Product Description

 

Product Description

VS1-12 indoor high-voltage vacuum circuit breaker is an indoor switchgear for three-phase AC 50Hz and rated voltage 12KV power system, used as a protection and control unit for power grid equipment and industrial and mining enterprise power equipment. It is suitable for places requiring frequent operation under rated working current, or breaking short-circuit current several 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.
