12KV Indoor Medium Voltage Vacuum Circuit Breaker is a high-voltage solution for indoor applications, featuring a rated voltage of 12KV and a frequency of 50Hz for three-phase AC systems. This product, known for its reliability, complies with the GB1984-89 standard. The design of this product is available in two configurations: the switch body and operating mechanism are integrated, and a modular version where the switch body and operating mechanism are separate. The integrated design is denoted as the ZN28-12 type, while the modular design is referred to as the-12 type, suitable for use in fixed switches such as GG-1A(Z) and XGN2A10(Z). This product can be paired with DC electromagnetic types CD17 and CD10A, as well as spring energy storage types CT17 and CT19.

In recent years, the field of engineering construction has faced increasing complexity due to advancements in technology and the growth of society and the economy. There is a rising demand for compact switch equipment that is smart and requires minimal maintenance. Both local and global manufacturers of switches are currently focusing on the development of 12KV 2500A Sf6 Sulfur Hexafluoride Infiilled Electrical Switchgear, also referred to as gas-insulated switchgear (C-GIS). These C-GIS systems encase high-voltage components like busbars, circuit breakers, isolating switches, and power cables in a housing with reduced gas pressure.
