Product overview
The VS1 circuit breaker is independently developed by Knkong and adopts a modular mechanism. Compared with the traditional VS1 circuit breaker, it is easy to install, maintain, test and operate. It has higher operational stability, higher safety and longer service life. This product can meet the application needs of customers in 12kV and 24kV power transmission and distribution systems and is widely used to replace traditional European brands.
VS1-Series circuit breaker features high stability and high reliability
In terms of braking mechanisms, VS1 series vacuum circuit breakers have optimized transmission components. The modularization of the spring mechanism makes it easy to maintain, has short maintenance time for power failure, and strong versatility of parts. The colleague's vacuum interrupter has better compatibility and improved performance.
