VTV series vacuum circuit breaker is newly developed by ourselves. It embodies our ideas: compact, intelligent, environmental-friendly, energy-efficient and maitenance-free.
VTV series have wider application,such as power grid, power plant, petrochemical engineering, coal industry, metallurgy, railway and airport transportation system.
Its mechanical life can up to 60000 operations. It can be added with intelligent unit to be an intelligent vacuum circuit breaker.
It is applied in three-phase AC power system with rated voltage 7.2~40.5kV and 50/60Hz frequency
It is used to control and protect the electric equipments in places where frequent operation at rated current or multi-breaking short circuit current is needed.

We can supply whole solutions for VCB up to 40.5KV.
