CVS Sealed pole vacuum circuit breakerDetailed product description：

1、 Significant features:
CVSl vacuum circuit breaker is equipped with CG68 spring mechanism or CG69 permanent magnet mechanism, which is an independent integral mechanism
Simple structure with few components,
Compact structure, small volume, and light weight;
Fully functional and highly reliable,
The distribution of operation buttons and status indicators is neat and centralized;
Easy maintenance:
During maintenance, the entire mechanism can be replaced and repaired,
Parts can also be replaced and repaired on the circuit breaker.

2、 The latest SIEMENS vacuum arc extinguishing chamber technology
Low cut-off value, low contact resistance,
High mechanical and electrical lifespan, with minimal contact wear during the lifespan
Longitudinal magnetic field contact

3、 Sealed main circuit
The vacuum arc extinguishing chamber is vertically sealed inside an insulating cylinder to prevent damage to the 1G vacuum extinguishing chamber caused by external factors
Flexible sealing materials can reduce the impact of circuit breaker operation vibration on vacuum arc extinguishing chambers
Effectively blocking the creepage on the surface of the vacuum extinguishing chamber, reducing its volume.

4、 Coordination between operating mechanism and vacuum arc extinguishing chamber
Using PRO-E kinetic analysis and calculation, verified through experiments. With this cooperation, the contact burns are minimal
Compact structural design
The circuit breaker has few components, a reasonable and compact structural layout, and the coordination between the operating mechanism and the vacuum arc extinguishing chamber

5、 CVS solid sealed pole vacuum circuit breaker has a wide range of applications
The circuit breaker can be applied to various mid mounted removable switchgear such as KVN28 and KYN79, and can also be fixedly installed.
