Product Advantages

VS1-24C 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.

Good insulation performance:

The main conductive circuit adopts APG high-strength epoxy resin composite insulation, which has insulation performance higher than IEC standards.

High applicability:

The three-phase switch is distributed from the inside to the outside, and the cabinet depth can be as low as 1100mm, which is suitable for a variety of environments; the circuit breaker can be equipped with mechanical interlocking, which is convenient for isolating the switch from the cabinet, and the grounding switch is interlocked with each other, which is highly safe.

Products Application

VS1-24C vacuum circuit breaker has many applications:

Ⅰ

Urban community distribution systems

Ⅱ

Mobile substation equipment

Ⅲ

Industrial and mining enterprises
