Indoor Vacuum Circuit Breaker
VS1 series indoor high voltage vacuum circuit breaker
overview
VS1-12 indoor high-voltage vacuum circuit breaker is an indoor switchgear for a three-phase AC 50Hz rated voltage of 12kV power system. It is used as a protection and control unit for power grid equipment and industrial and mining enterprise power equipment. It is suitable for frequent operation under rated working current, or places where short-circuit current is broken many times.
The circuit breaker adopts an integrated design of the operating mechanism and the circuit breaker body, which can be used as a fixed installation unit or equipped with a special propulsion mechanism to form a handcart unit.
