Product Description
1.Product overview:
VS1-12 indoor high-voltage vacuum circuit breaker is used for 12KV power system indoor, industrial and mining switchgear, as a power grid equipment, industrial and mining enterprise power equipment protection and control unit. Due to the special advantages of vacuum circuit breakers, it is especially suitable for frequent operation that requires rated working current, or places where short-circuit current is repeatedly broken.
The circuit breaker adopts the integrated design of the operating mechanism and the circuit breaker body, which can be used as a fixed installation unit or a special propulsion mechanism to form a handcart unit, in which the fixed circuit breaker can add the corresponding interlock to meet the needs of XGN2, GG1A and other fixed cabinets.
