Vacuum circuit breaker is a power distribution device mainly applied for breaking load current, overload current and fault current in the application of industrial and mining enterprises, power plants, substations, etc. Indoor vacuum circuit breaker is the core device of distribution equipment, which is mainly used for vacuum switchgear. Outdoor VCB/recloser is mainly applied in rural or suburban distribution networks to break, close, and carry line load current, overload current and fault current.
