The SKM-12 series vacuum circuit breaker is a newly developed product by our company. It adopts a solid-sealed pole structure and can also be designed with an insulated cylinder structure.
The SKM-12 series vacuum circuit breaker is a three-phase AC indoor switchgear rated at 50–60 Hz with a rated voltage of 12 kV. It is used as a protection and control unit for power grid equipment and industrial and mining enterprise power systems.
The primary part of the solid-sealed pole circuit breaker is manufactured using the APG process, which protects the vacuum interrupter and other main circuit components from impacts, dust, and condensation. It is suitable for applications requiring frequent operation at rated current, or multiple interruptions of short-circuit current, and is also ideal for harsh environmental conditions.
