Product Advantages

VS1-12 vacuum circuit breaker with lateral operating mechanism has many advantages:

Performance of circuit breaker:

E2-C2-M2

Stability and reliability:

it adopts the most mature frame-integrated spring operating mechanism, with over 20 years of market usage experience, ensuring safety, reliability, and high market recognition.

High applicability:

the switch three-phases are arranged from inside to outside, allowing the cabinet depth to be minimized to 900mm, making it suitable for various environments. The circuit breaker can be equipped with mechanical interlocks, facilitating interlocking with the cabinet's isolating switch and grounding switch, thereby enhancing safety.

Excellent insulation performance:

the main conductive circuit adopts APG high-strength epoxy resin composite insulated cylinder, which exceeds the IEC standard in terms of insulation performance.
