Product Details

Product Overview

The CHSK series of capacitor fast-switching switches is specifically designed for dynamic, rapid compensation of 0.4kV power capacitors, making it ideal for applications involving inrush loads—such as welding machines, rolling mills, port cranes, elevators, and frequency conversion furnaces. These fast-switching devices operate with exceptional speed, featuring a response time of just 10 to 20 milliseconds. They connect at the voltage zero-crossing point and disconnect at the current zero-crossing point, ensuring no inrush currents are generated. As such, they represent an indispensable alternative to conventional AC contactors and hybrid switching solutions.
