ZN105-18/T6300-63 Vacuum Circuit Breaker for Generator

According to the situation of control and protection circuit breaker for large-capacity load depending on imports in our power industry, our company developed this ZN105-18/T6300-63 vacuum circuit breaker for generator protection in 2008 by digesting and absorbing the German Siemens's 3AF technology imported in 1983. The rated current and rated short-circuit breaking current of this large-capacity circuit breaker are 6,300A and 63kA, respectively.

Features
1. With the rated voltage and frequency of 18kV and 50Hz respectively, this indoor AC high voltage switching device reaches the international advanced level in technical performance and it fills in the blank of domestic vacuum circuit breaker in this parameter level.

2. This vacuum circuit breaker for generator adopts the integrated design of operating mechanism and switch. The specialized spring energy storage type operating mechanism can be operated by AC, DC or hand.

3. With strong breaking capability, complete operating functions, long mechanical life, no explosion hazard and other advantages, this indoor circuit breaker is suitable to work as the control or protection switch in power plants, large-scale substations, as well as industrial and mining enterprises.

4. Our vacuum circuit breaker has excellent insulation property. It can fully meet the using requirement in indoor areas with the filthy condition of Grade II.

Conditions of Use Environment
1. Altitude: ≤2,000m
2. Ambient Temperature: -25℃~ 40℃
3. Relative Humidity: Daily average≤95%, monthly average≤90%
4. Earthquake Intensity: <8degree
5. The vacuum circuit breaker for generator should be used in places without fire, explosion, corrosive gas, or severe shaking.
