The VKYM-12 series permanent magnet solid-sealed indoor vacuum circuit breaker is a three-phase AC 50Hz, rated voltage 12kV indoor switching device. Equipped with our self-developed permanent magnet operating mechanism, it is used for the control and protection of electrical facilities in industrial and mining enterprises, power plants, and substations. This product features extremely high reliability and long service life, making it particularly suitable for harsh conditions such as frequent operation and multiple interruptions of short-circuit currents.
When the vacuum interrupter solid-sealed pole assembly of the standard model product is replaced with an ordinary insulation cylinder installation method, the model is designated as VKYM-12P.
