VI for Low-voltage VCB

The rated voltage of vacuum interrupter for low-voltage circuit breaker is ≤ 1500 V, which is mainly used in special application fields with strict requirements, such as: In distributed wind power generation and solar power generation, which requires frequent operation and extremely long service life; In chemical and mining fields, it is required to have safety and explosion-proof functions; In the field of naval ships, it is required to have the ability of breaking fault current for many times. The air switch commonly used in these fields can not meet the requirements, and the low-voltage vacuum circuit breaker is the best choice.
