low voltage switchgear systems like XL-21, GGJ, or APFC cabinets, accommodating space constraints without compromising stability. It streamlines the installation process, reduces wiring complexity, and supports seamless upgrades in both new and retrofit projects, optimizing overall cost-effectiveness.
