Product Description

 

Indoor HV Vacuum Circuit Breaker 
 

Product Description
VS1 indoor medium voltage Vacuum Circuit Breaker is a three-phase AC 50Hz ,rated voltage 6KV,12KV,24KV switch equipment of power system.

Breaker adopts the integral design of the actuating mechanism and the breaker body, which can be used as a fixed installation unit or as an individual VCB carriage together with handcart. They have a long life expectancy. There is no adverse effect on the vacuum, even from frequent switching of operating and short-circuit currents.

Features
1 - with reliable interlock functions, suitable for frequent operation
2 - low noise and energy consumed
3 - simple and robust construction.
4 - high operating reliability
5 - mechanical durability of switch : 20000 times, etc

 
Fields of application

1 - Transformers and distribution substations
2 - Generator control and protection

3 - Capacitor bank control and protection, etc
