VYF-12GD Indoor Three Position Vacuum Circuit Breaker

The VYF-12GD is a three-position combined vacuum circuit breaker built on a modular framework, integrating vacuum circuit breaker, isolation switch, grounding switch, interlocking mechanism, and operating mechanism into a single compact assembly.

Rated for three-phase AC 50Hz power systems from 3.6 kV to 12 kV, the VYF-12GD serves control and protection duty in industrial and mining enterprises, power plants, and substations. The three-in-one architecture is built for panel space that a separate breaker-isolator-earth switch arrangement can’t match, positioning it as a miniaturized, high-performance choice for compact switchgear and ring main applications.
