The VDS-12/40.5 series vacuum circuit breaker is a new type of circuit breaker independently developed by Shanghai Pinggao Tianling Switchgear Co., Ltd. This product is suitable for indoor switchgear with rated voltage 12kV-40.5kV and three-phase AC 50Hz, serving as a control and protection unit for high-voltage electrical equipment. It is widely used in power plants, power grids, petrochemical, metallurgy, coal mines, and urban infrastructure construction projects such as subways, airports, and buildings. The circuit breaker adopts a modular spring operating mechanism, which is simple and mature with reliable and convenient operation. It can perform frequent operations or multiple short-circuit current interruptions within the working current range. The VDS series vacuum circuit breaker can be used alone or in N2X-12/24 and N2S/N2N-40.5 series gas insulated metal-enclosed switchgear, and can be interchanged with similar foreign products.
