ZN65A-40.5/T2000-31.5 Indoor Vacuum Circuit Breaker

The ZN65A-40.5/T2000-31.5 indoor vacuum circuit breaker is a type of high-voltage electrical equipment with the rated voltage of AC 40.5kV and the rated frequency of 50Hz. Its prominent feature is that its mechanical life reaches 120,000 times.

Application
This indoor vacuum circuit breaker is suitable to work as the control and protection switch for the power transmission and distribution systems in substations as well as industrial and mining enterprises. It is particularly suitable for metallurgy, arc steel making and other fields that require frequent operations.

Features
1. This high voltage circuit breaker has a simple structure. It adopts a spring operating mechanism which has complete operating functions and can be manually or electrically (AC or DC) operated.

2. The product is easy to maintain and there is no risk of explosion.

3. To prolong the mechanical life of the indoor vacuum circuit breaker, effective measures have been taken in the design, parts selection, surface treatment, and other aspects. For example, the spherical contact form is adopted for the connection of vacuum tube and upper outgoing line, making the force exerted on the vacuum interrupter more reasonable. Surface of the axle pin and other components have been specially processed, making them more wearproof.

After a series of improvement measures, the mechanical life of our indoor vacuum circuit breaker reaches 120,000 times. This is the first vacuum circuit breaker with such a long mechanical life in China.

Environmental Conditions
1. Altitude: ≤ 1,000m
2. Ambient Temperature: -15℃~ 40℃
3. Relative Humidity: Daily average ≤ 95%, monthly average ≤ 90%
4. Earthquake Intensity: < 8degree
5. The indoor vacuum circuit breaker should be used in places with no risk of fire or explosion, no corrosive gas, and no severe shaking.
