Product Description

1. General
VS1 type indoor high voltage vacuum circuit breaker is one of three phase 50Hz, 7.2 to 24 kV indoor high voltage switchgear, it is compliance with IEC6227:2003 and IEC56 < current high-voltage circuit-breaker>>(1987).
The VS1 type VCB manufactured by our company is of fifth generations product, it is with reliable interlock functions, suitable for frequent operation, also with many times of breaking and quick re-close capacity. The VCB consists of operating mechanism and arc-extinguish chambers in front-back arrangement, it can either be used as a fixed installation unit or as an individual VCB carriage together with a base-cart.
