The VBI-12 indoor high-voltage vacuum circuit breaker has a complete solution and specifications, and is a new type of operation
Dynamic mechanism, simple and reliable. This model of circuit breaker has the following solutions:
1. There is a fully interchangeable solution with VSI.
2. One circuit is a fixed sealed pole (optional 650mm wide or 800mm wide cabinet) solution.
3. One time, the circuit did not adopt a fixed sealed pole and the phase spacing was 150mm (with a 650mm wide cabinet), which was more economical and practical.
